ABSTRACT:
A microprocessor control circuit continuously monitors core logic operating temperature and detects it has risen above a first temperature and responsively iteratively controls a system voltage source to output a next lower one of its N output voltage levels and controls clock generation circuitry of the microprocessor to output a lower one of its M core clock signal frequencies as necessitated by a transition to the next lower output voltage level until the temperature drops below the first temperature. The control circuit detects that the temperature has dropped below a second temperature and responsively iteratively controls the voltage source to output a next higher output voltage level and controls the clock generation circuitry to output a higher core clock signal frequency as permitted by the next higher output voltage level until the operating temperature rises above the second temperature. The M frequencies comprise a highest, lowest, and plurality of intermediate frequencies.
