In one embodiment, a processor includes a minimum energy point (MEP) controller to: generate a change in thermal tracking information, based at least in part on prior and current thermal information; generate a change in activity tracking information, based at least in part on prior activity information and current activity information; and determine a MEP performance state based at least in part on the change in thermal tracking information and the change in activity tracking information. Other embodiments are described and claimed.

System, apparatus and method for sensor-driven and heuristic-based minimum energy point tracking in a processor

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.
