HIGH FREQUENCY, LOW POWER, CMOS CIRCUIT.

摘要

Power dissipation of a CMOS circuit such as a microprocessor is reduced by dynamically slowing down the microprocessor clock during selected system operations such as hold, wait, or AT peripheral bus access cycles. The microprocessor clock is slowed to its minimum allowable frequency with precise synchronous control to maintain the accuracy of high frequency clock edges and to prevent glitches or substandard pulse widths.
