摘要
The present invention relates to a stochastic minimum-power scheduling method considering leakage power consumption when a multi-core processor performs periodic real-time tasks having variable computation. The stochastic minimum-power scheduling method considering the leakage power consumption of a multi-core processor for periodic real-time tasks having variable computation includes determining cores to be used for performing M periodic real-time tasks among all cores of the multi-core processor; turning off remaining cores other than the cores determined; allocating the M periodic real-time tasks to the determined cores; and determining an execution speed minimizing the stochastic expectation value of power consumption when each of the cores performs each of the M periodic real-time tasks. According to the present invention, by considering leakage power consumption when performing the real-time tasks having variable, uncertain computation on the multi-core processor, there is an effect in that it is possible to provide a scheduling method that may minimize power consumption based on a stochastic model.
