A method for graphics processor clock scaling comprises the following steps. A percentage of idle-time is calculated, based upon an elapsed idle-time and an elapsed active time. A graphics processor clock rate is reduced if the percentage of idle time is higher than a high limit threshold. The graphics processor clock rate is increased if the percentage of idle time is lower than a low limit threshold.

Graphics processor clock scaling based on idle time

A clock frequency controller for a processor and a method of operation thereof. The clock frequency controller may be embodied in a processor, including: (1) a processing core operable at a clock frequency to undertake a processing of a graphics application, and (2) a clock frequency controller coupled to the processing core and operable to adjust the clock frequency based on a current frame rate of the processing and a target frame rate for the processing.
