EFFEKTBESPARENDE MICROCOMPUTER MED SYNTETISERET KLOKSIGNAL

摘要

A microcomputer 104 having predetermined clock pulse frequency requirements receives pulses from a frequency synthesizer 200 which utilizes a reference frequency less than the largest of the predetermined requirements. The synthesizer 200 is responsive to program instructions for the purpose of generating clock pulse frequencies sufficient to satisfy the requirement for immediate execution of programmed tasks. As the execution requirements change, the synthesizer 200 responds for the purpose of providing only the frequency required. Thus, the power used by the entire microcomputer system is minimized. <IMAGE>
