METHOD FOR MANAGING POWER FOR MULTI-CORE PROCESSOR, RECORDED MEDIUM FOR PERFORMING METHOD FOR MANAGING POWER FOR MULTI-CORE PROCESSOR AND MULTI-CORE PROCESSOR SYSTEM FOR PERFORMING THE SAME

摘要

PURPOSE: A power management method of multi-core processor, a recording medium recording power management method of the multi-core processor, and multi-core processor system executing the same are provided to satisfy service quality related to execution of an application program by allocating optimal clock frequency by considering deadline of processors allocated to each core. CONSTITUTION: A parallel processing interval is determined based on whether information directing start or completion of a parallel processing interval exists or not(220). Whether the determined parallel processing interval is an interval that firstly executed interval or not(230). If the determined parallel processing is the firstly executed interval, information for distinguishing a currently executed program code in the determined parallel processing interval is stored(240). An occupancy rate of an idle section is measured in the determined parallel processing interval(250).
