Full textAbstract:
Modern design methodologies for control systems create controllers with dynamics which are of a similar order to the physical system being controlled. When these are implemented digitally as Infinite Impulse Response (HR) filters the processing requirements are extensive, in particular when high sample rates are necessary to minimise the detrimental effects of sample delay. The aim of the research was to apply signal processing techniques to facilitate the implementation of control algorithms in digital form, with the principal objective of maximising the computational efficiency, either to achieve the highest possible sample rates using a given processor, or to minimise the processor complexity for a given requirement. One of the approaches is to design a fixed point processor whose architecture is optimised to meet the computational requirements of signal processing for control, thereby maximising what can be achieved with a single processor. Hence the aim of the research was to head towards a processor architecture optimised for Control System Processing. The design of this processor is based on a unified structural form and it will be shown that controllers, represented either in state space form or as transfer functions, can be implemented using this unified structure. The structure is based on the σ-operator, which has been shown to be robust to changes in coefficients and hence require shorter coefficient wordlength to achieve a comparable performance to traditional z-operator based structures. Additionally, the σ-operator structures are also shown to have lower wordlength requirements for the internal variables. Also presented is a possible architecture for a Control System Processor and a model for the processor is developed and constructed using VHDL. This is simulated on a test bench, also designed in VHDL. The results of implementing a phase advance controller on the processor are then compared with those obtained from a MATLAB simulation.

One potential role for the architect of the future will be that of the digital craftsperson. Digital technology is allowing the designer to take control of and retool the entire design I fabrication I assembly process. With this new power, architects are crafting the digital tools and processes required to make architecture for the digital age.First, this thesis examines the notion of craft in the traditional way—how it has applied to architecture and building for most of history. This story recounts the architect's role in the designing and making of architecture, from the medieval master mason to the present-day architect. Craft, it is argued, is based on an understanding and skillful application of tools and processes as they relate to designing and making.The second part of this thesis applies this definition of craft to a new set of digital skills, tools, and processes. Digital craft is a combination of the skills of the architect, augmented by computers and computer-driven machines. Designing and making with digital tools is very dependent on a feedback loop driven process centered around a digital master model, into which, design information and data is input, and direct fabrication information and representation is output.The third part of this thesis describes the digital craftsperson through three case studies. The first case study recounts the process of digital tool-making. The second, describes the development of innovative fabrication and assembly techniques using digital tools and unconventional materials. The last case study recounts the design and fabrication process of a full-scale prototype by the author and a team of students.Department of Architecture

Full textAbstract:
The energy consumption of large-scale high-performance computer (HPC) systems has become one of the foremost concerns of both data-center operators and computer manufacturers. This has renewed interest in alternative computer architectures that could offer substantially better energy-efficiency.Yet, the for the evaluation of the potential of these architectures necessary well-optimized implementations of typical HPC benchmarks are often not available for these for the HPC industry novel architectures. The in this work presented LU factorization benchmark implementation aims to provide such a high-quality tool for the HPC industry standard high-performance LINPACK benchmark (HPL) for the eight-core Texas Instruments TMS320C6678 digitalsignal processor (DSP). The presented implementation could perform the LU factorization at up to 30.9 GF/s at 1.25 GHz core clock frequency by using all the eight DSP cores of the System-on-Chip (SoC). This is 77% of the attainable peak double-precision floating-point performance of the DSP, a level of efficiency that is comparable to the efficiency expected on traditional x86-based processor architectures. A presented detailed performance analysis shows that this is largely due to the optimized implementation of the embedded generalized matrix-matrix multiplication (GEMM). For this operation, the on-chip direct memory access (DMA) engines were used to transfer the necessary data from the external DDR3 memory to the core-private and shared scratchpad memory. This allowed to overlap the data transfer with computations on the DSP cores. The computations were in turn optimized by using software pipeline techniques and were partly implemented in assembly language. With these optimization the performance of the matrix multiplication reached up to 95% of attainable peak performance. A detailed description of these two key optimization techniques and their application to the LU factorization is included. Using a specially instrumented Advantech TMDXEVM6678L evaluation module, described in detail in related work, allowed to measure the SoC’s energy efficiency of up to 2.92 GF/J while executing the presented benchmark. Results from the verification of the benchmark execution using standard HPL correctness checks and an uncertainty analysis of the experimentally gathered data are also presented.Energiförbrukningen av storskaliga högpresterande datorsystem (HPC) har blivit ett av de främsta problemen för såväl ägare av dessa system som datortillverkare. Det har lett till ett förnyat intresse för alternativa datorarkitekturer som kan vara betydligt mer effektiva ur energiförbrukningssynpunkt. För detaljerade analyser av prestanda och energiförbrukning av dessa för HPC-industrin nya arkitekturer krävs väloptimerade implementationer av standard HPC-bänkmärkningsproblem. Syftet med detta examensarbete är att tillhandhålla ett sådant högkvalitativt verktyg i form av en implementation av ett bänkmärkesprogram för LU-faktorisering för den åttakärniga digitala signalprocessorn (DSP) TMS320C6678 från Texas Instruments. Bänkmärkningsproblemet är samma som för det inom HPC-industrin välkända bänkmärket “high-performance LINPACK” (HPL). Den här presenterade implementationen nådde upp till en prestanda av 30,9 GF/s vid 1,25 GHz klockfrekvens genom att samtidigt använda alla åtta kärnor i DSP:n. Detta motsvarar 77% av den teoretiskt uppnåbara prestandan, vilket är jämförbart med förväntningar på effektivteten av mer traditionella x86-baserade system. En detaljerad prestandaanalys visar att detta tillstor del uppnås genom den högoptimerade implementationen av den ingående matris-matris-multiplikationen. Användandet av specialiserade “direct memory access” (DMA) hårdvaruenheter för kopieringen av data mellan det externa DDR3 minnet och det interna kärn-privata och delade arbetsminnet tillät att överlappa dessa operationer med beräkningar. Optimerade mjukvaruimplementationer av dessa beräkningar, delvis utförda i maskinspåk, tillät att utföra matris-multiplikationen med upp till 95% av den teoretiskt nåbara prestandan. I rapporten ges en detaljerad beskrivning av dessa två nyckeltekniker. Energiförbrukningen vid exekvering av det implementerade bänkmärket kunde med hjälp av en för ändamålet anpassad Advantech TMDXEVM6678L evalueringsmodul bestämmas till maximalt 2,92 GF/J. Resultat från verifikationen av bänkmärkesimplementationen och en uppskattning av mätosäkerheten vid de experimentella mätningarna presenteras också.

