Abstract
A sleep mode in which power consumption is reduced to a prescribed value or smaller is achieved, while convenience for a user is maintained by shortening the time taken to recover from the sleep mode. The temperature of an LSI is measured or estimated when shifting to the sleep mode, and an apparatus enters a power supply shutoff sleep mode using power supply separation or a clock-gating sleep mode in accordance with the measured or estimated value of the temperature. In the case where power supply shutoff is selected, after entering the sleep mode, power supply is resumed and then the apparatus enters the clock-gating sleep mode in accordance with the measured temperature or the estimated temperature of the LSI.
