NAPNOP circuit for conserving power in computer systems |
摘要 |
A NAPNOP circuit for decreasing energy consumption of all or a portion of a microprocessor based system which includes a delay circuit for inhibiting or slowing the output of the system clock pulses for a variable length of time equal to a multiple of N clock pulses where N is a positive integer. The NAPNOP circuit has an input element for inputting a STARTNAP signal which begins a nap period during which the system clock pulses are inhibited or slowed, a clock input device for providing a plurality of selectable clock pulses as inputs to the delay circuit for controlling the operation of the computer system, and a gate element for terminating the nap period.
