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.

Description

[0001] related application [0002] This application claims priority to US Provisional Patent Application No. 61 / 863,554, filed August 8, 2013, entitled "Intelligent Multicore Control For Optimal Performance Per Watt," which is hereby incorporated by reference in its entirety. Background technique [0003] Currently, manufacturers manage power consumption and thermal issues in multicore devices by throttling the processing clock frequency of the multiprocessor cores. Throttling the processing clock frequency of the multi-processor cores of a multi-core device can help manage power consumption and thermal issues by reducing the rate at which work is done by the multi-core processor. However, this technique focuses on managing these issues at the cost of performance. [0004] Mobile devices are increasingly incorporating multi-core processors to handle the demands of system and application software running concurrently on the mobile device. Mobile devices are limited in reachi...
