Metodologia de Co-projecto Hardware/Software para arquitecturas computacionais reconfiguraveis utilizando uma participacao baseada no paralelismo implicito

The latest development of the electronic system production technology leads to new design approaches. The design methodology called hardware/software co-design means meeting system-level objectives by exploiting the synergism of hardware and software through their concurrent design. The design methodology developed in this work is directed to reconfigurable systems used for custom computing or rapid proto typing. The developed design methodology and the tools based on it offer a solution for three main problems in the area of hardware/software co-design: system modelling, hardware/software partitioning and the implementation of the resulting parts. For the initial system specification was used the high level programming language C, and, the system is modelled using control data flow graph. The hardware/software partitioning is accomplished in two steps: parallelization of the initial specification and final partitioning. The final partitioning splits the system into two concurrently executed parts. The final system implementation is achieved by synthesis of the hardware configuration and generation of the software. At the end of the dissertation some examples are presented demonstrating the potential of the developed design methodologyAvailable from Fundacao para a Ciencia e a Tecnologia, Servico de Informacao e Documentacao, Av.
