Abstract
Dynamic frequency and voltage scaling for a computer processor, including retrieving information specifying a nominal operating point of frequency and voltage and an operating range of frequency and voltage for the processor; creating, by the power management module dynamically at run time in dependence upon the retrieved information, a table of frequency, voltage pairs, each pair specifying an operating point of frequency and voltage for the processor, each pair disposed upon a line drawn in frequency-voltage space through the nominal operating point between the minimum operating point and the maximum operating point, the distance between each pair defined in dependence upon a minimum change in power supply voltage supported by the power supply; and selecting and applying, by the power management module from the table, an operating voltage and frequency for the processor in dependence upon current operating conditions of the processor.
