Abstract:
A method including receiving an indication of a number of active processing units in a computer processor; in response to receiving the indication, determining an appropriate operating voltage margin for the computer processor; reducing an operating frequency of the active processing units in response to receiving the indication; adjusting a power supply to increase or decrease a voltage to the computer processor in accordance with the appropriate operating voltage margin; and increasing the operating frequency of the active processing units in response to an acknowledgment that the power supply has been adjusted.
