Abstract:
In order to save a sub-threshold leak current during operation of processor, a decision circuit (instruction decoder) inputs an instruction signal and outputs an operation mode signal regarding the level of a leak current based on information about use of the circuit block. Thereby, a sub-threshold leak current in the circuit block not used can be saved.
