Abstract :
Today area-efficiency is an important factor in designing embedded systems. This paper presents a design space exploration based on an embedded VLIW processor for finding out the optimum architecture for ever increasing demands of embedded packet-processing applications. In our exploration, we use the VEX toolchain for exploring the effects of memory hierarchy, different architectural configurations, and compiler optimizations on both performance and area. Exploration results will find out the best architecture and compiler optimizations for VLIW embedded packet-processing engines to have area-efficiency as well as time-efficiency.
