ABSTRACT:
Power management methods for integrated circuits are disclosed. A system core block is disposed in a chip and comprises a central processing unit. A power control block is disposed in the chip and comprises a power management mechanism coupled to a power supply to control the supply of power to the system core block. The power management mechanism outputs a power down signal and stops supply of power to the system core block according to a power saving mode setting signal from the central processor unit and starts the supply of power to the system core block according to a power saving mode release signal.
