ABSTRACT:
An apparatus, a method, and a computer program are provided to disable clock distribution. In microprocessors, the clock distribution system can account for a substantial amount of power consumption. Disabling the clock distribution system, however, has been difficult because of the usual requirement for a separate clock for control logic. Therefore, combinational logic can be employed to disrupt the clock distribution and allow a processor to be awakened without a need for a separate clock.
