Abstract
The ability to stop a clock in a CMOS peripheral device or other CMOS IC, and reliably restart it based on an asynchronous event, provides the basis for considerable power savings. In a computer system 20 an interface component 10 has a clock restart circuit 100. The restart circuit 100 includes a series of D-type CMOS flip-flops (110, 112, 118) that are initially set in their zero state. A logic OR gate 120 receives the microprocessor clock and the complimentary output of the last flip-flop to provide a reliable, restarted clock signal for the interface component 10 and its peripherals 26.
