Abstract
Systems and methods of managing power consumption provide for placing a processor in a non-snoopable state while a storage interface associated with the processor is enabled for bus mastering. In one embodiment, the bus mastering results in traffic between the storage interface and a storage device, where the traffic is monitored and the processor is placed a snoopable state when traffic is moving, and in the non-snoopable idle state if the traffic ceases for a period of time.
