    摘要: Techniques are described to monitor a level of graphics processing activity and control power usage based on the level. When no graphics processing activity is detected for a period of time, then a timing controller for a display device is instructed to capture a current image and repeatedly display the captured image. The graphics processing devices can be powered down. When graphics processing activity is detected, the graphics processing devices are powered up and the components used to capture an image and display the captured image are powered down.

    摘要: A host chipset heartbeat may be utilized, in some embodiments, to handle interrupts from external devices on a power efficient basis. The availability of the host chipset heartbeat may be signaled to external devices and those external devices may time their activities to a period of time when not only are resources available, but the assertion of the activity is advantageous because the host chipset is already transitioning from a lower power consumption state.
