Abstract: The various aspects provide for a device and methods for intelligent multicore control of a plurality of processor cores of a multicore integrated circuit. The aspects may identify and activate an optimal set of processor cores to achieve the lowest level power consumption for a given workload or the highest performance for a given power budget. The optimal set of processor cores may be the number of active processor cores or a designation of specific active processor cores. When a temperature reading of the processor cores is below a threshold, a set of processor cores may be selected to provide the lowest power consumption for the given workload. When the temperature reading of the processor cores is above the threshold, a set processor cores may be selected to provide the best performance for a given power budget.
