Abstract

Abstract A control circuit for a computer component circuit which includes oscillator apparatus for providing square wave pulses at a prescribed frequency, gating apparatus for providing the square wave pulses at an output terminal for use as a clock for the component circuit, timing apparatus for sensing a period during which the component circuit has not performed an operation, and apparatus for disabling the gating apparatus for providing the square wave pulses at an output terminal.
