ABSTRACT:
One embodiment of the invention comprises, in each clock zone of a central processing unit, at least one sensor that generates a power signal indicative of a power supply voltage within the clock zone, a clock generator for providing a variable frequency clock to the clock zone, and a controller for controlling an operating frequency of the clock generator in response to the power signal and in response to frequency adjustment communications from other clock zones.
