Circuitry for optimization of power consumption in a system employing multiple electronic components, one of which is always powered on

摘要

Abstract Circuitry for conserving power in a system employing multiple electronic components of which a first electronic component operates at a first frequency and is 5 continuously powered on by a power source. The system further includes a second electronic component operating at a second frequency different than that of the first frequency of the first electric component, the second electronic component being maintained in a powered off state in which no energy whatsoever is consumed by the second electronic component until energized in response to a power enabling signal 10 generated by the first electronic component based on demand of the particular function to be performed by the second electronic component. The first and second electronic components may be processors, wherein the frequency of the first processor is lower than that of the second processor.
