ABSTRACT:
A semiconductor integrated circuit includes: an internal circuit; a detecting circuit which detects an element characteristic of the internal circuit; a calculating circuit which calculates a first consumption energy consumed when a power gating operation is performed on a task processed by the internal circuit and a second consumption energy consumed when an operation of reducing a voltage and a frequency is performed in accordance with the element characteristic; and a switching circuit which performs the power gating operation on the internal circuit when the first consumption energy is smaller than the second consumption energy and performs the operation of reducing a voltage and a frequency when the second consumption energy is smaller than the first consumption energy.
