Full textInternet of Things (IoT) is becoming more common in today's society. More and more everyday devices are connected to the wireless network. This requires costeffective computing power, which means that it can be beneficial to investigate the microcontroller and how they would cope with this task. These can be seen as smaller compact computers which despite their size offer a lot of performance. This study aims to inform if any existing operating system can work together with the microcontroller PIC18F452 and how many processes that can run in parallel given the MCU's limited memory. A survey and an experiment were conducted to answer these questions. Different choice of methods was investigated and discussed to determine which method would generate the best results. A survey and an experiment were conducted to answer these questions. The experiments required a special development environment to be installed and the generic FreeRTOS distribution was ported to both the correct processor and the experimental card. The porting succeeded and experiments showed that the research question could be answered with a yes. You can run a real-time operating system on an MCU with only 1,5 kB RAM memory. During the work, the project also found that Amazon built its IoT on FreeRTOS. However, they had invested in a more powerful MCU. The effort would thus emphasize it as a more future-proof approach.

Full textIdag är effekten av de vanligaste åtgärderna för att förbättra prestandan av inbyggda system och realtidsoperativsystem väldigt liten. På grund av detta är det intressant att undersöka nya åtgärder för att tänja prestandagränserna av inbyggda system och realtidsoperativsystem ytterliggare. Det har tidigare påvisats att det hårdvarubaseraderealtidsoperativsystemet, Sierra, har bättre prestanda än det mjukvarubaseraderealtidsoperativsystemet, FreeRTOS. Dessa realtidsoperativsystem har även visats vara lika i flera aspekter, vilket betyder att det är möjligt för Sierra att accelererera FreeRTOS. I detta examensarbete har en implementering av en sådan acceleration genomförts. Eftersom befintliga realtidsoperativsystem ständigtär i utveckling i kombination med att det är flera år sedan som en tidigare jämförelse mellan de båda systemen utfördes, så jämfördes FreeRTOS och Sierra i fråga om funktionalitet och uppbyggnad även i detta examensarbete.Denna jämförelse visade att FreeRTOS och Sierra delar de mest grundläggande funktionerna av ett realtidsoperativsystem, och som därmed kan accelereras av Sierra, men att FreeRTOS även har ett antal exklusiva funktioner för att underlätta användningen av det realtidsoperativsystemet. Informationen som erhölls av denna jämförelse var sedan grunden för hur själva accelerationen skulle implementeras. Efter ett antal prestandatesterkunde det konstateras att alla implementerade funktioner, med undantag för ett fåtal, hade kortare exekveringstid än motsvarande funktioner i ursprungsversionen av FreeRTOS.

Full textMånga inbyggda system saknar en enhet för minneshantering (s.k. MMU) och saknar därför oftast minnesskydd. Detta leder till att dessa system blir mindre robusta eftersom operativsystemet, processer och trådar inte längre är isolerade från varandra. Detta är också en säkerhetsbrist och med antalet inbyggda system som snabbt ökar på grund av tillväxten av Internet of things (IoT), så kan sårbarheter som denna bli ett stort problem. Med en nyligen introducerad uppdatering av RISC-Vprocessor arkitekturen, så introducerades en möjlighet till att isolera minne utan hjälp av en MMU. Denna studie syftar till att identifiera problem och möjligheter av att implementera sådant minneskydd med RISC-V. Baserat på en studie av litteratur och dokumentation om minnesskydd och RISC-V arkitekturen designades och implementerades en prototyp för att hjälpa till att fastställa problem och möjligheter samt göra en utvärdering med avseende på prestanda- och minneskostnader. Den utvecklade prototypen visade en fungerande implementering av minneskydd för minnesregioner med RISC-V. Utvärderingen av prototypen visade en ökad exekveringstid för kontextbyten och ökad minnesanvändning. Resultaten indikerar att det implementerade minneskyddet kommer med en ökad kostnad i prestanda med en konstant faktor och en liten omkostnad i minne. Därför rekommenderas att implementeringar som vill implementera minneskydd med RISC-V på mindre inbyggda system där tid och minne kan vara avgörande tar hänsyn till omkostnaderna. Ytterligare studier och tester behövs för att identifiera optimeringar som kan förbättra prestandan och upptäcka säkerhetsbrister.

