Abstract:
1. A computing device having a processor that operates over a range of voltages, frequencies and temperatures, and over a range of processor usage levels, the computing device comprising: a variable frequency generator, coupled to the processor, that delivers a clock signal to the processor: a variable voltage power supply, coupled to the processor, that delivers voltage to the processor: a temperature sensor, that provides signals indicative of the temperature of the processor; and voltage supply level and clocking frequency management circuitry that is operable to adjust both the voltage delivered to the processor by the variable voltage power supply and the frequency of the signal provided by the variable frequency generator, the voltage supply level and clocking frequency management circuitry being operable to adjust the voltage provided by the variable voltage power supply based on the temperature indicated by the temperature sensor.
