ABSTRACT:
A power supply device of the invention includes: a supply section that supplies power to a second processing device which processes data in response to processing execution by a first processing device which processes data; a load detection section that detects a load of processing execution by the first processing device; and a power control section that causes the supply section to increase or decrease power supply according to the magnitude of load detected by the load detection section. The load of processing execution by the first processing device disposed in the upstream side relative to the second processing device is detected, and power supply to the second processing device is increased or decreased according to the detected magnitude of load. Accordingly, even when the amount of processing data sharply increases, sufficient power can be unfailingly supplied to the second processing device.
