Abstract

See full text

The data processing system has: a plurality of hardware resources each having at least one standby mode; a control part for controlling execution of a task achieved by using, of the plurality of hardware resources, predetermined ones, and a working status of each hardware resource; and a power-source part for controlling supply of a power source to each hardware resource. The control part performs the scheduling of a scheduled execution time of the task based on information for determining a timing of executing the task, and calculates a standby time of the hardware resource based on a result of the scheduling. The control part compares the standby time with a break-even time depending on the standby mode, thereby deciding whether or not to cause each hardware resource to transition to the standby mode.
