Abstract
An apparatus and method for dynamically controlling the maximum frequency of operation of the IC is provided. The invention optimizes power consumption in a device by measuring a current maximum frequency of operation and adjusting IC operating voltage to provide a desired maximum operating frequency. The invention provides an apparatus and method for controlling multiple voltages in an IC to independently adjust maximum operating frequencies for a plurality of separate portions of the IC. The invention may equally be applied to a group of ICs. The invention further provides a method for calibrating an IC. Thus, the apparatus facilitates the operation of an IC at a minimum voltage for a selected maximum frequency, thereby minimizing power consumption overall a wide range of operating frequencies.
