Abstract

The described embodiments include a computing device with one or more entities (processor cores, processors, etc.). In some embodiments, during operation, a thermal power management unit in the computing device uses a linear prediction to compute a predicted duration of a next idle period for an entity based on the duration of one or more previous idle periods for the entity. Based on the predicted duration of the next idle period, the thermal power management unit configures the entity to operate in a corresponding idle state.
