Abstract
In one embodiment, the present invention includes an apparatus having an estimation logic to estimate a dynamic capacitance of a processor circuit of a processor during a plurality of processor cycles, a power gate calculator to calculate a control value for a power gate circuit coupled to a load line and between a voltage regulator and the processor circuit based on the dynamic capacitance estimate, and a controller to control an impedance of the power gate circuit based on the control value. Other embodiments are described and claimed.
