Abstract
A semiconductor integrated circuit includes: a plurality of domains each supplied power supply voltage from corresponding one of a plurality of power supply units; and a plurality of operation control units each connected to corresponding one of the plurality of domains and controlling an operational state of the corresponding domain, wherein each of the domain transmits a operation change request to the corresponding operation control unit, the operation change request representing a request for a change of the operational state with a change in current value of the domain, and the operation control unit calculates a current change rate of the domain resulted from the change of operational state upon receiving the operation change request, and transmits a response signal approving the change of operational state to the corresponding domain in case of the current change rate is within a specified value.
