MULTIMODE,UNIFORM-LATENCY CLOCK GENERATION CIRCUIT

A multimode, uniform-latency clock generation circuit (CGC) is described herein. In one example, the multimode, uniform-latency CGC generates a pulse clock signal via a clock generation path responsive to a clock chopping signal being active and generates a phase clock signal via the same clock generation path responsive to the clock chopping signal being inactive. The clock chopping signal is activated responsive to a mode control input signal being in a first state and deactivated responsive to either the mode control input signal being in a second state or a plurality of clock enable signals being inactive. In one or more embodiments, a multimode, uniform-latency CGC is included in a microprocessor for providing pulse clock signals to inter-stage pulsed sequential storage elements when operating in a timing sensitive mode and for providing phase clock signals to the inter-stage pulsed sequential storage elements when operating in a timing insensitive mode. ® KIPO & WIPO 2009
