摘要： A display pipe is configured to generate output frames for display. Additionally, the display pipe may be configured to compress an output frame and write the compressed frame back to memory responsive to detecting static content in successive output frames. The display pipe may also be configured to determine to selectively allow write-back logic to operate when doing so will not cause a pixel underrun to the display. If an underrun might occur, write-back logic is temporarily disabled. If write-back is successful, the display pipe may read the compressed frame from memory for display instead of reading the source frames for compositing and display.

摘要： An overdrive engine generates output frames to be used to drive a display from input frames to be displayed. Each output frame is generated on a region by region basis from the corresponding regions of the input frames. If it is determined that an input frame region has changed significantly since the previous version(s) of the input frame, an overdriven version of the input frame region is generated for use as the corresponding region in the output frame. On the other hand, if it is determined that the input frame region has not changed since the previous version of the input frame, then the new input frame region is used without performing any form of overdrive process on it for the corresponding region in the output frame.

摘要： A system displays graphics with an in-vehicle information system and a mobile electronic device. The in-vehicle information system receives encoded graphics data from the mobile electronic device and displays the encoded data with a graphical output device. The mobile electronic device executes program instructions to generate a series of graphics frames that are generated at a first frame rate and stored in an off-screen frame buffer in the mobile electronic device, generate encoded data corresponding to the series of graphics frames, and transmit the encoded data to the in-vehicle information system.

摘要： A software application executing on at least one processor may output a video at a frame rate for display at a display device. The at least one processor may synchronize a refresh rate of the display device displaying the video to the frame rate of the video. In response to detecting a potential delay in displaying, at the display device, a frame of the video to be output by the software application, the at least one processor may time-shift at least one of: compositing of the frame and refreshing of the display device to mitigate the potential delay in displaying, at the display device, the frame of the video to be output by the software application.

摘要： One embodiment of the present invention sets forth a graphics subsystem configured to implement distributed tiled caching. The graphics subsystem includes one or more world-space pipelines, one or more screen-space pipelines, one or more tiling units, and a crossbar unit. Each world-space pipeline is implemented in a different processing entity and is coupled to a different tiling unit. Each screen-space pipeline is implemented in a different processing entity and is coupled to the crossbar unit. The tiling units are configured to receive primitives from the world-space pipelines, generate cache tile batches based on the primitives, and transmit the primitives to the screen-space pipelines. One advantage of the disclosed approach is that primitives are processed in application-programming-interface order in a highly parallel tiling architecture. Another advantage is that primitives are processed in cache tile order, which reduces memory bandwidth consumption and improves cache memory utilization.

摘要： An image adjusting method for extending vertical blanking intervals of an image signal is provided. Using the image adjusting method, an adjusted image signal is synchronized with an image signal before the adjustment to prevent image delay. The image adjusting method comprises providing a first image signal having a first data enable signal, wherein the first data enable signal has a first data enable duration; and generating a second data enable signal having a second data enable duration. The first and second data enable durations correspond to a same image frame of an image signal, and the second data enable duration substantially overlaps the first data enable duration.
