Abstract: A microcomputer (104) having predetermined clock pulse frequency requirements receives pulses from a multiplying type frequency synthesizer (200) which utilizes a reference frequency less than the largest of the predetermined requirements. The synthesizer (200) is responsive to program instructions to generate clock pulse frequencies sufficient to satisfy the requirement for immediate execution of programmed tasks. As the execution requirements change, the synthesizer (200) responds to provide only the frequency required. Thus, the power dissipated by the entire microcomputer system is minimized.
