Abstract :
To reach current SoCs constraint of flexibility without loosing performance, system designers need to avoid custom logic and replace it by multiple processors and custom instruction extensions. In this paper, we bring a new codesign methodology which targets MPSoC comprising of multiple configurable processors. By applying this methodology to an MPEG-4 encoder we show that the approach gives a speedup factor that is almost linear with the number of processors.
