Abstract
A processor includes an execution engine and a power controller. The execution engine includes circuitry to determine an increased current for the execution engine. The power controller includes circuitry to determine a new dynamic capacitance for the execution engine based upon the increased current, calculate a new power consumption for the execution engine based upon the new dynamic capacitance, utilize the new power consumption to evaluate a new aggregate demand for power of a plurality of engines including the execution engine, and evaluate power provisioning of the processor based upon the new power consumption for the execution engine.
