A method for adapting power consumption of a processor based upon an
application demand is provided. The method initiates with determining an
application demand based upon a current processing operation. Then, a
time interval associated with the application demand is determined. Next,
unnecessary power consuming functions for the application demand are
determined. Then, a clock frequency for the unnecessary power consuming
functions is reduced for the time interval. In one embodiment, the power
is terminated to the unnecessary power consuming functions. In another
embodiment, the clock frequency of the processor is adjusted for at least
a portion of the time interval. A program interface for adapting power
consumption of a computer system, processor instructions for adapting
power consumption of a computer system and a processor are included.
