MULTI-CORE PROCESSOR FREQUENCY LIMIT DETERMINATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17969524 titled 'MULTI-CORE PROCESSOR FREQUENCY LIMIT DETERMINATION

Simplified Explanation

Embodiments herein relate to a technique to be performed by a power control unit (PCU) of an electronic device. Specifically, the PCU may identify, based on a metric related to an activity level of a processor core of a multi-core processor of the electronic device, first, second, and third weights that are respectively related to first, second, and third cores of the multi-core processor. Based on these weights, the PCU may identify a number of active processor cores of the multi-core processor, and alter a frequency limit of the multi-core processor accordingly. Other embodiments may be described and claimed.

• The patent application describes a method for power control in an electronic device with a multi-core processor.
• The technique involves identifying the activity level of each processor core and adjusting the frequency limit of the processor based on this information.
