Proactive voltage droop reduction and/or mitigation in a processor core

A computer-implemented method, comprising:

• applying, by a processor core, during a first stage of a processor pipeline, a voltage droop mitigation countermeasure prior to a predicted increase of a level of power to be consumed during a second stage of the processor pipeline, wherein the voltage droop mitigation countermeasure comprises:
• determining an overall noise level based on a combination of a local noise level and a remote noise level;
• and
• continuing, by the processor core, to generate a throttling signal based on a determination that a difference between an amount of noise mitigated and local detected voltage change information fails to be within a defined range;
• and
• stopping, by the processor core, generation of the throttling signal based on a determination that a difference between an amount of noise mitigated and the local detected voltage change information is within the defined range.

A computer program product that facilitates proactive voltage droop mitigation, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions are executable by a processor to cause the processor to:

• apply, during a first stage of a processor pipeline, a voltage droop mitigation countermeasure prior to a predicted increase of a level of power to be consumed during a second stage of the processor pipeline, wherein the voltage droop mitigation countermeasure comprises determination of an overall noise level based on a combination of a local noise level and a remote noise level;
• a continuation of generation of a throttling signal based on a determination that a difference between an amount of noise mitigated and local detected voltage change information fails to be within a defined range;
• and
• a stopping of generation of the throttling signal based on a determination that a difference between an amount of noise mitigated and the local detected voltage change information is within the defined range.
