In this paper we extend and analyse Amdahl’s and Hill-Marty laws to general heterogeneous on-chip cluster era, without the abstract limitation of base core equivalents (BCEs). To understand the relative merits between speedup and the cluster characteristics, including microprocessors amount, accelerators speedup, and task partitioning plans, we also analyse the theoretical results about how the extended Amdahl’s Law is applied to leverage load balancing of a heterogeneous on-chip cluster. Simulation results demonstrate that our extended model reinforces state-of-the-art performance evaluation methods for hybrid MPSoC architectures and also provide creditable new insights to heterogeneous research communities, in particular for scalable FPGA based on-chip cluster domains. |