A tese propõe uma abordagem cibersemiótica para processos de projeto a partir da perspectiva da mediação digital e de suas relações com a arquitetura contemporânea. Apresenta uma revisão dos processos digitais de projeto, com base na constatação de que a atuação de arquitetos e designers, em função dos modos de vida contemporâneos, passa a exigir atualmente uma postura diferenciada em relação ao gerenciamento das informações, assim como uma reflexão crítica em relação ao método projetivo utilizado na arquitetura da era digital. A tese utiliza como fundamentação teórica, os principais referenciais que tratam da Cibersemiótica, conforme proposta pelo filósofo dinamarquês Søren Brier, e de suas duas bases conceituais: a Semiótica de Charles Sanders Peirce e a Cibernética de Segunda Ordem, proposta por Heinz von Foerster. A tese propõe uma estrutura (framework) para análise de projetos a partir do olhar cibersemiótico, assim como propõe também uma estrutura (framework) para os próprios processos digitais de projeto. O trabalho é dividido em duas partes. A primeira parte, aborda processos de concepção e de produção digitais e as teorias utilizadas como fundamentação. Também define o quadro contextual que compara alguns projetos selecionados no recorte proposto e propõe uma estrutura de análise cibersemiótica destas referências. A segunda parte, apresenta estratégias para projeto digitais e propõe uma estrutura cibersemiótica para processos digitais de projeto. Acredita-se que a relevância da contribuição da tese se dá na direção da expansão do paradigma teórico cibersemiótico assim como na sua capacidade de potencializar processos digitais de projeto. Se outras espacialidades e interconexões deverão surgir a partir da atualização dos níveis de comunicação estabelecidos entre os diferentes sistemas, e de novos desafios sociais e culturais, é imprescindível que os arquitetos estejam atentos à compreensão das teorias e dos processos que estão disponíveis, para a otimização de todo o seu potencial de projeto na busca por ampliar as possibilidades para a Arquitetura e Urbanismo.The thesis explores the Cibersemiotic approach to design processes from the perspective of digital mediation and its relationship with contemporary architecture. It presents a review of existing digital design processes, based on the assumption that the practice of architects and designers, according to the contemporary modes of life, currently requires a different position in relation to the management of information, as well as a critical reflection on the design methods used in the architecture of the digital age. The thesis\' theoretical foundation is based on the Cibersimiotic work produced by the Danish philosopher Søren Brier, which unifies two important conceptual frameworks: the Semiotics by Charles Sanders Peirce and the Second Order Cybernetics proposed by Heinz von Foerster. The thesis proposes a structure (or framework) to analyze existing designs from the cibersemiotic point of view, as well as a structure (or framework) for the digital design processes themselves. The work is presented in two parts. The first examines the digital processes and production as well as the theories they are based on. This part also presents the theoretical context for the structure (or framework) used to analyse selected existing designs and introduces the framework. The second part presents strategies for digital design and proposes the cibersemiotic framework for digital design processes. It is believed the thesis contributes towards the expansion of the Cibersemiotic theoretical paradigm as well as provides a working framework for the increasingly complex processes of digital design. Assuming other spatialities and interconnections will arise from the update levels established from communication between different systems as well as new social and cultural challenges, it is essential that architects are aware of available theories and processes for optimizing design potential and expand the possibilities for Architecture and Urbanism.

Dissertação apresentada à Universidade Fernando Pessoa como parte dos requisitos para obtenção do grau de Mestre em Arquitetura e UrbanismoA presente dissertação de mestrado pretende abordar a influência das ferramentas digitais durante todo o processo arquitectónico, demonstrando a evolução desde o uso do lápis à utilização da robotização, alterando assim a forma de pensar do arquiteto, não deixando de referir a influência da arte na Arquitetura. Esta mudança de pensamento não é característica apenas dos dias de hoje, sendo visível ao longo da dissertação de que os grandes nomes da aquitetura, também passaram por uma fase de mudança de paradigma, fruto da evolução tecnológica, que levou ao aparecimento de novos estilos e teorias. O paradigma actual reflecte-se na utilização das ferramentas digitais e na forma como elas vão influenciar a Arquitetura dos dias de hoje. A variedade de ferramentas existentes permite que arquiteto explore a sua criatividade, de uma forma mais complexa e precisa. Como exemplo disso foram escolhidos três casos de estudo com o objetivo de demonstrar o desenvolvimento e a utilização das ferramentas digitais e como estas influenciam o arquiteto no processo de desenhar e pensar Arquitetura. Reflete-se no caso do Museu Guggenheim, um dos ícones da Arquitetura Contemporânea, do arquiteto Frank Ghery, sendo perceptível a grande utilização do software (CATIA), como uma ferramenta digital pioneira na Arquitetura. No caso do pavilhão ICD/ITKE, o arquiteto Achim Menges demonstra que o processo de cooperação, entre as várias ciências e as ferramentas origina uma Arquitetura final inovadora, resultante dos mesmos. Finalizando com o caso de estudo da Sagrada Família, um exemplo da utilização das ferramentas no processo de finalização da obra.
This master thesis aims to address the influence of digital tools throughout the architectural process, showing the evolution from the use of pencil to use the robot, thus changing the way of thinking of the architect, not forgetting to mention the influence of art in architecture. This change in thinking is not characteristic only of today, being visible along the thesis that the big names in architecture also went through a phase change of paradigm, the result of technological developments which led to the emergence of new styles and theories. The current paradigm is reflected in the use of digital tools and how they will influence the architecture of today. A variety of existing tools allows architect to explore their creativity in a more complex and accurately way. As an example was set the three case studies in order to demonstrate the development and use of digital tools and how they influence the architect in the process of designing and thinking architecture. It is reflected in the case of the Guggenheim Museum, one of the icons of contemporary architecture, by the architect Frank Gehry, with noticeable great use of the software (CATIA), as a pioneering digital tool in architecture. In the case of ICD / ITKE pavilion, architect Achim Menges demonstrates that the process of cooperation between the various sciences and tools lead to innovative end architecture, resulting thereof. Finishing with the case of the Sagrada Família study, an example of the use of the tools in the work of finalizing the construction process.

Partindo da hipótese de que as tecnologias digitais são simultaneamente meios e ambientes capazes de influenciar e viabilizar a emergência de um pensamento arquitetônico pronto a incorporar a complexidade, o objetivo do presente trabalho é ampliar a compreensão acerca das interfaces entre complexidade e processos de design em arquitetura. No percurso de construção dessa abordagem, buscamos entender a abrangência da mudança colocada pela complexidade, seu histórico, e seus princípios fundamentais, obtendo subsídios para definir critérios de seleção e análise de exemplos da emergência da complexidade em arquitetura, focalizando os processos de design. Utilizamos um recorte temporal em dois períodos décadas de 1960 e 1970, e décadas de 1990 e 2000 , distinguindo dois momentos específicos intrinsecamente conectados. A intenção é contribuir para uma compreensão efetiva da arquitetura não apenas, ou principalmente, como objeto, mas como um sistema complexoorganizado e, sobretudo, organizante.Assuming digital technologies simultaneously as media and environment that influence and make feasible the emergence of an architectural thought ready to incorporate the complexity, the goal of this work is to increase the understanding circa interfaces between complexity and architectural design processes. This approach draws on understanding the scope of the change brought by complexity, its historical, and its fundamental principia, aiming to achieve subsides for defining criteria to analyze and select examples of complexity emergence in architecture, focusing on design process. Two periods of time were selected from 1960s to 1970s and, from 1990s to 2000s , distinguishing two specific moments closed related. The intention is to contribute for an effective understanding of architecture not merely or specifically as object, but as a complex system, simultaneously organized and organizer.

Full textAbstract:
Contemporary small office phone systems are specialized computers that connect a variety of phones within the office and to the local phone company. These systems use digital signaling processors (DSPs) to convert signals from analog to digital and vice-versa. Many different types of applications run on the DSPs and different businesses have varying application needs. Given the systems have limited amounts of DSP resources and growing numbers of applications for a phone system, an administrator needs a way to configure the uses of resources based on their individual business needs.
This thesis provides an overview of a system for configuring resources on various types of DSP hardware some of which are removable and have differing tradeoffs between application uses. The system has to be able to change resource allocations while the phone system is running with minimal interruptions to calls. The configuration system needs to be designed to be flexible enough that new applications or DSP hardware could be supported without major changes to code.
This thesis presents a system that uses a database-driven model along with algorithms that optimize configuration of DSP hardware given the administrator’s individual application needs.

