Power governance of processing unit

One or more non-transitory computer-readable media comprising instructions that, upon execution of the instructions by logic that is part of or communicatively coupled with a processing unit (PU), are to cause the logic to:

• measure a current utilization of a processing unit (PU) at a current operating frequency;
• determine, based on the measured current utilization, a change in utilization or power of the PU;
• determine, based on the identified change in utilization or power, a new target quantified power expenditure to be applied in a subsequent processing cycle of the PU;
• and
• identify, based on the new target quantified power expenditure, a new operating frequency for the PU;
• and
• update a current operating frequency of the PU to the new operating frequency.

A processing platform comprising:

• a processing unit (PU);
• and
• power governance circuitry communicatively coupled with the PU, wherein the power governance circuitry comprises:
• measurement circuitry to:
• measure a current utilization of a processing unit (PU) at a current operating frequency;
• and
• determine, based on the measured current utilization, a change in utilization or power of the PU;
• and
• frequency control circuitry to:
• determine, based on the identified change in utilization or power, a new target quantified power expenditure to be applied in a subsequent processing cycle of the PU;
• and
• identify, based on the new target quantified power expenditure, a new operating frequency for the PU;
• and
• update a current operating frequency of the PU to the new operating frequency.