Este documento apresenta a utilização de diferentes modos de economia de energia aplicados em sistemas operacionais de tempo real, quando o mesmo não possui tarefas a serem executadas. Espera-se que, ao entrar em modos de baixo consumo oferecidos pelo próprio microcontrolador, haja uma diminuição no consumo de energia, proporcional ao número de módulos internos que são desativados. Entretanto, a economia pode não se mostrar válida de acordo com a carga de processamento que o sistema possui, pois a corrente instantânea consumida após a transição do estado de baixo consumo para o modo ativo é superior ao consumo do sistema em operação constante. Desta forma, será apresentada uma política de economia de energia e como aplicá-la, simultaneamente minimizando a carga energética e balanceando a exigência de processamento.

Full textLa stimulation magnétique transcrânienne répétée (SMTr) a été utilisée pour traiter les maladies neurologiques ainsi que pour comprendre la relation entre le cerveau et le comportement. Toutefois, les effets sous-jacents de la SMTr au niveau neuronal n'ont pas été suffisamment étudiés pour corroborer les résultats d'expériences comportementales SMT chez les humains. Nous avons enregistré les spikes et les potentiels de champs locaux de l'aire corticale visuelle 18 de chats anesthésiés et paralysés, à l'aide d'une multi-électrode 10x10 avant et après l'application de la SMTr. En utilisant les SMTr de 4Hz et de 20Hz, nous avons prouvé qu'au niveau neuronal à la fois les SMT basse et haute fréquences provoquent la suppression significative de l'activité évoquée. Nous avons également utilisé les courbes de sélectivité à l'orientation de multiples aires corticales comme un reflet du comportement afin de tester si les effets de la SMTr étaient dépendants de l'état d'activation du cerveau. Les SMT-conditionnée et non-conditionnée ont toutes les deux causé la suppression des courbes de sélectivité des neurones. Un état cortical activé a été obtenu par des impulsions de SMTr conditionnée avec un stimulus visuel. Nous avons observé que le changement provoqué par la SMTr sur la sélectivité des neurones allait dans la même direction que le cortex soit ou non dans un état activé lorsque la SMT est appliquée. Bien qu'il y ait une tendance à une différence entre les niveaux de suppression et entre les changements dans les propriétés de sélectivité, cette différence n'était statistiquement significative dans aucun des paradigmes testés dans cette étude.

Full textEmwiro Vibe is a complete system for seismic measurements. The functionality of the system was before the completion of this project handled using a software contruction based on a state machine. Emwitech, the company developing Emwiro Vibe, expressed a desire to replace this solution with a real-time operating system (RTOS). The project consisted of two parts. Firstly the existing software was studied, available RTOSes was evaluated, and the RTOS most suitable for the application was selected. Secondly the systems software was rewritten to make use of the selected RTOS. The conclusion made from the evaluation, taking into consideration existing requirements, was that FreeRTOS was the most appropriate RTOS for this application. The systems software was successfully modified to make use of the benefits provided using a RTOS. Despite the introduction of a RTOS in the system, the power consumption did not increase considerably, it was even reduced i certain cases.

Full textOver the last 3 years the Naval Air Warfare Center Aircraft Division (NAWCAD), Patuxent River, MD, has been in the process of developing a link between its secure Manned Flight Simulator (MFS) and Real Time Processing System (RTPS) facilities. The MFS hosts a wide variety of high fidelity fixed and rotary wing aircraft simulation models. The RTPS is used as a telemetry ground station for conduct of Navy flight testing at Patuxent River MD. The ability to integrate simulation with flight testing in a real time environment provides new potential for increased flight safety, enhanced engineering training, optimized flight test planning, real time simulation fidelity assessments, improved engineering analysis and other applications for enhanced flight testing, data analysis and data processing. A prototype system has been successfully designed and operated at NAWCAD in support of an F/A-18C flight test project which required simultaneous merging and display of real time and simulation data to reduce the risk of departure from controlled flight. As currently designed the link (encryption and decryption gear in the loop) can be operated in three modes: (1) Simulation sending data to RTPS (e.g. pilot-engineer pre-first flight preparation/training scenario, (2) simulation is driven by real aircraft control surface inputs and response is compared with that of the real aircraft for simulation fidelity assessments and (3) simulation "rides along" with the real aircraft and data are extracted from the simulation which are otherwise unavailable from the aircraft (e.g. flight control law interconnect signals, control law feedback signals, aerodynamic data, propulsion model data, avionics model data, other model data etc.). This paper discusses, design and implementation aspects of the RTPS-Simulator link, and includes a description of how the link was used to support a real time flight test program by providing critical safety of flight data. Other potential uses for the link will also be highlighted.

