By exploiting parallel processing, the proposed scheduling scheme enhances energy saving capability of multicore processors forreal-time tasks while satisfying deadline and fault tolerance constraints. The scheme searches for a near minimum-energy schedule withina polynomial time, because finding the minimum-energy schedule on multicore processors is a NP-hard problem. The scheme consumesmanifestly less energy than the state-of-the-arts method even with low parallel processing speedup as well as with high parallelprocessing speedup, and saves the energy consumption up to 86%.
