    摘要： Methods of reducing power consumption in a computing device are described in which file sharing applications which are running in the background are offloaded onto a lower power subsystem and the rest of the computing device can be put into a low power state. The lower power subsystem runs application stubs which autonomously execute a subset of the operations performed by a file sharing application which was previously running on the computing device. Before the rest of the computing device goes into the low power state, application state information is passed to the lower power subsystem for use by the application stubs. In an example, the application stub may continue to download files whilst the rest of the computing device is in standby or is shutdown and the application state information may include details of the files that are to be downloaded.

    摘要： Methods of reducing power consumption of networked devices are described. When a main processor and associated hardware in a computing device is powered down, a processing element, with lower power consumption than the main processor, performs networking functions on behalf of the main processor. The processing element monitors events and wakes the main processor when defined criteria are satisfied. In an embodiment, these network functions may be to maintain existing network connections and/or establish new network connections and the defined criteria may relate to messages received by the device which are analyzed by the processing element running the application layer code and these criteria may be configurable by a user of the device.

    摘要： Embodiments provide implementations for estimating a test application's energy usage on a target device based on execution of the test application. Resource usage associated with the execution of the test application is measured. The measured resource usage is input into a power model of the target device to estimate the energy that the test application uses when executed on the target device. An emulation system is configured to execute the test application in a virtual execution environment using resource scaling and simulated target device application programming interfaces to substantially simulate the corresponding capabilities of the target device.
