Abstract:
In a computing device it may be determined whether to power down a subsystem based on how long the subsystem has been idle and based on one or more measurements of subsystem current consumption, subsystem bandwidth usage, and subsystem efficiency. An idle power-down count value may be determined based on the measurements, using predetermined relations among subsystem current consumption, subsystem bandwidth usage, and subsystem efficiency. The subsystem may be powered down based on a determination of whether the subsystem has been idle for an interval not less than the idle power-down count value.
