ABSTRACT:
A system on a chip includes a processing module, ROM, RAM, and a clocking circuit. The clock circuit is coupled to produce a first clock signal when the SOC is in a low power mode and to produce a second clock signal when the SOC is in a performance mode, where the first clock signal is less accurate than the second clock signal. The clock circuit consumes more power when producing the second clock signal than when producing the first clock signal.
