Abstract
A processing system includes clock circuitry that statically multiplies/divides a stimulus signal which can then be removed while a resultant product clock is still generated, A cascaded--dual tap delay line is employed having a single phase inversion which is looped back and logically ORed with the first edge of the stimulus signal to induce oscillation. A multiplier/divisor control signal adjusts the 'N' times multiplication by disabling the loop after the desired number of pulses is achieved within the period of the stimulus signal. 1/M multiplication is achieved by disabling the loop from oscillating for M stimulus clocks. Multiple frequencies can be dynamically realized on-the-fly without resynchronization by combining delayed clock pulses with a multiplexer.
