ABSTRACT:
A circuit for transitioning clocking speeds, or frequencies, is provided. With this circuit, a clocking circuit providing a first clock signal at a first clock frequency is coupled to a counter. A comparator and a first divider are coupled to an output of the counter. The first divider outputs a second clock signal at a second clock frequency. A second divider is interposed between the clocking circuit and the counter. A processor is coupled to an output of the first divider.
