Résumé :

International Telemetering Conference Proceedings / October 28-31, 1985 / Riviera Hotel, Las Vegas, Nevada
A generic software architecture has been developed to support the typical functionality required of the host computer in a telemetry ground station system. The architecture provides sufficient flexibility to permit support of the wide spectrum of requirements typically placed on such systems, while at the same time providing a structural shell which helps to minimize the complexity of applications software. The general issues addressed by this architecture include: - The need to interface to a wide variety of telemetry front end equipments. - The need to provide a convenient consistent, and efficient operator interface to the integrated telemetry system. - The need to support a variable amount and wide range of applications specific processing. - The need to be adaptable across different sizes of host computers. - The need to be adaptable across different host computer systems. This paper defines, at a high level, the architecture that has been defined and the general data structure concepts required to make it work. It further addresses the standardized operator interface supported by the architecture and finally, summarizes the benefits that have been demonstrated to be derived through the use of this standardized approach in the development of telemetry host computer software.

International Telemetering Conference Proceedings / October 28-31, 1985 / Riviera Hotel, Las Vegas, Nevada
The paper surveys the particular problems, arising in the architectural design of computing systems, realized on VLSI chips. Particular difficulties due to limited on-chip density and power dissipation are discussed. The difficulties of the realization of on-chip communications between various subsystems (between themselves and between other offchip systems) are stressed. A number of design principles for the realization of on-chip communication paths is presented. Two design philosophies for the instruction set design in a VLSI environment are brought up: (a) The large microcoded instruction set, (b) The Reduced Instruction Set Computer (RISC) approach, based on the Streamlined Instruction Set Design. A survey of the author’s research group work in this area is presented. This includes the ZT-1 single chip microcomputer, RISC computing space studies, applications to a distributed traffic control and a la rge scale, reconfigurable communications system.

Odhiambo, Marcel O. « HYDRA : parallel and distributed Swarm computer architecture ». Thesis, University of Surrey, 1998. http://epubs.surrey.ac.uk/843654/.

Texte intégral

Résumé :

The research in computer architecture for agent-based parallel and distributed processing was prompted by the interest and the related ongoing work in agent-based computing. Agent-based computing best suits the Internet (a collection of computers interconnected by high speed communication links) in which every computer or host is an entity. Agents enable the user to search the internet offline as compared to online. The user is freed to attend to task requiring the user's intervention and the user only logs to the network to check the results returned by the agent. A number of agent-based systems have been implemented. The TACOMA, Telescript and WAVE are based on an interpreted engine (program code) running in the background, accepting and interpreting the user inputs. The Swarm system on the other hand, is based on compiled program code which is stored at each host. The agent navigate the network based on destination address (PM address in Swarm, another agent in TACOMA, a place in Telescript or a node address in WAVE). In the interpreted program based systems, the agent carries with it the code to be executed at the reached destination, while in the Swarm system, the agent carries the instruction pointer, pointing to the next instruction to be executed at the reached destination. HYDRA; A Parallel and Distributed Swarm computer architecture for agent processing is based on a single user Swarm computer architecture prototype developed and simulated on a single host by [Errico 1996]. Agents are self contained executable mobile processes that navigate a network of hosts using hosts' addresses, executing a task, and when the task terminates, the outcome of the task execution is sent to the user. Swarm consists of three modules: the AP (Access Point) through which the user can access the Swarm computer to run tasks, the RM (Routing Module), responsible for routing the agents in the Swarm computer, and the PM (Processing Module), which is the execution engine in the Swarm computer. A PM is the destination of an executing agent. The aim of the thesis was to simulate the Swarm computer architecture in a distributed environment, where the PMs are distributed among several hosts in the network. The distributed environment consists of a few or several hosts connected together by an interconnection network. Hosts on the network are grouped into domains, and the domains are interconnected together to form a network. Hosts in a domain are directly connected to every other host within that domain. Within a domain, a single host acts as a gateway host handling extra-domain agents. To enable me achieve my goal, I designed, implemented and tested a Communication Router (CR). The CR consists of Network Router (NR) and the Routing Module (RM). The CR has two main functions: 1. Provide connectivity among the hosts in the network. 2. Route agents between the hosts. To be able to connect host on the network and to route agents between them, I developed a connection algorithm, and a routing algorithm. The connection algorithm logically connects hosts in the same domain, builds a routing table at each host, and identifies a gateway host for each domain. The routing algorithm, using the routing table at each host ensures delivery of agents to their proper destinations, irrespective of the location of the Processing Module. Simulation tests were carried on the the HYDRA computer prototype, and the preliminary test results obtained do show that the connection, and routing algorithms were respectively able to connect the hosts, and to route agents between the hosts. And, that agents and the HYDRA computer architecture could be used to do some useful work. In this thesis I present the HYDRA computer architecture, the work done in the design, and implementation of the Network Router, Routing Module, Access Point, the connection algorithm, the routing table, the agent routing algorithm, the communication strategy adopted for routing messages in the network, the simulation tests carried out, and the test results obtained.

