Abstract: This application relates to techniques that adjust the sleep states of a computing device based on proximity detection and predicted user activity. Proximity detection procedures can be used to determine a proximity between the computing device and a remote computing device coupled to the user. Based on these proximity detection procedures, the computing device can either correspondingly increase or decrease the amount power supplied to the various components during either a low-power sleep state or a high-power sleep state. Additionally, historical user activity data gathered on the computing device can be used to predict when the user will likely use the computing device. Based on the gathered historical user activity, deep sleep signals and light sleep signals can be issued at a time when the computing device is placed within a sleep state which can cause it to immediately enter either a low-power sleep state or a high-power sleep state.

Abstract: An apparatus is configured to calculate consumption power of a processor caused by execution of a program, based on sampling data acquired by event-based sampling. The apparatus determines whether the processor is in an idle state, by using the sampling data of a clock event, where the clock event is an event which generates an interrupt at fixed time intervals when the processor is not in the idle state, and which generates the interrupt when a state of the processor changes from the idle state to a non-idle state. In a case where the processor is in the idle state, the apparatus calculates a first amount of consumption power of the processor in the idle state, based on a second amount of consumption power calculated using a consumption power model and a third amount of consumption power included in the sampling data.
