Drive control system for microprocessor with conditional power saving.

摘要

A drive control system for a microprocessor comprises a drive condition varying means for varying a drive condition of the microprocessor for varying a processing speed and a power consumption in mutually related manner, an operational state dependent control means for monitoring operational state of the microprocessor and controlling the drive condition varying means for adapting the processing speed to the operational state, and a temperature dependent control means for monitoring a temperature condition of the microprocessor for overriding the operational state dependent control means for lowering the power consumption of the microprocessor when the temperature condition of the microprocessor higher than a predetermined criterion temperature is detected.
