<p><P>PROBLEM TO BE SOLVED: To provide a task processing system and a task processing method for reducing power consumption, and preventing overhead or processing load from increasing, in a system of frequently switching a frequency. <P>SOLUTION: A main processor 1 determines at least one of tasks to be executed by a sub processor 2 in each of a plurality of time segment each having a predetermined length and determines, by the end of an nth (n is an integer that satisfies n≥1) time segment, a clock frequency necessary for executing the task within an (n+1)th time segment based on information of a required number of cycles for the task to be executed by the sub processor 2 in the (n+1)th time segment. The clock generation/control circuit 7 supplies, in the (n+1)th time segment, to the sub processor 2 a clock signal 16 according to the clock frequency determined by the main processor 1 in the nth time segment. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