Jäger, Nils. « Enacted embodiment in adaptive architecture : physiological interactions between inhabitants and biofeedback architecture ». Thesis, University of Nottingham, 2015. http://eprints.nottingham.ac.uk/30854/.

Texte intégral

Résumé :

This thesis argues for an enactive embodied approach to understanding in- teractions with Adaptive Architecture. The growing interest in Ubiquitous and Pervasive Computing, including the current trends of wearable, sensor infused technology, shows the inevitable confluence of Human-Computer Interaction (HCI) and Architecture. Specifi- cally, the availability of real-time physiological data allows environments to respond directly to the bodily behaviours of their users. This creates an in- teraction cycle or loop, which temporarily couples architectural environ- ment and human body. One instantiation of such an interaction loop are so called biofeedback environments, which reflect an inhabitant's physiological behaviour back to the inhabitant. Very few such environments exist, little empirical research has been done regarding their effects on inhabitants, and none have specifically engaged with, appropriated, and discussed the concept of enacted embodiment in this context so far, especially regarding multi-occupancy. To investigate enacted embodied interactions with adaptive environments I use a three-tiered, mixed-method approach. In an in-depth, quantitative study of an existing prototype (ExoBuilding) I first investigated the enacted control-relationship between environment and an individual inhabitant. I found that, by manipulating the control relationship between the biofeed- back environment and its occupant, the environment can actively influence the physiological behaviour of its inhabitant, which in this case was respira- tion rate. The reasons why participants changed their behaviour after having lost practical control over the interaction were found to either be a pre- cognitive bodily interaction with the environment or to be an intentional synchronising with the changing environment in order to maintain cognitive control of the situation. Secondly, these findings and interpretations lead to a research-based design of a new multi-inhabitant prototype environment allowing enacted embod- ied interactions between the inhabitants themselves and between them and the environment called WABI. While expandable, WABI currently envelopes two sections, each of which accommodates one inhabitant. Through further co-development of the software platform originally used for ExoBuilding, WABI can distribute biofeedback spatially to both its building sections in multiple ways. Thirdly, I investigated the effects of three feedback distribution modes on the two inhabitants of WABI in a qualitative exploratory study, which found that physiological synchrony is highest when the environment distributes real- time feedback such that participants are surrounded by their partner's phys- iology. I propose a model of triadic enacted embodiment that conceptualises the observed interactions between inhabitants and between them and WABI. This work makes three key contributions to HCI and Architecture. First, it provides empirical data to the limited existing knowledge of the effects of adaptive environments on their inhabitants. Specifically, it increases our un- derstanding of the control relationship between inhabitant and adaptive en- vironment. And for the first time it provides an insight into interpersonal physiological synchrony between inhabitants of adaptive environments. Sec- ondly, this work adds a new class of adaptive environment that enables shared biofeedback between its inhabitants. And thirdly, the previous two contributions expand the existing concepts of embodiment, which so far have ignored the bodily relationship between inhabitants and adaptive envi- ronments.

