ABSTRACT:
Within a microprocessor, multiple synchronous clock signals of arbitrary integer and non-integer ratios are produced with conventional digital divider circuitry. The various integer and non-integer clock signals can be provided to processor circuitry, bus circuitry, and coupled memory circuitry. Non-integer ratio clock signals can be produced out-of-phase with the system clock signal.
