Two-Dimensional Matrix Partitioning for Parallel Computing on Heterogeneous Processors Based on Their Functional Performance Mod
Abstract. The functional performance model (FPM) of heterogeneous processors has proven to be more realistic than the traditional models because it integrates many important featur...

FSMD Functional Partitioning for Low Power
Previous work has shown that sizable power reductions can be achieved by shutting down a system's sub-circuits when they are not needed. However, these shutdown techniques fo...
