ABSTRACT:
A method and apparatus (10) for changing processor clock rate are provided in which control signals operate to change the rate of a clock signal output by clock switching logic (26). A processor (24) floats a system bus after the clock signal is changed. After the processor (24) has locked onto the new clock rate it is permitted to resume activity on the system bus.
