Future multiprocessor chips will integrate many different units, each tailored to a specific computation. When designing such a system, a chip architect must decide how to distribute the available limited system resources, such as area, power and energy among all the computational units. We introduce MultiAmdahl, an analytical optimization technique for resource sharing among heterogeneous units. We identify the optimal resource allocation in the unit using the performance of each computational unit, the workload, the target design goal, and the total available resource. We conclude by analyzing the impact of our optimization framework on chip design.
