Power management based upon a prediction associated with an observed sequence of events

摘要

A computing device 10, which may be a multiprocessor device, comprising an event monitor 20 for observing events occurring within the computing device and a prediction component 22. The prediction component is configured to cause an operating parameter, which is preferably operating frequency, associated with the power consumption of the computing device to change if a sequence of events observed by the event monitor 20 corresponds to a pre-defined sequence associated with the change in the operating parameter. The device may also comprise a learning component 18 configured to learn the pre-defined sequence of events and to verify predictions by examining a processor load monitor 14 after the sequence of events has occurred. A score relating to the accuracy of the prediction may be associated with a sequence of events recorded by the learning component. The computing device is incorporated into a mobile phone.
