Abstract

A method for dynamically varying a clock frequency in a processor. The method of one embodiment comprises driving a clock distribution network with a clock output from a phased locked loop (PLL). An adjustable clock generator is locked with the phased locked loop. The adjustable clock generator is substituted for the PLL on the clock distribution network.
