METHOD AND APPARATUS FOR TRANSITIONING DEVICES BETWEEN POWER STATES BASED ON ACTIVITY REQUEST FREQUENCY

摘要

A method for transitioning power states in a device (210, 300) includes designating a first reduced power state as a target power state. A first expected residency for the target power state is determined based on a counting of activity requests (230) associated with the device (210, 300). The device (210, 300) is transitioned to the target power state responsive to the expected residency satisfying a first predetermined threshold.
