Abstract
Providing deterministic frequency and voltage enhancements for a processor is disclosed. In an embodiment, a microcontroller on a processor identifies a plurality of parameters related to a processor, the plurality of parameters including at least a current supplied to the processor; determines, in dependence upon the plurality of parameters, one or more frequency scaling indexes including determining an effective switching capacitance ratio; identifies, in dependence upon the one or more frequency scaling indexes, a predetermined frequency parameter for the processor; and transitions, based on the frequency parameter, the processor to a target clock frequency. In another embodiment, a microcontroller on a processor decreases, incrementally, a power supply voltage for a processor; determines that a voltage droop parameter exceeds a voltage droop parameter threshold; and increases, incrementally, the power supply voltage in response to determining that the voltage droop parameter exceeds a voltage droop parameter threshold.
