Semiconductor integrated circuit, semiconductor integrated circuit control method, and terminal system

Abstract

A semiconductor integrated circuit judges whether a power unit is performing a discharge operation or a charge operation. To reduce clock skew between a plurality of logic blocks in the semiconductor integrated circuit, when the power unit is performing the charge operation, the semiconductor integrated circuit determines a logic block that needs to be operated for the execution of a target process, as an operation block whose operation is to be started, and, determines, in the rest of the logic blocks, a logic block having a termination rate whose value is larger than a value of the minimum termination rate, as the operation block whose operation is to be started, the value of the termination rate being larger by more than a predetermined value.