Texte intégral

Résumé :

The computational requirements for real-time image based applications are such as to warrant the use of a parallel architecture. Commonly used parallel architectures conform to the classifications of Single Instruction Multiple Data (SIMD), or Multiple Instruction Multiple Data (MIMD). Each class of architecture has its advantages and dis-advantages. For example, SIMD architectures can be used on data-parallel problems, such as the processing of an image. Whereas MIMD architectures are more flexible and better suited to general purpose computing. Both types of processing are typically required for the analysis of the contents of an image. This thesis describes a novel massively parallel heterogeneous architecture, implemented as the Warwick Pyramid Machine. Both SIMD and MIMD processor types are combined within this architecture. Furthermore, the SIMD array is partitioned, into smaller SIMD sub-arrays, forming a Multiple-SIMD array. Thus, local data parallel, global data parallel, and control parallel processing are supported. After describing the present options available in the design of massively parallel machines and the nature of the image analysis problem, the architecture of the Warwick Pyramid Machine is described in some detail. The performance of this architecture is then analysed, both in terms of peak available computational power and in terms of representative applications in image analysis and numerical computation. Two tracking applications are also analysed to show the performance of this architecture. In addition, they illustrate the possible partitioning of applications between the SIMD and MIMD processor arrays. Load-balancing techniques are then described which have the potential to increase the utilisation of the Warwick Pyramid Machine at run-time. These include mapping techniques for image regions across the Multiple-SIMD arrays, and for the compression of sparse data. It is envisaged that these techniques may be found useful in other parallel systems.

A digital paint package has been developed which places attention on the design of personal "brush " patterns. The user generates an image by iterating these pattern modules on the raster display. During the application of a pattern, it can grow, shrink, and change in opacity level under the user's control. This method of digitally creating images was developed in light of the problem of representing visual characteristics effectively while "painting" with a computer graphics system . Allowing the user to design personal brush patterns, which can be stored in a library of patterns, and to make marks by repeating them, expands the potential visual qualities of the image as demonstrated by sample images included in this thesis. Software functions are provided for creating and editing patterns through a menu of selections. These functions treat individual shapes and colors in a pattern as separate entities that can be manipulated. Shapes can be manipulated individually, or as a selected group. The manipulation functions include the following: move, copy, scale, and delete. Software functions are also provided for the editing of color components. One method allows a color's red, green, and blue components to be adjusted. And the other allows its hue, lightness, and saturation levels to be adjusted.

Résumé :

In this study, the architecture and evolution of computer game engines are analyzed by means of a literature review on the academic research body on the subject. The history of computer games, from early 1960s to modern day is presented, with a focus on the architectures behind the games. In the process, this study will answer a selection of research questions. The topics of the questions include identifying the common parts of a game engine, identifying the architectural trends in the evolution from early to present-day games and engines, identifying ways the process of evolution has affected the present state of the engines, and presenting some possible future trends for the evolution. As findings of the study, common parts of a game engine were identified as the parts that are specific to every game, with the suggestion that more detailed analyses could be made by concentrating on different genres. Increase in the size, modularity and portability of game engines, and improved tooling associated with them were identified as general trends in the evolution from first games to today. Various successful design decisions behind certain influential games were identified, and the way they affect the present state of the engines were discussed. Finally, increased utilization of parallelism, and the move of game engines from genre-specific towards genre-neutral were identified as possible future trends in the evolution.

Texte intégral

Résumé :

The root system of a plant is responsible for supplying it with essential nutrients. The plant's ability to explore the surrounding soil is largely determined by its root system architecture (RSA), which varies with both genetic and environmental conditions. X-ray micro computed tomography (µCT) is a powerful tool allowing the non-invasive study of the root system architecture of plants grown in natural soil environments, providing both 3D descriptions of root architecture and the ability to make multiple measurements over a period of time. Once volumetric µCT data is acquired, the root system must first be segmented from the surrounding soil environment and then described. Automated and semi-automated software tools can be used to extract roots from µCT images, but current methods for the recovery of RSA traits from the resulting volumetric descriptions are somewhat limited. This thesis presents a novel tool (RooTh) which, given a segmented µCT image, skeletonises the root system and quantifies global and local root traits with minimal user interaction. The computationally inexpensive method used takes advantage of curve-fitting and active contours to find the optimal skeleton and thus evaluate root traits objectively. A small-scale experiment was conducted to validate and compare root traits extracted using the method presented here alongside other 2D imaging tools. The results show a good degree of correlation between the two methods.

