Resumo: 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 strategy implies in high hardware redesign costs, breaks binary compatibility and results in a high overhead in the software development process.
Therefore, focusing on area savings, low energy consumption, binary compatibility maintenance and mainly software productivity improvement, we propose the exploitation of Custom Reconfigurable Arrays for Multiprocessor System (CReAMS). CReAMS is composed of multiple adaptive reconfigurable systems to efficiently exploit Instruction and Thread Level Parallelism (ILP and TLP) at hardware level, in a totally transparent fashion. Preliminary results show a reduction of 37% in energy-delay product (EDP) on average, compared to an ordinary multiprocessing platform when assuming the same chip area.

Palavras-chave: Multiprocessors, Reconfigurable Architectures, Instruction and thread level parallelism.