Full textAbstract:
The Waves instruments aboard the Juno and Radiation Belt Storm Probe (RBSP) spacecraft represents the next generation of space radio and plasma wave instrumentation developed by the University of Iowa's Radio and Plasma Wave group. The previous generation of such instruments on the Cassini spacecraft utilized several analog signal-conditioning techniques to compress and condense scientific data. Compression techniques are necessary because the plasma wave instruments can often generate significantly more science data than can be transmitted using the narrow telemetry channel of the hosting spacecraft. The next generation of plasma wave instrumentation represents a major shift of analog signal conditioning functionality to the digital domain, drastically reducing the amount of power and mass required by the instrument while simultaneously further condensing scientific data, increasing the precision of plasma emission measurements, and adding flexibility. The solution presented in this thesis is to utilize a low-cost radiation tolerant field programmable gate array (FPGA) that serves as a space qualified implementation platform for a custom designed general-purpose digital signal processor, called the WvFEv3.

Modern architecture has lost its sense of place by the adoption of practices like standardization and universal modularity, over the focus and influence of unique local building practices. However, looking outside of the cultural main stream works of architecture, there exists some built structures with such purity around how they were constructed and a form of honesty deeply embedded within their material usage. Having been idealized in such a locally specific manner, these attributes become the essence of belonging that ties the building to its particular place. In this thesis, I have considered architecture both within regional or vernacular architectural traditions and the unconstrained means and methods of modern architecture. I looked at how modern technologies related to fabrication can be influenced by the subtle adaptations that traditional architecural crafts have developed, unique to specific regions.Master of Architecture

Parte do pressuposto que o suporte digital, espaço virtual e interativo para a criação do projeto, é conseqüência da evolução gradual dessas tecnologias no fluxo contínuo das transformações culturais. Entendendo esse fluxo como processo, localiza na segunda metade do século XX a emergência de uma nova racionalidade apoiada nos termos relação, sistema e organização no lugar dos termos modernos função, estrutura e ordem. O pensamento diagramático, a analogia e o dialógico e experimental priom (material/procedimento) caracterizam procedimentos que, assumindo diferentes configurações, possibilitam o reconhecimento de uma arquitetura maquínica.The thesis intend to understand the mediation of the numerical technologies on architectural procedures (thought and gênesis). It supposes that the digital support as a virtual and interactive space for design is resulting of a gradual evolution of these technologies undergoing through the continuous flux of cultural transformations. It locates at the XX century second half the emergence of a new racionality based on the terms relation, system and organization replacing the modern concepts of function, structure and order. Diagrammatic thought, analogy and the experimental and dialogical priom (material/procedure), enable the recognition of a machinic architeture.

O ensino de projeto arquitetônico é, via de regra, o tronco da estrutura curricular dos cursos de Arquitetura no Brasil. Não obstante, com o passar do tempo, o ensino de projeto se mostra à prova de definições estáticas a respeito de metodologias de ensino para sua prática e aprendizado. São inúmeras as metodologias propostas e em desenvolvimento para o ensino de projeto, pois a elaboração de um projeto envolve a inter-relação entre diversas categorias de conhecimentos e habilidades, que interagem de modo não-linear entre si. Com a revolução digital do exercício profissional de arquitetura, um novo paradigma se apresenta como um particular desafio para as universidades brasileiras: introduzir no currículo do curso metodologias de ensino de projeto arquitetônico estruturadas, de modo articulado com meios e plataformas digitais que exploram as ferramentas computacionais para além do limiar da simples representação gráfica. Analisando o panorama geral, é possível notar que esta prática ainda está em estágio inicial no País (ROMCY, 2017). Segundo Orciuoli, (2009) a arquitetura digital ainda é vista com certa resistência pelas próprias faculdades de arquitetura. Neste sentido, esta dissertação se propõe a pesquisar a implantação de estratégias para o desenvolvimento de projeto utilizando o ambiente digital algorítmico e paramétrico em uma disciplina de projeto arquitetônico, assim como a instrumentalização necessária para a utilização destas ferramentas computacionais Foi desenvolvida uma pesquisa-ação em disciplinas do 4ª semestre da faculdade de arquitetura onde se propuseram exercícios relacionando conteúdos instrumentais às disciplinas de projeto para conectar o conhecimento computacional às estratégias projetuais. Na sequência, foi realizada uma análise sobre a integração entre softwares de desenho em plataforma BIM (Building Information Modelling) e softwares de modelagem algorítmica/paramétrica. Com isso, pretendeu-se fornecer subsídios instrumentais para que os alunos possam explorar estratégias projetuais digitais que utilizassem formas complexas, diminuindo assim os percalços habituais relativos à falta de destreza técnica na ferramenta digital tanto para o raciocínio projetual quanto para a posterior representação gráfica de suas propostas. Ademais foram analisados comparativamente os dados fornecidos pelos alunos antes e depois da implementação da abordagem de projeto digital, a fim de detectar problemas, potencialidades e efetividade da estratégia de ensino proposta.The teaching of architectural design is commonly the main curricula structure in architectural graduation in Brazil. Even though, over time, project teaching has been difficult to define by static methodologies to teach its practice and learning. In fact, there are lots of methodologies proposed and in development to teach the activity of design. That´s because the design activity involves inter relationships between several knowledge domains and skills that´s interact in a nonlinear way. With the digital revolution of architectural practice, a new paradigm reveals itself as a particular challenge to Brazilians architecture schools: how to introduce, in the course curricula, structured methodologies to architectural design teaching in an articulated manner with digital media that explores computational tools beyond graphic representations boundary. Analyzing the general panorama, it is possible to note that this practice is still in its initial stages in Brazil (ROMCY, 2017). According to Orciuoli, (2009) digital architecture is still seen with some resistance by the architecture faculties themselves. In this sense, this work proposes to study strategies to develop projects using digital algorithmic and parametric media in a discipline of architectural design as well as the knowledge necessary to carry on these computational tools An action research was developed in disciplines of the 4th semester of the architecture faculty where they were proposed exercises relating instrumental disciplines with design disciplines to connect computational knowledge to design strategies. Next was analyzed the integration between a BIM software with a algorithmic/parametric modeling software. To this end, instrumental grants were able to assist people in the development of digital capacities, using the complex forms reducing in this way the usual gaps related to a lack of technical skills on reasoning or drawing with digital tool. Data developed by the students before and after the implementation of the digital design approach was analyzed comparatively in order to detect problems, potentialities and effectiveness of the proposed teaching strategy.

The system clock has been omnipresent in most mainstream chip designs. While simplifying many design problems the clock has caused the problems of clock skew, high power consumption, electromagnetic interference, and worst-case performance. In recent years, as the timing constraints of synchronous designs have been squeezed ever tighter, the efficiencies of asynchronous designs have become more attractive. By removing the clock, these issues can be mitigated. How- ever, asynchronous designs are generally more complex and difficult to debug. In this paper I discuss the advantages of asynchronous processors and the specifics of some asynchronous designs, outline the roadblocks to asynchronous processor design, and propose a series of asynchronous designs to be used by students in tandem with traditional synchronous designs when taking an undergraduate computer architecture course.

