Title
(EN) CONTROLLING POWER GATE CIRCUITRY BASED ON DYNAMIC CAPACITANCE OF A CIRCUIT
(FR) COMMANDE DE CIRCUITS DE GRILLE DE PUISSANCE BASÉE SUR LA CAPACITÉ DYNAMIQUE D'UN CIRCUIT
Abstract
(EN)
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.
