A clock system

A low power management system and method of operating a processor at a plurality of clock frequencies comprising: providing clock signals to the processor, the clock signals being at a frequency determined by a variable supply voltage level; providing a first supply voltage level, thereby operating...

Beschreibung
Zusammenfassung:	A low power management system and method of operating a processor at a plurality of clock frequencies comprising: providing clock signals to the processor, the clock signals being at a frequency determined by a variable supply voltage level; providing a first supply voltage level, thereby operating the processor at a corresponding first clock frequency; determining the duration of time that the processor has been operating at the first clock frequency; and, upon determining that the processor has been operating at the first clock frequency for longer than predetermined duration, providing a second supply voltage level higher than the first supply voltage level, thereby operating the processor at a second clock frequency higher than the first clock frequency.
