Abstract
A system and method for dynamically changing the clock frequency of a system clock is disclosed. The invention includes selecting a peripheral interface clock signal from a plurality of currently active peripheral interface clock signals, each operating at a particular frequency. The selected peripheral interface clock signal operates at the highest frequency of the plurality of currently active peripheral interfaces clock signals. Once selected, the frequency of the system clock is set equal to the frequency of the selected peripheral interface clock signal.
