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.

摘要: A method for trafficking data based at least in part on a power condition of a system resource. In one embodiment of the invention, a data trafficking device initiates data traffic in response to a detecting of an indication of the power condition. In another embodiment of the invention, the detected indication is independent of any data traffic of the data trafficking device.

摘要: A scheme to facilitate deterministic thermal management by having either device connected via a link to generate a thermal management request based on one device's thermal capability and the present conditions. The request is transmitted over the link to the other device with a specific sleep period. Consequently, the receiving device responds with an acknowledgement within a pre-configured or pre-agreed response time.

摘要: Some embodiments describe techniques that relate to hybrid graphics display power management. In one embodiment, data corresponding to one or more image frames of a video stream are stored in a local frame buffer. A display device (e.g., an LCD) may then be driven based on the stored data in the local frame buffer or a video stream from a graphics controller. Other embodiments are also described.

摘要: Bandwidth modulation may enable most of the display data-path to operate at a lower performance level to reduce power consumption by using compression as part of the display engine capability. Use of compression may afford a bit rate reduction and/or lane width reduction on the display interface to support high resolution display. With the bit rate and/or lane reduction and selective use of a refresh rate reduction, this technique can be used to lower the power consumption of the display data-path.
摘要翻译: 带宽调制可以使得大多数显示数据路径在较低的性能水平下运行,以通过使用压缩作为显示引擎能力的一部分来降低功耗。 使用压缩可以在显示器接口上提供比特率降低和/或通道宽度减少以支持高分辨率显示。 利用比特率和/或通道减少和选择性地使用刷新率降低,该技术可以用于降低显示数据路径的功耗。

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.
