Abstract
A drive control system for a microprocessor comprises a switching circuit 5 for varying a drive condition of the microprocessor by varying a processing speed and a power consumption in mutually related manner, an operational state dependent control portion including a status judgment circuit 7, an address monitoring circuit 8, and an address detecting circuit 9, for monitoring the operational state of the microprocessor and controlling the switching circuit 5 for adapting the processing speed to the operational state, and a temperature dependent control portion comprising a temperature sensor 10 and a comparator 11, for lowering the power consumption of the microprocessor when the temperature condition of the microprocessor higher than a predetermined criterion temperature is detected.
