Abstract
A processor (400) includes a clock source (402), a central processing unit (CPU) (408), and a clock generator (404). The clock source (402) includes an output for providing a periodic clock signal. The CPU (408) includes an input for receiving a CPU clock signal. The clock generator (404) includes a first input coupled to the output of the clock source (402), a second input for receiving a mode signal that indicates an output frequency, and an output coupled to the input of the CPU (408). The clock generator (404) provides the CPU clock signal using periodic pulse skipping such that the CPU clock signal has a number of transitions over a unit of time corresponding to the output frequency.
