Abstract
An information processing apparatus, which operates in a multi-task mode, calculates a total consumption power of devices used by each task, and assigns higher execution priority to a task which uses a device with the largest consumption power, thereby shortening the execution time of the device with the largest consumption power, and suppressing the total consumption power of the apparatus. When a device is started upon switching of tasks, if the total consumption power exceeds the allowable power of the apparatus by a power consumed upon restarting of the device, the task is set in a waiting state until operations of other devices are completed, the consumption power is lowered, and it is ready to use the device by the task.