Resumo: Anúncios recentes sobre os limites do desempenho dos processadores devido ao alcance da barreira térmica têm motivado a pesquisa sobre novas organizações arquiteturais e modelos de execução que visam continuar o aumento de desempenho dos processadores. Este trabalho propõe uma nova arquitetura de processador denominada 2D-VLIW. A arquitetura possui uma organização arquitetural baseada em uma matriz bidimensional de unidades funcionais e de registradores distribuídos ao longo dessa matriz. O modelo de execução 2D-VLIW possibilita que instruções longas, formadas por operações simples, sejam buscadas na memória e executadas sobre a matriz de unidades funcionais. Além disso, são propostos algoritmos para geração de código para extrair o paralelismo e preparar o código para ser executado sobre a arquitetura. Algumas contribuições deste trabalho são a concepção de uma nova arquitetura de processador que explora paralelismo em nível de instruções através de um novo arranjo dos elementos arquiteturais, a adoção de um modelo de execução que captura a geometria dos DAGs e associa os vértices e arestas desses DAGs aos recursos do hardware, um conjunto de algoritmos para escalonamento de instruções, a alocação de registradores e a codificação de instruções na arquitetura 2D-VLIW. Os resultados experimentais comparam o desempenho do modelo de execução dessa arquitetura com o modelo EPIC adotado pelo processador HPL-PD. O speedup obtido por 2D-VLIW foi de 5% at'e 63%. A estratégia de escalonamento adotada por 2D-VLIW foi também avaliada e os ganhos obtidos através do OPC e OPI foram até 4 vezes melhores que aqueles obtidos por um algoritmo de escalonamento baseado em list scheduling
Abstract: Recent announcements on processor performance limits due to the thermal barrier have motivated research into innovative architectural organizations and execution models to sustain the increase of performance. This work proposes a new architecture named 2D-VLIW. The architecture provides a new architectural organization of the processing elements by using a two-dimensional functional units matrix and registers spread out along this matrix. The 2D-VLIW execution model fetches long instructions comprised of simple operations in the memory and dispatches these operations to the matrix. Moreover, the work presents new algorithms for code generation which are the responsible for extracting the parallelism of the applications and preparing the code for the 2D-VLIW architecture. Some contributions of this work are a new high performance architecture that exploits instruction level parallelism by a new arrangement of the architectural elements, the adoption of an execution model that captures the geometry of the DAGs and matches them to the hardware resources, a set of algorithms for code generation that make them possible to schedule instructions, allocate registers and encode long instructions of the 2D-VLIW architecture. Experimentos were used for comparing the performance of the 2D-VLIWexecution model to the EPIC execution model of the HPL-PD architecture. The speedup obtained by 2D-VLIW ranges from 5%-63% for all the evaluated programs. The scheduling strategy based on subgraph isomorphism was also evaluated and the OPC and OPI gains were up to 4× better than that of the list scheduling algorithm

This study aims to analyze and evaluate the influence of digital technologies on the inter-action of design and manufacturing processes by representing an outlook of digital tech-nologies through developments in modeling capabilities, manufacturing techniques, mate-rial science, and design strategies.
The digital era reached by the technological developments in different fields of sci-ence influenced the field of architecture, just like the others. Thus, a new kind of spa-tial and tectonic quality in architecture is emerging with the lately introduced design tools and materials that are novel to the building industry, while redefining the role of architect in this contemporary medium.
The evolutionary process of Frank O.

Através de uma percepção interdisciplinar, a pesquisa apresenta um quadro de contribuição para a teoria da arquitetura contemporânea que analisa relações entre conceitos, processos e representações. O trabalho investiga processos de projeto presentes na arquitetura contemporânea a partir da assimilação de três conceitos-chave: 1) diagrama, 2) dobra e 3) parâmetro; e as correspondentes traduções na arquitetura, através dos discursos e práticas de arquitetos. A pesquisa insere-se no âmbito da teoria e crítica do projeto de arquitetura e o recorte histórico está situado entre a década de 1970 até o momento, examinando as expressões projetuais e teorias de arquitetos como Peter Eisenman, Greg Lynn, Patrik Schumacher (Zaha Hadid and partners), entre outros. O problema da pesquisa é identificar de que modo o caráter conceitual experimentado pelos processos de projeto no primeiro período do recorte diagrama -, passou a intermediar uma base teórica paralela ao avanço do uso digital dobra e se modificou, no terceiro período, para enfatizar discursivamente os processos e a manipulação formal permitida pelas técnicas e tecnologias digitais avançadas parâmetro. Os objetivos são compreender os elementos dessa transição, traçar paralelismos e diferenças entre os processos, compreendendo que a história desses entrelaçamentos não é linear e cumulativa, mas atravessada por recorrências e reapropriações. Os autores foram escolhidos devido a sua produção teórica e inserção no debate internacional para os temas escolhidos, por compartilharem a absorção de teorias advindas do pós-estruturalismo de base filosófica - principalmente de Gilles Deleuze -, além de estabelecerem uma atividade projetual de caráter experimental, que permitiu à pesquisa a análise de diversos estudos de caso.Through an interdisciplinary perception, the research presents a contribution framework for the theory of contemporary architecture that examines some relations between concepts, processes and representations. The work investigates design processes present in contemporary architecture from the assimilation of three key concepts: 1) diagram 2) fold and 3) parameter; and corresponding translations in architecture through the discourses and practices of architects. The research falls within the sphere of the theory and criticism of architecture design and the historical period is set between the 1970s up to now, examining the projective expressions and theories of architects such as Peter Eisenman, Greg Lynn, Patrik Schumacher (Zaha Hadid and partners), among others. The problem of research is to identify how the conceptual nature experienced by design processes in the first period of study - diagram - began to intermediate a parallel theoretical basis for the advancement of digital use - fold - and changed in a third period to emphasize discursively processes and formal manipulation allowed by the technical and advanced digital technologies - parameter. The objectives are understand the elements of this transition, draw parallels and differences between the processes, understanding that the history of these entanglements is not linear and cumulative, but crossed by recurrences and reappropriations. The authors were chosen due to their theoretical production and insertion in the international debate on the topics chosen, for sharing the assimilation of theories stemming from the philosophical basis of post-structuralism - especially from Gilles Deleuze - as well as established a design activity of experimental features, which allowed the analysis of several case studies.

Resumo: A utilização de técnicas de Fabricação Digital está cada vez mais presente no campo da arquitetura e construção por todo o mundo, devido aos avanços tecnológicos que os sistemas CAD (Computer-aided Design) e CAM (Computer-aided Manufacturing) têm proporcionado aos processos de concepção e produção da obra arquitetônica. As possibilidades que essas ferramentas oferecem aos arquitetos e projetistas abrem caminho para novas abordagens de projeto, que permitem o uso da produção automatizada sem a necessidade de uma padronização tão rígida como aquela imposta pelo sistema industrial. Entretanto, nota-se que a aplicação dos métodos de Fabricação Digital no processo de produção do espaço edificado no Brasil é lento, quando comparado a outros países onde a tecnologia necessária para o exercício da técnica já se encontra amplamente difundida. A presente pesquisa tem como foco investigar a aplicação da Fabricação Digital, por intermédio de processos file-to-factory na produção arquitetônica de elementos para a construção civil, mais especificamente com o uso de técnicas subtrativas de corte 2D. Após um levantamento sobre o estado da arte da área e o desenvolvimento de dois estudos de caso, o método utilizado foi a pesquisa-ação, por meio de um exercício de aplicação do conceito file-to-factory. O processo de projeto foi documentado detalhadamente e analisado para a sistematização dos procedimentos, que servirão de referência para futuras aplicações no campo da arquitetura. Espera-se, com isso, contribuir para a divulgação dessas novas tecnologias na produção arquitetônica no cenário brasileiro
Abstract: The use of Digital Fabrication techniques is increasingly present in the field of architecture and construction throughout the world. Systems such as CAD (Computer-aided Design) and CAM (Computer-aided Manufacturing) have provided technological advances to the architectural design and production process. The possibilities that these tools provide to architects and designers introduce new design approaches, which allow the use of automated production without the rigid standardization imposed by the industrial system. However, it can be noticed that the use of Digital Fabrication methods in the built environment production process in Brazil is slow when compared to other countries where the technology is widely incorporated. This research focuses on investigating the application of Digital Fabrication, through file-to-factory processes in the production of architectural elements for the construction industry, specifically with the use of 2D subtractive cutting techniques. After a survey on the state of the art in the field and two case studies, the method used was an action research through a file-to-factory exercise. The design process was documented in detail and analyzed in order to systematize the procedures as a reference for future applications in architecture. As a result we expect to contribute to the dissemination of these new technologies in architectural production in the Brazilian scenario

