摘要： A method, medium, and system are provided for a generic surface manager which allows graphics surfaces generated according to various existing and/or new graphics protocols to be rendered by a graphics consumer. The generic surface manager functions as an interface between a graphics consumer and one or more applications that generate graphics surfaces. Support is provided for various existing graphics protocols and the generic surface manager can be easily modified to accept surfaces generated according to new graphics protocols. An extensible system is thereby provided that can support a variety of graphics protocols without requiring modifications to be made to the graphics consumer.

摘要： Methods for mapping color data having at least one color associated therewith to an output device based on an input-device profile and an output-device profile, each profile having a tone curve and a color matrix, are provided. In one embodiment, the method includes receiving color data from an input device and determining whether the color data is in a linear space. If it is determined that the color data is not in a linear space, the method further includes applying the tone curve of the input device profile to the color data to convert it into a linear space. The method further includes converting the color(s) associated with the color data from the input linear space to an output linear space by applying the color matrix of the input device profile and the inverse color matrix of the output device profile to create color-converted image data.

摘要： Video frame buffers are controlled using a sequence of new-frame-indicators (e.g., FLIP) and no-new-frame-indicators (e.g., NOFLIP) in a frame indicator queue that is accessed with each display refresh. Video samples are loaded into a chain of video frame buffers that is “rotated” during the vertical blanking signal of the display to swap an old frame buffer out for a new frame buffer. The rotations of the frame buffer chain are controlled based on the frame indicators in the frame indicator queue to present new video samples to the display in a regular pattern, thereby providing smooth video playback.
摘要翻译：在每个显示刷新访问的帧指示符队列中，使用新帧指示符序列（例如，FLIP）和无新帧指示符（例如，NOFLIP）来控制视频帧缓冲器。视频样本被加载到视频帧缓冲器链中，该视频帧缓冲器在显示器的垂直消隐信号期间被“旋转”，以将新的帧缓冲器交换出来用于新的帧缓冲器。基于帧指示符队列中的帧指示符来控制帧缓冲链的转动，以规则模式将新的视频样本呈现给显示器，从而提供平滑的视频回放。

摘要： A method and system for minimizing an amount of data needed to test data against subarea boundaries in spatially composited digital video. Spatial compositing uses a graphics unit or pipeline to render a portion (subarea) of each overall frame of digital video images. This reduces the amount of data that each processor must act on and increases the rate at which an overall frame is rendered. Optimization of spatial compositing depends on balancing the processing load among the different pipelines. The processing load typically is direct function of the size of a given subarea and a function of the rendering complexity for objects within this subarea. Load balancing strives to measure these variables and adjust, from frame to frame, the number, sizes, and positions of the subareas. The cost of this approach is the necessity to communicate, in conjunction with each frame, the graphics data that will be rendered. Graphics data for a frame is composed of geometry chunks. Each geometry chunk is defined by its own bounding region, where the bounding region defines the space the geometry chunk occupies on the compositing window. Only the parameters that define the bounding region are communicated to each graphics unit in conjunction with the determination of which graphics unit will render the geometry chunk defined by the bounding region. The actual graphics data that comprises the geometry chunk is communicated only to those geometry units that will actually render the geometry chunk. This reduces the amount of data needed to communicate graphics data information in spatially composited digital video.

摘要： An enhanced graphics pipeline is provided that enables common core hardware to perform as different components of the graphics pipeline, programmability of primitives including lines and triangles by a component in the pipeline, and a stream output before or simultaneously with the rendering a graphical display with the data in the pipeline. The programmer does not have to optimize the code, as the common core will balance the load of functions necessary and dynamically allocate those instructions on the common core hardware. The programmer may program primitives using algorithms to simplify all vertex calculations by substituting with topology made with lines and triangles. The programmer takes the calculated output data and can read it before or while it is being rendered. Thus, a programmer has greater flexibility in programming. By using the enhanced graphics pipeline, the programmer can optimize the usage of the hardware in the pipeline, program vertex, line or triangle topologies altogether rather than each vertex alone, and read any calculated data from memory where the pipeline can output the calculated information.
