METHOD FOR PERFORMING ADAPTIVE VOLTAGE SCALING (AVS) AND INTEGRATED CIRCUIT CONFIGURED TO PERFORM AVS

摘要

An integrated circuit (IC) includes an adaptive voltage scaling (AVS) controller configured to control a voltage supplied to a portion of the IC and at least one sensor configured to sense at least one state of the IC and to provide an output signal indicative of the at least one sensed state to the AVS controller, the IC having a first setting and a second setting, the AVS controller being configured to use the output signal to control the voltage in the first setting and the AVS controller being configured to control the voltage independently of the output signal in the second setting. Also a method of performing AVS is provided.

1. A method of power management comprising:
providing an integrated circuit (IC) having an adaptive voltage scaling (AVS) controller; performing a first AVS operation on a voltage supplied to a portion of the IC using the AVS controller under a first condition; and not performing the first AVS operation on the voltage supplied to the portion of the IC under a second condition.
