Abstract：In order to solve the problem of high energy consumption caused by the high performance of multi-core processor,the task migration overhead problem in TL-DVFS algorithm was analyzed,and an energy saving scheduling algorithm ITL-DVFS based on TL plane was proposed.Without increasing the time complexity of the algorithm,the migration overhead of each TL plane at initial time can be effectively reduced through the operation on the heap.In combination with the global dynamic voltage frequency modulation technology,the voltage and frequency of multi-core processor at both initial time and the sporadic task release time on the TL plane algorithm were dynamically adjusted.The results show that ITL-DVFS can effectively reduce the task migration overhead,and can effectively decrease the power consumption of multi-core processor when the load reaches a certain value.