Partindo da hipótese de que o uso da arte da memória pode ser compreendido como um sistema-processo de design para a concepção de espaços no contexto da cultura digital, o objetivo do presente trabalho é construir uma compreensão ampliada do design de espaços que dão suporte ao armazenamento estruturado de informações, relacionando imagens e lugares. A investigação contempla o uso da arte da memória na concepção de espaços e seus princípios fundamentais desde a antiguidade clássica até os dias atuais, através de exemplos, construindo um entendimento do desenvolvimento e das conexões estabelecidas por essa arte em três momentos: das origens como parte da retórica na antiguidade clássica à sua apropriação pela escolástica medieval, passando à sua apropriação pela tradição Hermético-Cabalística no Renascimento, com os modelos de teatros da memória, à sua incorporação no processo de concepção de espacialidades por arquitetos e mídia artistas contemporâneos. A intenção é contribuir para o entendimento da arte da memória como auxiliar à criação de espaços como sistemas da memória.Assuming that the use of the art of memory can be understood as a system-design process for the conception of spaces in the context of digital culture, the present work goal is to construct a base understanding of design of spaces that give support to structured information storage by connecting images and places. The research contemplates the use of the art of memory, concerning the conception of spaces, from its fundament, of the classical antiquity to the present days, by examples, building an understanding of the development and connections concerning three moments of this art: from its origins as a part of rhetoric in the classical antiquity to its assimilation by the middle ages scholastics, to its appropriation by Hermetic-Cabalistic tradition in the renaissance and its memory theatres models, and finally to its contemporary incorporation in the space design processes by architects and media artists. The aim is to contribute to the understanding of the art of memory as an aid to the conception of spaces as memory systems.

Full textAbstract:
Speech recognition systems have been implemented using a wide range of signal processing techniques including
neuromorphic/biological inspired and Digital Signal Processing
techniques. Neuromorphic/biologically inspired techniques, such as silicon cochlea models, are based on fairly simple yet highly parallel computation and/or computational units. While the area of digital signal processing (DSP) is based on block transforms and statistical or error minimization methods.
Essential to each of these techniques is the first stage of
extracting meaningful information from the speech signal, which is known as feature extraction. This can be done using biologically inspired techniques such as silicon cochlea models, or techniques beginning with a model of speech production and then trying to separate the the vocal tract response from an excitation signal. Even within each of these approaches, there are multiple techniques including cepstrum filtering, which sits
under the class of Homomorphic signal processing, or techniques using FFT based predictive approaches. The underlying reality is there are multiple techniques that have attacked the problem in speech recognition but the problem is still far from being solved. The techniques that have shown to have the best recognition rates involve Cepstrum Coefficients for the feature extraction and Hidden-Markov Models to perform the pattern recognition.
The presented research develops an analog system based on
programmable analog array technology that can perform the initial stages of auditory feature extraction and recognition before passing information to a digital signal processor. The goal being a low power system that can be fully contained on one or more integrated circuit chips. Results show that it is
possible to realize advanced filtering techniques such as
Cepstrum Filtering and Vector Quantization in analog circuitry. Prior to this work, previous applications of analog signal processing have focused on vision, cochlea models, anti-aliasing filters and other single component uses. Furthermore, classic designs have looked heavily at utilizing op-amps as a basic core building block for these designs. This research also shows a novel design for a Hidden Markov Model (HMM) decoder utilizing circuits that take advantage of the inherent properties of subthreshold transistors and floating-gate technology to create low-power computational blocks.

Resumo: Nos últimos dez anos as novas tecnologias digitais e os processos de produção pós-industriais têm se firmado como grandes aliados do processo de projeto arquitetônico, da fabricação de componentes e da construção do espaço construído. Esta pesquisa analisa as inovações recentes na área de informática aplicada à arquitetura, tendo em vista sua incorporação no processo de projeto e na formação do arquiteto. Em especial, discute a importância da inserção de prototipagem e fabricação digitais no currículo de arquitetura, de maneira integrada às disciplinas de projeto e demais matérias da grade curricular. O trabalho teve início com um levantamento de teses desenvolvidas nos últimos anos na área de informática aplicada à arquitetura, na qual se constatou uma grande diferença de foco entre os trabalhos desenvolvidos no Brasil e no exterior. A partir dessa constatação, foram desenvolvidos experimentos pedagógicos no curso de Arquitetura e Urbanismo da FEC, na UNICAMP, com o objetivo de introduzir conceitos sobre as tecnologias de prototipagem e fabricação digitais e seu uso no processo de projeto. A partir dos resultados obtidos, foi desenvolvi da uma proposta de inserção dessas novas tecnologias no curso analisado em particular, e nos demais cursos de arquitetura brasileiros em geral, de maneira integrada às demais disciplinas do currículo. Espera-se que os resultados obtidos nesta pesquisa contribuam para a inserção dessas tecnologias na formação do arquiteto no Brasil, e conseqüentemente para uma evolução da arquitetura brasileira, com a incorporação dos novos métodos de produção pós-industriais.
Abstract: During the past 10 years the new digital technologies and the post-industrial production have been incorporated to the design process, to the production of building parts, and to the construction of buildings. The present research analyzes the recent innovations in the area of technologies applied to architecture, aiming at its incorporation into the design process as well as in architectural education. It discusses the importance of the insertion of digital prototyping and fabrication in the architecture curriculum, in such a way that it promotes the integration between the design studio and the other subjects in the curriculum. The work began with a survey of recent theses and dissertations about technology applied to architecture. The survey showed that there is still a great difference between the works developed in Brazil and abroad. Next, some pedagogical experiments were developed at FEC, aiming at the introduction of digital prototyping and fabrication in the design process. A proposal of insertion of these new technologies in architecture courses was then developed. The results obtained in this research are expected to contribute to the insertion of these technologies in the architectural education in Brazil, hopefully leading to an evolution of brazilian architecture with the use of new post industrial production methods.

Resumo: O uso de displays interativos introduz novas possibilidades de participação e interação entre os componentes de uma equipe no processo projetual em arquitetura, em suas diversas fases. O presente estudo se concentra em duas questões. A primeira etapa da pesquisa consistiu em uma revisão da bibliografia sobre a importância do desenho no processo de projeto. Em seguida foi realizado um levantamento das tecnologias disponíveis que permitem produzir esboços manuais diretamente em formato digital. Dentre essas tecnologias, duas foram escolhidas para o desenvolvimento da parte experimental da pesquisa: a lousa interativa e a mesa digitalizadora opaca. A etapa experimental da pesquisa teve inicio com um estudo piloto para avaliar a potencialidade e a interação dos equipamentos com os alunos. Em seguida a metodologia sofreu alterações em função dos resultados preliminares e um novo experimento foi realizado no segundo semestre de 2008, nesse experimento pode-se obter resultados que auxiliaram a descrever benefícios e deficiências do uso de displays interativos no processo de projeto.

