Abstract
Adaptive voltage control. In accordance with a first embodiment of the present invention, a desirable operating frequency for the microprocessor is determined. Information stored within and specific to the microprocessor is accessed. The information can comprise coefficients of a quadratic approximation of a frequency-voltage characteristic of the microprocessor. An efficient voltage for operating the microprocessor at said desirable operating frequency is computed. The microprocessor is operated at the efficient voltage.
