Patent ID: 7282966

Claim:
An apparatus, including: at least one sensor including a voltage sensor coupled to a microprocessor to generate a sense signal related to at least one of a voltage sensed at the microprocessor or a temperature sensed at the microprocessor; a control module coupled to the at least one sensor to generate a control signal responsive to the sense signal to control a selection of a clock signal to be input to the microprocessor; a look-up module coupled to the control module to associate the at least one of the voltage sensed at the microprocessor or the temperature sensed at the microprocessor to at least one of a desired voltage, a desired temperature, or a desired frequency of operation of the microprocessor; and a selector coupled to the control module to select the clock signal from a plurality of clock signals associated with a plurality of clocks to cause the microprocessor to operate at a rate such as to drive at least one of the voltage sensed at the microprocessor toward the desired voltage or the temperature sensed at the microprocessor toward the desired temperature.
