ALTERING OPERATING FREQUENCY AND VOLTAGE SET POINT OF A CIRCUIT IN RESPONSE TO THE OPERATING TEMPERATURE AND INSTANTANEOUS OPERATING VOLTAGE OF THE CIRCUIT

摘要

Setting the clock frequency provided to a load circuit, such as a microprocessor, as function of the operating temperature and supply voltage of the load circuit, and setting the supply voltage as a function of the operating temperature of the load circuit. The load circuit can be safely operated above the frequency which would be the limit if the load circuit were operating at the maximum test temperature. At the given operating temperature, the supply voltage can be raised to permit even higher frequency operation, or lowered to reduce power.
