ABSTRACT:
A component of a computing device such as a processor is operated based on a clock signal oscillating at a frequency. Power management for the computing device is performed by adjusting the frequency of the clock signal applied to the component when warranted and also by idling the component when the component experiences a period of inactivity longer than an idle detection metric scaled according to the adjusted frequency.
