摘要： Systems and methods of power management provide for controlling the idleness of a processor based on an operating system schedule. The idleness of at least one device is synchronized with the idleness of the processor. Idleness synchronization may involve deferring bus transactions, suspending memory refresh, turning off power to clock sources and turning off power to combinatorial logic during an idle window in the OS schedule.