Résumé :

Real time image understanding and image generation require very large amounts of computing power. A possible way to meet these requirements is to make use of the power available from parallel computing systems. However parallel machines exhibit performance which is highly dependent on the algorithms being executed. Both image understanding and image generation involve the use of a wide variety of algorithms. A parallel machine suited to some of these algorithms may be unsuited to others. This thesis describes a novel heterogeneous parallel architecture optimised for image based applications. It achieves its performance by combining two different forms of parallel architecture, namely fine grain SIMD and course grain MIMD, into a single architecture. In this way it is possible to match the most appropriate computing resource to each algorithm in a given application. As important as the architecture itself is a method for programming it. This thesis describes a novel multi-paradigm programming language based on C++, which allows programs which make use of both control and data parallelism to be expressed in a single coherent framework, based on object oriented programming. To demonstrate the utility of both the architecture and the programming system, two applications, one from the field of image understanding the other image generation are examined. These applications combine some novel algorithms with other novel implementation approaches to provide the most effective mapping onto this architecture.

Texte intégral

Résumé :

In this thesis existing models of adaptive computer architecture were modified to adapt actual sorting problems to "divide 'n' conquer" (DQ) coordinator type configuration in which the children processors were expanded from three to four. Two hire/fire strategies, one using packets waiting in queue and the other using the average turn around time, were applied to maintain the hierarchical tree structure. More than 1200 simulation runs were analyzed and compared, finding that the first strategy was best at fast packet arrival rate and the second strategy was best at slow packets arrival rate. Comparing the hire/fire signal generation policies, the "fc-root" was best and the "root-fp" was worst. While comparing the effect of variable weighting factors in processors, using smaller weighting factor in either "partitioner" for the first strategy or "f-computer" for the second strategy may improve the system performance.

Texte intégral

Résumé :

This thesis presents Harmony Oriented Architecture: a novel architectural paradigm that applies the principles of Harmony Oriented Programming to the architecture of scalable and evolvable distributed systems. It is motivated by research on Ultra Large Scale systems that has revealed inherent limitations in human ability to design large-scale software systems that can only be overcome through radical alternatives to traditional object-oriented software engineering practice that simplifies the construction of highly scalable and evolvable system. HOP eschews encapsulation and information hiding, the core principles of object-oriented design, in favor of exposure and information sharing through a spatial abstraction. This helps to avoid the brittle interface dependencies that impede the evolution of object-oriented software. HOA extends these concepts to distributed systems resulting in an architecture in which application components are represented by objects in a spatial database and executed in strict isolation using an embedded application server. Application components store their state entirely in the database and interact solely by diffusing data into a space for proximate components to observe. This architecture provides a high degree of decoupling, isolation, and state exposure allowing highly scalable and evolvable applications to be built. A proof-of-concept prototype of a non-distributed HOA middleware platform supporting JavaScript application components is implemented and evaluated. Results show remarkably good performance considering that little effort was made to optimize the implementation.

I present a novel drawing system for composing and rendering perspective scenes. The proposed approach uses a projective two-dimensional representation for primitives rather than a conventional three-dimensional description. This representation is based on points that lie on the surface of a unit sphere centered at the viewpoint. It allows drawings to be composed with the same ease as traditional illustrations, while providing many of the advantages of a three-dimensional model. I describe a range of user-interface tools and interaction techniques that give the drawing system its three-dimensional-like capabilities. The system provides vanishing point guides and perspective grids to aid in drawing freehand strokes and composing perspective scenes. The system also has tools for intuitive navigation of a virtual camera, as well as methods for manipulating drawn primitives so that they appear to undergo three-dimensional translations and rotations. The new representation also supports automatic shading of primitives using either realistic or non-photorealistic styles. My system supports drawing and shading of extrusion surfaces with automatic hidden surface removal and emphasized silhouettes. Casting shadows from an infinite light source is also possible with minimal user intervention. I describe a method for aligning a sketch drawn outside the system using its vanishing points, allowing the integration of computer sketching and freehand sketching on paper in an iterative manner. Photographs and scanned drawings are applied to drawing primitives using conventional texture-mapping techniques, thereby enriching drawings and providing another way of incorporating hand-drawn images. I demonstrate the system with a variety of drawings.

The influence of the computer is increasing within the architectural profession. One aspect of this is the growing use of microcomputer programs in architectural education. Many of these programs have their roots in the engineering disciplines, and therefore their procedural methodology may no t be compatible with the architectural design process. In addition to this, most of the programs used in the universities are originally designed for the professional practitioner, and may not be appropriate for the academic environment This discussion explores the characteristics of the architectural design process, and what issues programmers need to address when writing software for use by designers. More specifically, how should the programmer approach designing educational software, so that the computer becomes a more effective tool in enabling the student to develop heuristic knowledge about some aspect of architectural design. The programming factors that influence the effectiveness of this type of educational software include: the appropriate use of graphics, flexible input/output sequences, procedural transparency of the program structure, and the iterative comparison of design options. These concepts are analyzed in a series of programming examples involving energy analysis and daylighting analysis. Existing programs are critiqued, and suggestions for improvements are made. The use of processors to facilitate the testing and comparison of results are presented, as well as guidelines for additional developments using knowledge base overlays.

