In one embodiment, a processor includes: at least one core to execute a workload; a voltage regulator to provide an operating voltage to the at least one core; and a power controller coupled to the voltage regulator. The power controller may control the voltage regulator to provide the operating voltage, and may have a voltage regulator control circuit to select one of a plurality of power state profiles based at least in part on a classification of the workload, and to cause an update to a power state of the voltage regulator according to the selected power state profile. Other embodiments are described and claimed.

In one embodiment, a method receives data regarding processing of a workload by a processor. The data is input into a prediction engine configured to classify the data into a plurality of workload classifications. Each workload classification describes different temporal behavior of the workload. Then, the method outputs a prediction for at least one of the plurality of workload classifications, wherein the prediction is used to control performance of the processor in an upcoming period of time.
