As the number of transistors on a chip continues increasing the power consumption has become the most important constraint in processors design. Therefore, to increase performance, computer architects have decided to use multiprocessors. Moreover, recent studies have shown that heterogeneous chip multiprocessors have greater potential than homogeneous ones. We have built a modular simulator for heterogeneous multiprocessors that can be configure to model IBM's Cell Processor. The simulator has been validated against the real machine to be used as a research tool.