Abstract: The use of interactive displays introduces new possibilities for participation and interaction between components of a team in the design process of architecture in various stages. The present study started with the identification of the difficulties in sharing information that design teams have to deal with during presential meetings. The study has focused on two issues. The first stage of the research consisted of a review of the literature about the importance of collaboration in the design process. Next, a survey of the available technologies that allow the production of manuals sketches directly in digital format was performed. Among these technologies, two were chosen for the development of an experimental research: an electronic whiteboard and an opaque tablet. The experimental stage of research began with a preliminary study to assess the capabilities of the equipment. The initial methodology was adjusted, according to the preliminary results, and a new experiment was performed in the second semester of 2008. This experiment allowed to obtain results that describe the benefits and shortcomings of the use of interactive displays during the design process. The present research is expected to contribute to the integration of digital media in design education and to help reformulating the dynamics of the architectural design studio

Abstract The multiple-input multiple-output (MIMO) technique combined with an orthogonal frequency division multiplexing (MIMO--OFDM) has been introduced as a promising approach for the ever increasing capacity and quality of service (QoS) requirements for wireless communication systems. An efficient radio spectrum utilization expects a flexible transceiver solution, which has been the reason for the development of the software defined radio (SDR) technologies which in their turn are expected to enable the creation of cognitive radios. As a result, any radio solution could be invoked on demand on any platform. In this thesis work, we have studied detector algorithms and programmable processor architectures in order to find practical solutions for the future wireless systems. A programmable receiver can reduce the energy dissipation of the receiver by changing the detection algorithm based on the current channel realizations. To provide a realistic aspect to the implementations in different channel realizations, we present a wide state-of-the-art detector comparison. In addition, we present an extensive number arithmetic and word length study in order to evaluate realistic hardware complexity and energy dissipations of the implementations. The study includes a comprehensive design chain from the algorithm development to the actual processor design and finally programming software for the platforms. We evaluate single and multi-core processor implementations by comparing the achieved results to the Long Term Evolution (LTE) performance requirements. We implement detectors on digital signal processors (DSPs), graphics processing unit (GPU) and transport triggered architecture (TTA). The implementation results are compared in throughput, silicon area and energy efficiency. Finally, we discuss the advantages and disadvantages of the architectures and the implementation effortTiivistelmä Usean antennin tekniikka yhdistettynä ortogonaaliseen taajuusvaihtelumodulointiin lähetin-vastaanotimessa on esitetty eräänä lupaavana ratkaisuna jatkuvasti kasvaviin kapasiteetti- ja palvelunlaatuvaatimuksiin langattomissa tietoliikennejärjestelmissä. Tehokas radiospektrin käyttö edellyttää joustavaa lähetin-vastaanotinratkaisua, mikä on ollut syynä ohjelmistoradioteknologioiden kehitykselle. Ohjelmistoradioiden kehityksen on puolestaan odotettu mahdollistavan kognitiiviradioiden syntymisen. Tuloksena, mikä tahansa radiosovellus voitaisiin herättää tarpeen mukaan millä tahansa ohjelmoitavalla sovellusalustalla. Tässä väitöskirjatyössä tutkitaan ilmaisinalgoritmeja sekä ohjelmoitavia prosessoriarkkitehtuureja tarkoituksena löytää käytännöllisiä ratkaisuja tulevaisuuden langattomiin järjestelmiin. Ohjelmoitavalla vastaanottimella voidaan vähentää vastaanottimen energiankulutusta vaihtamalla ilmaisinalgoritmeja vallitsevan kanavatilan mukaan. Työssä esitellään laaja, viimeisintä tutkimusta edustava ilmaisinalgoritmivertailu, joka antaa realistisen näkökannan toteutuksiin erilaisissa kanavatiloissa. Lisäksi työssä esitellään numeroaritmetiikka- ja sananpituustutkimus, jonka tarkoituksena on arvioida toteutusten realistista kovokompleksisuutta sekä energiankulutusta. Tutkimus sisältää kattavan suunnitteluketjun algoritmikehityksestä todelliseen prosessorisuunnitteluun ja lopulta algoritmin ohjelmointiin tietylle sovellusalustalle.

O cenário de metrópoles como Londres, Nova Iorque, Dubai, Shangai, Seul e outras exibe alguns tipos de edifícios com formas orgânicas e fluidas, que fazem parte de uma proposta que utiliza ferramentas informacionais e programação para a sua criação e materialização. Este trabalho investiga como viabilizar as superfícies consideradas complexas, desses edifícios, através do tema Projeto para a Produção, etapa que aprofunda o processo do fazer, posterior à criação. A complexidade é caracterizada pela utilização de um alto nível tecnológico para a elaboração dos sistemas, do componente em sua morfologia e, em relação ao módulo, material e geometria (PAOLETTI, 2006). Para o entendimento do problema, o texto contextualiza o momento contemporâneo e a participação dos instrumentos digitais no cotidiano, fazendo uma retrospectiva dos modos de produção e da automação da indústria, e faz um paralelo com a construção civil. Trata desde a 1a. Revolução Industrial até a 4a. Revolução Industrial, de acordo com Schwab (2016).Para discutir o Projeto para a Produção, verifica-se o estado da arte, posteriormente confrontando duas vertentes conceituais da atuação do papel do arquiteto no processo: uma que defende que os profissionais têm atuado mais próximos à fabricação digital, com arquivos enviados diretamente para a fábrica File to Factory (Arquivo-Fábrica) , e outra que entende que o processo é distribuído em etapas e equipes específicas e depende de habilidades e conhecimentos particulares para a produção do objeto. Este trabalho apresenta dois casos desenvolvidos na Itália: o primeiro projetado pelos arquitetos do escritório Norman Foster & Associates, o Pavilhão da União dos Emirados Árabes para a exposição internacional de Milão, que foi confeccionado com painéis de argamassa armada estampados com a textura das dunas do deserto, e o segundo, a torre corporativa do escritório Zaha Hadid Architects, do complexo CityLife Milano, que possui a superfície de vedação com painéis de vidro em formato de paralelogramas, que evidenciam a torção da torre em seu eixo vertical. Finalmente, o trabalho propõe um modelo de Projeto para a Produção de superfícies complexas a partir do aprofundamento dos estudos de caso, considerando que a proposta faz parte de uma etapa do projeto que é efetuada por equipes de profissionais habilitados para a elaboração dos detalhamentos, busca de soluções, pesquisa aprofundada a respeito dos materiais a serem utilizados e dos requisitos necessários para a realização dos trabalhos no local de implantação.The scenery of big cities such as London, New York, Dubai, Shanghai and Seoul exhibits some types of buildings with organic and fluid shapes that are part of a proposal that uses information tools and programming for their creation and feasibility. This work in¬vestigates how feasible surfaces considered complex through the theme Design for Pro¬duction, a stage that deepens the process of making, after creation. The complexity is characterized as the use of a high technological level for the elaboration of the systems, of the component in its morphology and, in relation to the module, material and geom¬etry (PAOLETTI, 2006). For the understanding of the problem, the text contextualizes the contemporary moment and the participation of the digital instruments in the daily life, making a retrospective of the ways of production and the automation of the industry and parallels with the civil con¬struction. It deals from the 1st. Industrial Revolution until the 4th. Industrial Revolution, according to Schwab (2016). In order to discuss the Design for Production, the state of the art is verified, later confront¬ing two conceptual aspects of the role of the architect in the process, one that argues that the professionals have directly acted in the digital manufacture with files sent directly to the factory File to Factory and another that understands that the process is distribut¬ed in stages and specific teams and depends on particular skills and knowledge to the production of the object. It presents two cases developed in Italy: the first one designed by Norman Foster & As-sociates, the United Arab Emirates Pavilion for the Milan International Exbition, which was made with panels of Glass Fiber Reinforced Concret stamped with the texture of the desert dunes and the second one a corporate tower designed by Zaha Hadid Architects office for the CityLife Milano, which has a trapezoidal glass panel sealing surface that demonstrates the twisting of the tower on its vertical axis. Finally, the work proposes a model of a Design for Production of complex surfaces from the deepening of the case studies, considering that the proposal is part of a project stage carried out by teams of professionals qualified to perform the details, search for solutions, in-depth research regarding the materials to be used and the requirements necessary to carry out the works at the place of implantation.

