Claim:
An electronic apparatus comprising: a processor acting as a master device, said processor being operable to process a plurality of threads; a plurality of devices, each of which acts as a slave device; and a peak power-managing unit operable to manage peak power, wherein said processor addresses, to said peak power-managing unit, a device use request for use of a target device among said plurality of devices when said processor processes the plurality of threads, wherein said peak power-managing unit in receipt of the device use request issues, to said processor, a device use permit notification that permits the device use request, when determining that a total power consumption value is equal to or smaller than a predetermined value, the total power consumption value including power consumption value added by operation of the target device, and suspends the device use request when determining that the total power consumption value is greater than the predetermined value, wherein the device use request is suspended until the total power consumption value is again equal to or smaller than the predetermined value; wherein said processor receives the device use permit notification of the target device from said peak power-managing unit, and then sets up a course of action of the target device in accordance with most currently updated information.
