摘要： A data processing system composites graphics content, generated by an application program running on the data processing system, to generate image data. The data processing system stores the image data in a first framebuffer and displays an image generated from the image data in the first framebuffer on an internal display device of the data processing system. A scaler in the data processing system performs scaling operations on the image data in the first framebuffer, stores the scaled image data in a second framebuffer and displays an image generated from the scaled image data in the second framebuffer on an external display device coupled to the data processing system. The scaler performs the scaling operations asynchronously with respect to the compositing of the graphics content. The data processing system automatically mirrors the image on the external display device unless the application program is publishing additional graphics content for display on the external display device.

摘要： An operating system creates one or more virtual display interfaces for communication of display data and user input events between the application layer and one or more virtual display devices. The one or more virtual display devices are not physically connected to the computing system managed by the operating system. One or more applications are executed in an application layer. At least one of the one or more applications communicates display data to and receives user input events from at least one of the one or more display devices using at least one of the display interfaces. At least one other of the one or more applications communicates display data to and receives user input events from at least one of the one or more virtual display devices using at least one of the one or more virtual display interfaces.

摘要： Systems, computer readable media, and methods for a unified programming interface and language are disclosed. In one embodiment, the unified programming interface and language assists program developers write multi-threaded programs that can perform both graphics and data-parallel compute processing on GPUs. The same GPU programming language model can be used to describe both graphics shaders and compute kernels, and the same data structures and resources may be used for both graphics and compute operations. Developers can use multithreading efficiently to create and submit command buffers in parallel.

摘要： A computing system that supports the use of multiple displays in display mirroring mode and extended display mode may automatically determine a display mode in which to configure the system (with little or no user input) based on various characteristics of the displays in the system. For example, the system may determine that a television, projector, or other presentation type display is connected in the system, and in response, may determine that the system should be configured in a display mirroring mode, rather than in an extended display mode. The system may also determine that the presentation type display is the preferred display, and may render image content in a best (or preferred) mode for that display using its native resolution, aspect ratio or color profile. The system may then scale the rendered image content for display on other (non-preferred) displays, such as an internal display, without re-rendering it.

摘要： A logical framebuffer may identify pixels areas or blocks of an image that have changed between successive frames. The pixel values of these identified areas may be copied and/or scaled from more recent frames and merged into older frames stored in scanout buffers of an image display system to update older buffers. The logical framebuffer may compare image data at a resolution that is greater than or equal to the resolution of the scanout buffers. Scaling may be used to downscale changed pixel areas frames stored at the higher resolution of logical framebuffer that are to be copied into older frames at the lower resolution of the scanout buffers to update the older frames. Changed pixel areas may also be copied from a newer frame buffered at the lower resolution after the older frame. Latency may be reduced. Image processors, display systems, and methods are provided.
