Abstract

An integrated circuit includes functional blocks, a power control unit controlling the provision of power to the different functional blocks of the integrated circuit, a detecting unit detecting if a turned off functional block is to be turned on, and a clock signal control unit controlling the provision of the clock signal for the functional blocks. The clock signal control unit interrupts the clock signal for the activated functional blocks of the integrated circuit for a predetermined number of clock cycles. The power control unit provides power to the turned off functional block during the interrupted clock cycles.
