ABSTRACT:
The microprocessor unit of a system implemented using metal-oxide-silicon (MOS) technology, is driven by a variable-frequency clock. The microprocessor controls the clock frequency based on the present rate of required microprocessor activity. By driving the microprocessor unit at a lower clock frequency when such activity rate is low, the energy dissipated by the microprocessor unit is reduced due to the MOS power-frequency characteristic.
