Abstract
An accelerometer or other motion sensor is used to provide power to an entire processor system such that the processor does not need to be powered to process the motion signals for initial power-on control. After the processor system is powered on, the processor system may receive and process motion signals as normal, including, for example, performing various power-control functions such as power-down of certain components or the entire system upon detection of a lack of motion for a predetermined amount of time.
