1. A transparent and energy aware reconfigurable multiprocessor platform for efficient ILP and TLP exploitation
As the number of embedded applications is increasing, the current strategy of several companies is to launch a new platform within short periods, to execute the application set more efficiently, with low energy consumption. However, for each new platform deployment, new tool chains must come along, with additional libraries, debuggers and compilers. This str

2. New techniques for improving the performance of the lockstep architecture for SEEs mitigation in FPGA embedded processors
The growing availability of embedded processors inside FPGAs provides unprecedented flexibility for system designers. The use of such devices for space or mission critical applications, however, is being delayed by the lack of effective low cost techniques to mitigate radiation induced errors. In this paper a non invasive approach for the implementation of f

3. Dynamic load-balancing : a new strategy for weather forecast models
Weather forecasting models are computationally intensive applications and traditionally they are executed in parallel machines. However, some issues prevent these models from fully exploiting the available computing power. One of such issues is load imbalance, i.e., the uneven distribution of load across the processors of the parallel machine. Since weather

4. Arquitetura modular de processador multicore, flexível, segura e tolerante a falhas, para sistemas embarcados ciberfísicos. / Modular multicore processor architecture, flexible, securi and fault tolerant, to embedded cyber-physical systems.
Cyber-physical Systems (CPS) are systems where there is an union between computing and physics. The CPS will be used in several areas, forming a new era of systems or devices and could be anywhere, being used by anyone and anything. Applications for CPS include highly reliable medical systems and devices, traffic control and security, advanced automotive, pr

5. SPARC16 : uma nova visão de compressão para processadores SPARC / SPARC16 : a new compression approach for SPARC processors
Processadores RISC podem ser usados para atender a crescente demanda por desempenho requerida por sistemas embarcados. Entretanto, essas arquiteturas têm como desvantagem uma densidade de código ruim. Recodificações do conjunto de instruções, como o MIPS16 e o Thumb, representam uma abordagem eficiente para lidar com esse problema. Esse trabalho propõ

6. DevC: uma linguagem de suporte ao desenvolvimento concorrente de device drives e modelos de controladores de entrada e saÃda
Modern electronic products incorporate several features, combining mobility, computational power, a great capacity for communication and facility for interfacing. Nevertheless, integrating such functionalities increases the complexity of the design. The design of such products includes an embedded system that implements their functionalities in a combined so

8. Controlador adaptativo backstepping a estrutura variável
In this work, a Variable Structure Adaptive Backstepping Controller (VS-ABC) for monovariable, linear time invariant plants with relative degree one is presented. Instead of traditional integral adaptive laws for estimating the plant parameters, switching laws are used to increase robustness to parametric uncertainties and disturbances, as well as, to improv

10. A power estimation design for the Altera Nios II processor / Projeto de um estimador de potência para o processador Nios II da Altera
Nowadays, optimization of hardware and software systems does not necessarily mean increasing their computational performance. Due to the popularization of battery-operated embedded systems, energy comsumption has become a very critical issue. Several tools have been created to model, optimize, and estimate energy consumption, allowing power constraints to be

11. Suporte a simulação distribuída em SystemC
The ever increasing evolution of microelectronics allows the integration of more and more complex systems in semiconductor devices. Present day System on Chip (SoC) may integrate processors, memories, analog, mixed-signals, digital and RF modules in a single chip. The simulation of a SoC is a fundamental step in system design, since it permits the verificati

12. A platform development framework and a debugging mechanism based on computacional reflection / Um framework de desenvolvimento de plataformas e um mecanismo de depuração baseado em reflexão computacional
Digital systems are becoming more and more complex through the years, putting general purpose processors together with specialized hardware and buses into the same silicon die, due to power, area and performance constraints. In order to deal with this complexity and a short time-to-market, designers are adopting high level hardware descriptions, based on lan
