Abstract:
A power supply device includes: a first supply section that supplies power in accordance with an extent of a load in processing in a processing device by applying a voltage to the processing device which processes data; and a second supply section that supplies, to the processing device, power smaller than the supplying power by the first supply section, in accordance with an extent of a load in processing in the processing device to increase and decrease a voltage with respect to the application voltage by the first supply section.
