A simulation-based power-aware architecture exploration of a multiprocessor system-on-chip design

We present the design exploration of a system-on-chip architecture dedicated to the implementation of the HIPERLAN/2 communication protocol. The task was accomplished by means of an ad-hoc C++ simulation environment, integrating power models for CPUs, memories and buses used in the design and incorporating software profiling capabilities. The architecture is based on two ARM microprocessors, an AMBA bus and a local bus, DMA unit and other peripherals. Software mapping on the processor has been based on the power/performance profiling results.
