Abstract
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.
