Heterogeneous multiprocessor on chip compiler, architecture, place and route design space exploration

Multiprocessors system on chip are strongly emerging as best candidates for complex embedded applications. Heterogeneous multiprocessors bring an added value by allowing customization of processors to match required constraints in terms or area, performance and energy consumption. This customization of processors opens up a larger design space than homogeneous multiprocessors and naturally attracts the use of additional customization at various levels. In this paper we describe the design space exploration benefits of heterogeneous multiprocessors of the combined effects of compiler, architecture and place and route. A case study of a 5 way heterogeneous multiprocessor validates our approach.