Com a evolução das tecnologias de informação e comunicação, é necessário que o cidadão seja incluído na cultura digital para que possa fazer parte da sociedade globalizada dos dias atuais. Assim, também é tarefa da escola a busca da inclusão dos sujeitos nessa cultura digital. A utilização das novas tecnologias é importante e deve ser considerada quando se planejam atividades de aprendizagem com os alunos da Escola Básica. O principal objeto de pesquisa dessa tese foi o estudo dos processos cognitivos que envolvem aspectos da aprendizagem da Química com o uso dessas tecnologias. Procurou-se verificar como uma Arquitetura Pedagógica orientada para os alunos, contendo atividades experimentais, produção de vídeos e elaboração de modelos digitais no ambiente Squeak-Etoys, pode contribuir para a construção do conhecimento químico. Entende-se a Arquitetura Pedagógica como um conjunto de estratégias, dinâmicas de grupo, softwares educacionais e ferramentas de apoio à cooperação que possam favorecer a aprendizagem. A análise dos processos vivenciados pelos sujeitos da pesquisa foi fundamentada pela Epistemologia Genética de Jean Piaget. A partir das análises dos dados da pesquisa, pretende-se propor orientações para as ações pedagógicas com o uso de ambientes digitais, onde ocorram processos nos quais os sujeitos possam representar, ampliar e consolidar o seu conhecimento científico.The urgent need for changes in high school in Brazil led the researcher of this thesis to propose changes in the traditional way of working with the chemistry students.

Information management systems (digital libraries/repositories, learning management systems, content management systems) provide key technologies for the storage, preservation and dissemination of knowledge in its various forms, such as research documents, theses and dissertations, cultural heritage documents and audio files. These systems can make use of cloud computing to achieve high levels of scalability, while making services accessible to all at reasonable infrastructure costs and on-demand.
This research aims to develop techniques for building scalable digital information management systems based on efficient and on-demand use of generic grid-based technologies such as cloud computing. In particular, this study explores the use of existing cloud computing resources offered by some popular cloud computing vendors such as Amazon Web Services. This involves making use of Amazon Simple Storage Service (Amazon S3) to store large and increasing volumes of data, Amazon Elastic Compute Cloud (Amazon EC2) to provide the required computational power and Amazon SimpleDB for querying and data indexing on Amazon S3.
A proof-of-concept application comprising typical digital library services was developed and deployed in the cloud environment and evaluated for scalability when the demand for more data and services increases. The results from the evaluation show that it is possible to adopt cloud computing for digital libraries in addressing issues of massive data handling and dealing with large numbers of concurrent requests. Existing digital library systems could be migrated and deployed into the cloud.

Digital Signal Processing is playing an important role in the digital age. Most of the digital signal processing algorithms need tremendous computations. For example; Fast Fourier Transform (FFT). Convolution, Finite Impulse Response (FIR), Infinite Impulse Response (IIR), Filter, etc. All these algorithms are processing with multiplication and addition computation. We can utilize digital signal processor to compute these algorithms. There are many DSP processor, such as T1 TMS 320 series, Motorola, Analog Devices. These processors use the Harvard architecture and embed the hardware multiplier to improve the computation performance. But the whole system performance is not improved by these instruction sequential execution. In order to improve the whole system performance, we plan to use the reconfigurable logic device, such as Field Programmable Gate Array (FPGA), to design a Co-processor according to different computation algorithms. We will design many different co-processor according to each computation algorithm. The system execute each different computation by its corresponding co-processor. In this research project, we will utilize FPGA to design each different co-processor. Then we can integrate the DSP processor with these co-processors as a reconfigurable digital signal processing architecture. The whole system flexibility and performance can be improved.

This thesis consists of two major parts. The first part is the design of digital signal processor based on TMS320C542 architecture. The second part is the test of digital signal processor based on TMS320C542 architecture. In general, testing processors by way of inserting scan chains will result in hardware overhead and may cause potential performance degradation. In this work, we focus on exploring efficient functional testing methodology for solving above-mentioned problems. In functional testing, the test patterns are applied through the functional input pins and the responses are observed from the functional output pins. Therefore, the more important thing is how to produce a good test program. In this thesis, we will present a method to generate test programs and relevant analysis of the test results.

