Abstract

Changes in a clock signal, such as phase changes or resets, may propagate glitches, such as shortened clock cycles that may cause undesired effects in subsequent circuitry, to circuitry reliant upon the clock signal. Glitches in the clock signal may not allow a circuit component to finish operating before the shortened next clock cycle arrives, which may cause an unknown or error state in the circuit component. As such, clock change circuitry may reduce or eliminate glitches by holding the clock signal in a particular state (e.g., logically low) while the change occurs, and release the clock signal afterwards, effectively skipping or overall reducing potentially glitched clock cycles.
