AB - This paper proposes a scheduling scheme that enhances power consumption efficiency of periodicreal-time tasks using DVFS and power-shut-down mechanisms while meeting their deadlines on multicoreprocessors. The proposed scheme is suitable for dependent multicore processors in which processingcores have an identical speed at an instant, and resolves the load unbalance of processing cores by exploiting parallel processing because the load unbalance causes inefficient power consumption in previousmethods. Also the scheme activates a part of processing cores and turns off the power of unused cores.
The number of activated processing cores is determined through mathematical analysis. Evaluationexperiments show that the proposed scheme saves up to 77% power consumption of the previous method.