Full textSistemas embarcados estão cada vez mais presentes em nossas vidas e estão se tornando onipresentes. Este fato tem demandado grandes esforços em pesquisa para criação de propostas e soluções para os desafios gerados no desenvolvimento destes sistemas. Por exemplo, uma arquitetura moderna de sistemas embarcados requer alto poder de computação e também grande exibilidade, e a demanda por estes requisitos tem crescido constantemente. Uma única arquitetura deve executar, em certos casos, diferentes aplicações com diferentes requisitos e com inicio de execução indeterminado, caracterizando desta maneira um ambiente dinâmico. A computação reconfigurável aparece como um paradigma promissor para estes casos pois consegue prover alto poder de computação juntamente com exibilidade requeridas pelos sistemas embarcados modernos. Especialmente interessantes são arquiteturas baseadas em System-on-Chip reconfiguráveis (RSoC), nas quais um microprocessador está fortemente conectado a um hardware reconfigurável (plataforma híbrida). Porém a complexidade no desenvolvimento destes tipos de sistemas cresce, tornando o uso de um sistema operacional (SO) indispensável. Entretanto, uma plataforma de execução de um sistema embarcado sofre pela escassez de recursos. Este fato exige um cuidado especial no desenvolvimento de um SO uma vez que este também usa os recursos desta plataforma. Juntamente com as tarefas da aplicação, o SO também pode tirar proveito de uma plataforma baseada em RSoC onde este é capaz de se auto reconfigurar sobre esta plataforma híbrida. Deste modo, o SO pode usar os recursos computacionais, correntemente não requeridos pelas aplicações, para a sua execução. Dentro deste contexto, este trabalho apresenta o design de metodologias, estratégias e suporte em hardware e software para o gerenciamento apropriado das atividades de reconfigurações dinâmicas de um sistema operacional de tempo-real (RTOS), que é executado em uma plataforma baseada em RSoC. A intenção com isto é a de proporcionar ao RTOS meios com os quais este é capaz de se auto reconfigurar nesta arquitetura híbrida com a intenção de atingir um uso mais eficiente dos recursos computacionais desta plataforma de execução.
Embedded systems are massively present in our lives and they are becoming omnipresent. This has demanded strong e orts in research for providing new solutions for the challenges faced in the design of such systems. For instance, the requirements of high computational performance and exibility of the contemporary embedded systems are continuously increasing. A single architecture must be able to support, in certain cases, di erent kind of applications with di erent requirements which can start asynchronously and dynamically (changing environments). Recon gurable computing seems to be a potential paradigm for these scenarios as it can provide exibility and high computational performance for modern embedded systems. Of especial interest are those architectures where a microprocessor is tightly connected with a recon gurable hardware (hybrid platform), constituting a so called recon gurable System-on-Chip (RSoC). However, the complexity in designing such systems rises. Therefore, the usage of an Operating System (OS) is essential to provide the necessary abstraction of the computational resources in recon gurable computing. Moreover, due to the intrinsic overhead caused by the recon guration activities and the potential sharing of computational resources the necessity for support provided by an OS is unquestionable. Nevertheless, embedded system platforms lack in computational resources. This fact requires a careful design of an OS for such a system, since it also consumes its resources. Along with the application tasks, the OS can pro t from a RSoC based architecture by recon guring itself over this hybrid platform. Thereby, the OS can make use of the remaining resources that are not currently required by the application for its execution. Within this context, this work presents the design of proper methodologies, strategies, hardware and design support for a proper management of dynamic recon guration activities of a Real-Time Operating System (RTOS) running on a RSoC based platform. The intention thereby, is to promote the self-recon guration of the RTOS services on this hybrid platform, so that the computational resources of this execution platform are used in an e cient way.

