Abstract:

We present an evaluation algorithm based on task division and scheduling at run-time on heterogeneous multi-core systems. The algorithm can achieve speedups of specific tasks running on different configurations for multi-core platform within the reconfigurable hardware architectures. We build a simulation environment and implement a prototype on FPGA. Experimental results show that the algorithm can achieve 90% of theoretical speedup with dependency of different tasks and 98.9% without data dependency.

Key words: multi-core platform, performance evaluation, task division and scheduling, reconfigurable computing
