Controlling a processing performance level depending on energy expenditure

Abstract:

Circuitry is provided to control a performance level of a processing device depending on two or more operating points of the processing device. An operating point has a corresponding frequency and a corresponding voltage. The performance-level control circuitry arranged to cross-multiply parameters corresponding to a first operating point and a second, different operating point of the processing device. A relative energy expenditure of the first operating point and the second operating point is determined based on the cross multiplication. An operating point of the processing device is selected depending on the determined relative energy expenditure. An apparatus having the performance level control circuitry, machine readable instructions for implementing the performance level control and a corresponding method are also provided.