Full textAbstract:
Modern embedded systems complexity, performance and energy efficiency
has been increasing steeply the last few years. An explosive
growth in demand for wireless communication is observed as well
and modern wireless links are expected to deliver bit rates of several
gigabits while consuming even less energy.
In order to satisfy these needs new technologies emerge and novel
design approaches are put into practice. Communication at 60 GHz
is such a technology that is able to deliver high bit rates in short
range wireless links. A major motivation to use the 60 GHz spectrum
is the worldwide availability which makes exploitation economically
viable. Moreover, small wavelength of only 5 mm promises
high integration due to small antenna component size which is one
of the main bottlenecks for reducing the dimensions.
However, increased frequency comes with many disadvantages as
well. To increase the market potential of such a new technology the
chip design needs to be cheap and energy-efficient. Such cost and
energy constrains heavily impact the performance and the quality
of both the analog and the digital components of the chip.
In the current thesis the design possibilities of a component in the
digital baseband of the receiver of such a chip are explored. The
component under investigation is a Fast Fourier Transform (FFT)
that is used for frequency domain equalization. This part of the
receiver is used to reduce the effects of multipath in a non line-ofsight
communication environment and as this is a common case in
wireless communication the FFT block has been identified as one
of the 2 most computational intensive components of the receiver
in 60 GHz. This is the main reason why we explore possibilities to
further decrease the power consumption of the block while maintaining
the performance and the quality of service.
To achieve this reduction the possibilities of a new design concept
are explored. System Scenarios is a new design concept for embedded
systems operating in dynamic environments. Wireless communication
systems exhibit high dynamism during their operation on
highly varying data streams, providing the System Scenarios huge
xvi
capabilities.
The essential idea behind system scenarios is the classification of
the application under investigation from a cost perspective during
design time. Then, the classification is exploited during run time resulting
to an overall improved implementation of the application. To
achieve this the application is broken down to run-time situations
(RTS) which are distinguishable operation modes of the application.
Then RTSs with similar costs are clustered to form system scenarios.
Finally for each scenario a different mapping and scheduling of
the application is generated.
In the case of the current thesis the application is the FFT and the
cost perspective is the power consumption of the component. To exploit
the RTS clustering in run time different quantization schemes
have been produced. These schemes have been generated based on
various properties of the data waveforms in the input of the FFT.
The thesis explores the potential of the System Scenarios as well as
the application of a quantization methodology for the FFT. Different
options of the RTS clustering and the quantization of the FFT block
are evaluated in order to come up with a more efficient implementation.Τα σύγχρονα ηλεκτρονικά συστήματα παρέχουν στους χρήστες έναν καθημερινά αυξανόμενο αριθμό υπηρεσιών και λειτουργιών. Η ζήτηση τς αγοράς για ϕθηνές, αξιόπιστες και ϕορητές ηλεκτρονικές συ- σκευές ωθεί τα όρια του σχεδιασμού των ενσωματωμένων συστημάτων σε νέες ανεξερεύνητες περιοχές. Η ϕορητότητα απαιτεί την αϕαίρεση όλων των καλωδίων είτε για μετάδοση δεδομένων είτε για ενέργεια. Για να επιτευχθεί αυτό, η ασύρματη επικοινωνία σε υψηλό ρυθμό μετάδοσης είναι επιθυμητή χωρίς να θυσιαστεί η υψηλή ενεργειακή απο- δοτικότητα που καθιστά την συσκευή αυτόνομη από το ενεργειακό δίκτυο για μεγάλες χρονικές περιόδους. Η συνεχής αύξηση στις προδιαγραϕές των σύγχρονων ενσωματομένων συστημάτων έχει οδηγήσει στην χρήση καινοτόμων ιδεών, προσεγγίσεων και τεχνολογιών. Μια νέα τεχνολογία που υπόσχεται υψηλή ολοκλήρωση και υψηλό ρυθμό μετάδοσης δεδομένων στις ασύρματες ζεύξεις είναι η επικοινωνία στα 60 GHz. Μια νέα προσέγγιση σχεδιασμού για ενσωματομένα συστήματα υπόσχεται αποτελεσματική εκμετάλευση του δυναμισμού που μπορεί να παρουσιάζει ένα σύστημα. Τα ασύρματα συστήματα επικοινωνίας λειτουργούν τυπικά σε πολύ δυναμικά περιβάλλοντα. Τα Σενάρια συστήματος έχουν μεγάλες δυνατότητες για να βελτιώσουν την αποτελεσματικότητα της υλοποίησης των ψηϕιακών βάσεων τέτοιων συστημάτων. Στην παρούσα διπλωματική εξερευνούμε της δυνατότητες της αρχιτεκτονικής του FFT που βρίσκεται στην πλευρά του δέκτη ενός πομποδέκτη στα 60 GHz. Ο FFT είναι μέρος της εξίσωσης στο πεδίο της συχνότητας που χρησιμοποιείται για να μειώσει της επιδράσεις του ϕαινομένου multipath. Χρησιμοποιώντας Σενάρια Συστήματος προσπαθούμε να καταλήξουμε με μια πιο προσαρμοστική και συνεπώς πιο ενεργειακά αποδοτική υλοποίηση του μετασχηματισμού. Η εϕαρμογή των Σεναρίων Συστήματος χρησιμοποιώντας δεδομένα ως παράμετρο είναι μια καινοτόμα προσέγγιση και σε αυτή την διπλωματική εργασία ελέγχουμε την επιτευξιμότητα της. Για να επιτύχουμε κάτι τέτοιο πρέπει να μπορούμε να παράγουμε πολλαπλά διαϕορετικά σχέδια κβαντοποίησης του μετασχηματισμού σε αποδεκτά χρονικά διαστήματα. Οι παρούσες μέθοδοι κβαντοποίησης δεν μπορούν ακόμα να παρέχουν τέτοια δυνατότητα. Έτσι βασιζόμενοι στην επέκταση μια υπάρχουσας μεθοδολογίας προτείνουμε μια ολοκληρωμένη μεθοδολογία που μπορεί να παράγει σχέδια κβαντοποίησης μεγάλων στοιχείων υλικού όπως ο FFT.

The evolution of wireless communication protocols drives the quest of power-efficient and flexible computing for embedded digital signal processors (DSPs), but the popular DSP architectures, very-long-instruction-word (VLIW) and application-specific instruction set processor (ASIP), serve as opposite extreme cases in regard to power-efficiency and flexibility. To this end, we present DeAr: Dual-thread Architecture DSP, which manipulates a multi-banked register file that enables simultaneous multi-threading (SMT), as well as a transport-triggered bus that exploits the data forwarding mechanism in its compact datapath. In addition, a novel scheduling algorithm that leverages the compact hardware to achieve both high throughput and flexible computation is presented. To go beyond a single core DSP, we also propose a system integration framework and a compilation tool for DeAr based on Heterogeneous System Architecture (HSA), which is a promising standard for the multi-core architecture promoted by several leading semiconductor companies, AMD, ARM, MediaTek, etc. In the experiment of the comparison with VLIW and ASIP respectively, DeAr either saves 20.3%–13.1% and 31.8%–2.2% of power, 36.1%–31.5% and 28.2%–5.7% of area in the benchmark suite aiming at wireless communication, or saves 20.3%–13.1% and 31.8%–2.2% of power, 36.1%–31.5% and 28.2%–5.7% of area in the benchmark suite of general digital signal processing kernels.

Emerging applications such as high definition television (HDTV), streaming video, image processing in embedded applications and signal processing in high-speed wireless communications are driving a need for high performance digital signal processors (DSPs) with real-time processing. This class of applications demonstrates significant data parallelism, finite precision, need for power-efficiency and the need for 100's of arithmetic units in the DSP to meet real-time requirements. Data-parallel DSPs meet these requirements by employing clusters of functional units, enabling 100's of computations every clock cycle. These DSPs exploit instruction level parallelism and subword parallelism within clusters, similar to a traditional VLIW (Very Long Instruction Word) DSP, and exploit data parallelism across clusters, similar to vector processors.
Stream processors are data-parallel DSPs that use a bandwidth hierarchy to support dataflow to 100's of arithmetic units and are used for evaluating the contributions of this thesis. Different software realizations of the dataflow in the algorithms can affect the performance of stream processors by greater than an order-of-magnitude. The thesis first presents the design of signal processing algorithms that map efficiently on stream processors by parallelizing the algorithms and by re-ordering the flow of data. The design space for stream processors also exhibits trade-offs between arithmetic units per cluster, clusters and the clock frequency to meet the real-time requirements of a given application. This thesis provides a design space exploration tool for stream processors that meets real-time requirements while minimizing power consumption. The presented exploration methodology rapidly searches this design space at compile time to minimize power consumption and selects the number of adders, multipliers, clusters and the real-time clock frequency in the processor. Finally, the thesis improves the power efficiency in the designed stream processor by adapting the compute resources to run-time variations in the workload. The thesis presents an adaptive multiplexer network that allows the number of active clusters to be varied during run-time by turning off unused clusters. Thus, by efficient mapping of algorithms, exploring the architecture design space, and by compute resource adaptation, this thesis improves power efficiency in stream processors and enhances their suitability for high performance, power-aware, signal processing applications.

In this thesis, a digital signal processor that is designed for communication appli-cations with a programmable correlator array architecture is introduced. The pro-grammable correlator can be easily configured as a chip match filter, code group detector, scrambling code detector, and RAKE receiver. It also has low power consideration. The architecture and instruction set of the proposed DSP (CDSP) makes it has good performance at Viterbi algorithm and complex arithmetic operations for some wireless communication standards such as GSM and IS-95. According to the performance evaulation results, the suggested DSP core outperforms other DSPs in terms of several operations normally used in wireless communication. The chip was implemented in a hybrid design method where the critical path was full-custom designed and the other parts are cell-based using a 0.35um 1P4M cell-library. We believe that the suggested correlator array architecture and digital signal processor are useful for future 3G mobile terminal design.
