Abstract: Techniques facilitating voltage droop reduction and/or mitigation in a processor core are provided. In one example, a system can comprise a memory that stores, and a processor that executes, computer executable components. The computer executable components can comprise an observation component that detects one or more events at a first stage of a processor pipeline. An event of the one or more events can be a defined event determined to increase a level of power consumed during a second stage of the processor pipeline. The computer executable components can also comprise an instruction component that applies a voltage droop mitigation countermeasure prior to the increase of the level of power consumed during the second stage of the processor pipeline and a feedback component that provides a notification to the instruction component that indicates a success or a failure of a result of the voltage droop mitigation countermeasure.