Resumo: Devido à dificuldade de execução de testes em sistemas reais os engenheiros procuram ferramentas e modelos para simular ou emular os sistemas reais em laboratório. Nesse sentido, o objetivo deste projeto de pesquisa foi desenvolver um modelo do relé de proteção diferencial de transformador no simulador digital em tempo real RTDS, baseando-se no relé SEL-787 da Schweitzer Engineering Laboratories Inc. O objetivo de criar um relé específico e já existente no mercado, saindo dos modelos genéricos, é devido à necessidade dos estudos em laboratório apresentarem resultados concretos e que representem o sistema real, desta forma apresentará grande valia para as futuras expansões do Sistema Elétrico Nacional ou Internacional. Após o desenvolvimento do modelo matemático do relé, foram criadas rotinas de teste exclusivas para análise do modelo e este foi testado em conjunto com um relé SEL-787 de forma a permitir uma comparação dos resultados. Para a realização deste trabalho foram estudadas e analisadas as situações em que um relé de proteção diferencial de transformador enfrenta no campo, como energização de transformador, saturação, faltas externas, faltas externas com saturação de TC, faltas internas a seção diferencial e externa ao transformador e faltas internas ao transformador como falta espira-terra e entre espiras. Os mesmos testes foram aplicados ao modelo de relé diferencial já existente na biblioteca do RTDS com o intuito de verificar se realmente modelos genéricos apresentam resultados diferentes de modelos específicos. A contribuição da pesquisa foi o desenvolvimento pioneiro do modelo do relé de proteção diferencial no ambiente RTDS
Abstract: Due to the difficulties involving tests in real systems engineers continuously look for tools and models to simulate or emulate real systems inside laboratories. With this focus, this job had the objective of developing a transformer differential protection relay in Real Time Digital Simulator, RTDS, based on SEL-787 relay, manufactured by Schweitzer Engineering Laboratories Inc. The objective of creating a specific relay already in the market, and not a generic model relay, is due to the necessity of the laboratories studies give real results and also represent the real system. This actual representation gives the engineers a more concrete data to support future expansions of the national and international electric systems. After the development of the relay model itself, it was tested in conjunction with a real SEL-787 allowing comparison of the results. For the accomplishment of this job many different situations which interfere in the daily operation of the relay in the field such as inrush, saturation, external faults, external faults with current transformer saturation, internal fault to the differential section but external to the transformer and internal faults like turn-to-turn faults and ground faults were studied and analyzed. The same tests were applied to a differential relay model already in the RTDS library with the purpose to verify whether generic models have different results compared to specific models. This research formerly presents a transformer differential relay model of a commercial relay for RTDS library

Full textDet övergripande målet med examensarbetet är att porta Zephyr realtidsopera-tivsystem (OS) till LEON processorplattformen. LEON processorn är ursprungligendesignad för och förekommer ofta i datorsystem inom rymd p.g.a. sina feltolerantaegenskaper. LEON är kompatibel med den öppna SPARC v8 instruktionsuppsät-tningen vilken också tillåter utökning och anpassningar. Rapporten ger läsaren enöverblick av vilka steg som är nödvändiga för att skapa en fungerande arkitektur-port av ett OS. Vidare beskriver rapporten mer i detalj designen kring trådväxlingoch avbrottshantering, samt hur dessa anpassas för att utnyttja LEON specifikautökningar av SPARC till att nå högre prestanda. GR716 LEON3-FT introducerarpartitionering av SPARC registerfönster för att kunna minska tiden det tar opera-tivsystemet att växla trådar. Denna funktion har inte använts tidigare i något OS,och är därför av särskilt intresse att studera och karakterisera. Resultaten visar atttrådväxlingstiden minskat signifikant, samtidigt som determinismen blivit bättreoch därigenom är det nu enklare att designa system med hårda realtidskrav.

Systemet testat mot en annan AI som använder mer traditionella "Finite State Machines" in sin arkitekture. Testet utförs på tre olika banor som är olika stora. Systemet består utav en "Uppgiftshanterare" som har hand om alla aktiva och inaktiva uppgifter. En uppgift kan antingen vara utav låg-nivå, som används för att skicka kommandon till enheterna, eller utav hög-nivå för att göra mer avancerade strategier. Generalen planerar och skapar uppgifter som är mest fördelaktig för tillfället. För att skapa enheter som är effektiva mot fiendens enheter används ett prioritetssystem, där enhetens prioritet kalkyleras ut dynamiskt under spelets gång.

Full textInterprocessor communication is a vital part of any multiprocessor system. This work focuses on integration of an asynchronous message passing mechanism and a message notification support in the form of limited hardware queues. To fulfill requirements the interprocessor communication must be predictable, efficient, maintain memory integrity, and use the semantics of the available message passing mechanism. Various solution possibilities are identified, evaluated and compared, resulting in a design recommendation. The design uses memory restriction to build a firewall between the processors, using pointers to avoid message copying. The message queue is in the form of an array ring that can piggyback acknowledgement information. The design is general and applicable by a real-time operating systems using asynchronous message passing with explicit buffering, and has hardware support in the form of limited interrupt generating queues.

