Abstract

A processor, comprising a monitor for measuring the relative amount of idle time within the processor, results of the measuring being used by the processor, depending upon the respective embodiment, to modify processor clock speed in response to a utilization percentage of the processor being below a preselected level, or to modify a clock speed of the processor to control a utilization percentage of the processor. Another embodiment discloses a processor, comprising a monitor for measuring the relative amount of idle time within the processor, results of the measuring being used by the processor for providing a signal for circuitry for controlling periods of time a processor clock is in an OFF state, the length of the periods of time said clock is in an OFF state being appropriate to allow the processor to operate at an efficient utilization percentage.
