Current control for a multicore processor

One or more non-transitory computer-readable media (NTCRM) having instructions, stored thereon, that when executed by circuitry of a multicore processor cause the circuitry to:

• receive one or more current utilization measurements for respective ones of a plurality of cores of the multicore processor, the one or more current utilization measurements include one or more current utilization measurements for a first core of the plurality of cores;
• determine to throttle the first core based on the one or more current utilization measurements for the first core exceeding a threshold and to release throttling of the first core based on the one or more current utilization measurements for the first core returning to within the threshold;
• and
• determine whether to change an allocation of a power budget for the first core based on a frequency of the throttling and releasing of the throttling of the first core.

A computing system comprising:

• a motherboard;
• a multicore processor coupled to the motherboard, the multicore processor including:
• a plurality of processor cores;
• a plurality of current sensors to provide indications of whether one or more current utilization measurements of respective ones of the plurality of processor cores exceeds a threshold;
• and
• control circuitry to:
• determine to throttle a first processor core of the plurality of processor cores based on the indications;
• and
• send a throttle request to the first processor core based on the determination, the first processor core to throttle according to a default throttling parameter if the throttle request does not indicate a throttling parameter.
