Abstract
An apparatus and method for temperature-constrained frequency control and scheduling. For example, one embodiment of a processor comprises: a plurality of cores; power management circuitry to control a frequency of each core of the plurality of cores based, at least in part, on a temperature associated with one or more cores of the plurality of cores, the power management circuitry comprising: a temperature limit-driven frequency controller to determine a first frequency limit value based on a temperature of a corresponding core reaching a first threshold; frequency prediction hardware logic to predict a temperature-constrained frequency of the corresponding core based on the first frequency limit value and an initial frequency limit value; and performance determination hardware logic to determine a new performance value for the corresponding core based on the temperature-constrained frequency, the new performance value to be provided to a task scheduler.
