Abstract
A semiconductor integrated circuit provided with a processing unit that repeats a processing state and a standby state, comprises an obtaining unit configured to obtain a period of the standby state as a standby period; and a control unit configured to hold a plurality of candidate voltages in association with pieces of recovery information corresponding to recovery times required for the processing unit to return to a normal operation voltage from the candidate voltages in the standby state, and to control a standby voltage of the processing unit in the standby state in accordance with the candidate voltage associated with the piece of recovery information corresponding to a recovery time that is shorter than the standby period among the plurality of candidate voltages.