Résumé :

The art of structural design lies in the selection of the most suitable structural system for a given structure. The arrangement of beams, girders, trusses and columns to support gravity design loads determines the economy and functional suitability of a building. Much of the cost of a steel framed building is in the floor system. Due to the lack of suitable optimization schemes, numerous trial designs might be necessary to ensure that the most economical system has been selected. Therefore, a computer program is developed as a design aid to make such studies practical in a design office. The program, developed on a mini-computer, is capable of designing structural components of steel framed buildings. These components include gravity columns and floor framing members such as simply supported beams and girders, cantilevers, beams and girders with overhangs, trusses and stub-girders. The program is based on the requirements of CSA Standard CAN3-S16.1-M78, "Steel Structures for Buildings-Limit States Design". In addition to its ability to select steel sections, quantity take-off and cost estimates features are incorporated in the program.

Résumé :

The exponential downscaling of the feature size has enforced a paradigm shift from computation-based design to communication-based design in system on chip development. Buses, the traditional communication architecture in systems on chip, are incapable of addressing the increasing bandwidth requirements of future large systems. Networks on chip have emerged as an interconnection architecture offering unique solutions to the technological and design issues related to communication in future systems on chip. The transition from buses as a shared medium to networks on chip as a segmented medium has given rise to new challenges in system on chip realm. By leveraging the shared nature of the communication medium, buses have been highly efficient in delivering multicast communication. The segmented nature of networks, however, inhibits the multicast messages to be delivered as efficiently by networks on chip. Relying on extensive research on multicast communication in parallel computers, several network on chip architectures have offered mechanisms to perform the operation, while conforming to resource constraints of the network on chip paradigm. Multicast communication in majority of these networks on chip is implemented by establishing a connection between source and all multicast destinations before the message transmission commences. Establishing the connections incurs an overhead and, therefore, is not desirable; in particular in latency sensitive services such as cache coherence. To address high performance multicast communication, this research presents Quarc, a novel network on chip architecture. The Quarc architecture targets an area-efficient, low power, high performance implementation. The thesis covers a detailed representation of the building blocks of the architecture, including topology, router and network interface. The cost and performance comparison of the Quarc architecture against other network on chip architectures reveals that the Quarc architecture is a highly efficient architecture. Moreover, the thesis introduces novel performance models of complex traffic patterns, including multicast and quality of service-aware communication.

Résumé :

Multimedia systems applications have become major research interests in both computing and telecommunications industries. In some literature, multimedia is defined as "mant media" where media is derived from medium, and a medium is a means of transporting information. It is generally accepted that multimedia does enhance communication for individuals and among interacting groups of humans. Applications such as video conferencing, distance learning, and medical imaging, gain advantage in the use of multimedia applications. However, while it is recognised that future systems should provide multimedia functionality, many issues are being raised about how best to support multimedia communication. This is because multimedia requires new communications infrastructures to enable integration of various media types as well as to manipulate and control the individual media. There is also the need to support the spatial and temporal requirements of continuous media, and to support group based applications. Thus the requirements of multimedia applications are diverse; this thesis focuses on multimedia group management services. A number of architectures have been advanced on the management strategies for multimedia communications. A review of these architectures shows that they have been either application specific, or too restrictive for group based applications. This thesis presents an architecture for connection management for distributed multimedia group applications. The architecture is intended to encourage a uniform appearance to all group applications to assist in their collective management, whilst being sufficiently flexible to cope with all likely multicast mechanisms upon which such applications may be based. The concept of a media channel is introduced as the application-independent appearance of an instance of a single applications such as a video-on-demand service, or a video conferencing application. A media channel is the basic unit of management in a group user-agent and therefore is used as a basis for the management of multiple applications. The main aspects of the media channel model considered in the thesis have been substantially implemented and the performance accessed as suitable for a reasonable number of multimedia applications.