Esta dissertação apresenta uma aplicação do RTDS (Real Time Digital Simulator) na modelagem, simulação e análise comparativa a medições de um sistema fotovoltaico instalado. Descreve uma breve revisão das literaturas atuais no desenvolvimento de conversores para conexão à rede de distribuição de sistemas fotovoltaicos, e também comentários sobre as regulamentações envolvidas no Brasil e internacionalmente. O objetivo principal é comparar medições do sistema fotovoltaico real instalado no Centro de Excelência em Redes Elétricas Inteligentes (CERIn) da Universidade Federal de Itajubá (UNIFEI) com um modelo computacional desenvolvido na plataforma RTDS. Determinam-se os parâmetros dos equipamentos envolvidos no sistema elétrico real através da análise das folhas dados dos fabricantes, incluindo: os painéis fotovoltaicos com as respectivas associações, os dois inversores CC-CA, os dois transformadores da subestação, a carga elétrica do CERIn, e o alimentador da distribuidora CEMIG. O projeto e sintonia dos controladores também é detalhado e modelado no RTDS. Por fim são apresentados os resultados do modelo computacional projetado e simulado através de um script desenvolvido no RUNTIME do software RSCAD da plataforma de simulação em tempo real RTDS. Este script coleta amostras em dois vetores de dados meteorológicos gerados pelas medições reais de dois dias distintos, e executa variações de irradiância e temperatura no modelo, referente a dois cenários: um dia nublado e um dia de sol. Com isso, variáveis medidas na saída dos inversores modelados são comparadas às medições reais, o que demonstrou boa convergência dos dados com a realidade. Sugestões para trabalhos futuros também são apresentadas no final deste trabalho.

Full textElectronic systems are a growing need in modern societies, they can be found in a variety of forms, simple as an Alarm Clock at the bedside or very complex as a telecommunications satellite into orbit. Today, the majority of these inventions are based mainly on "systems on chips", in order to achieve their primary function: simplify our daily lives.However, because of their physical nature, these systems can suffer from malfunctions due to the environments in which they operate. Natural phenomena can cause hazards which may have serious consequences on system dependability.This thesis focuses on a specific class of systems on chip which are able to reconfigure dynamically and partially and their reliability. We explore the possibility of using their partial dynamic reconfiguration capability (PDR) for hardening applications on FPGAs. We have proposed the use of checkpoint approaches and context restoration for tolerance against transient faults. PDR is used for managing the context of hardware tasks present on the application. the use of RDP reduces changes to the original system and therefore the complexity of the resulting system. After identifying the limitations of the "Backward Error Recovery" approach into SRAM-based FPGAs platforms, we propose a new resource placement algorithm on FPGA to minimize the access time needed by check-pointing and rolling back operations of hardware tasks. The evaluation of the overall reliability of our approach is achieved through fault injection campaign on demonstration platform running on a Virtex-5 that integrates our reliability controller and hosts a data encryption application

Full textMultiprocessor Systems-on-Chip (MPSoC) offer superior performance while maintaining flexibility and reusability thanks to software oriented personalization. While most MPSoCs are today heterogeneous for better meeting the targeted application requirements, homogeneous MPSoCs may become in a near future a viable alternative bringing other benefits such as run-time load balancing, task migration and dynamic frequency scaling. This thesis relies on a homogeneous NoC-based MPSoC platform developed for exploring scalable and adaptive on-line continuous mapping techniques. Each processor of this system is compact and runs a tiny preemptive operating system that monitors various metrics and is entitled to take remapping decisions through code migration techniques and dynamic frequency scaling. This approach that endows the architecture with decisional capabilities permits refining application implementation at run-time according to various criteria

Full textEmbedded systems, more and more are gaining importance, due to the increase of features requested on equipments, the regulatory standards and the costumers and market requirements. This increment on requirements increases the software size and complexity, which importance significantly grows. Real-time operating systems represents a powerful tool to manage the complexity, help the software reuse and improve portability of the software and also reduce the time-to-market. This work aims to analyze the real-time operating systems, verifying their application on low cost embedded systems using small microcontrollers (8 and 16-bit), evaluating their characteristics and propose the best architectures for software development. To attend this proposal, it was performed a survey of Brazilian embedded system development, evaluates the low cost embedded system characteristics, discusses the viability of RTOS usage and performs a comparative study of embedded software architectures. Results show that simplified architectures like the Superloop presents vantages over the operating systems due to their low memory and processing consumption. The operating system, besides helping on time management and code modularity, is difficult to implement in small microcontrollers, due to the high memory and processing consumption. The operating systems are more applicable to small embedded systems with at minimum 4 Kbytes of RAM memory and process with maximum execution time (deadlines) over 1 ms, conditions that do not causes microcontroller overload. In this work is also presented an overview of Brazilian embedded system development.
