摘要： A unified compression/decompression architecture is disclosed for reducing memory bandwidth requirements in 3D graphics processing applications. The techniques described erase several distinctions between a texture (compressed once, and decompressed many times), and buffers (compressed and decompressed repeatedly during rendering of an image). An exemplary method for processing graphics data according to one or more embodiments of the invention thus begins with the updating of one or more tiles of a first image array, which are then compressed, using a real-time buffer compression algorithm, to obtain compressed image array tiles. The compressed image array tiles are stored for subsequent use as a texture. During real-time rendering of a second image array, the compressed image array tiles are retrieved and decompressed using a decompression algorithm corresponding to the buffer compression algorithm. The decompressed image array tiles are then applied as a texture to one or more primitives in the second image array.

摘要： First (710) and (720) second codewords are determined, based on first feature vector components of the image elements (610) in an image block (600), as representations of a first (10) and second (12) component value. Third (730) and fourth (740) codewords are determined, based on second vector components, as representations of a third (20) and fourth (22) component value.

摘要： Methods and apparatus are disclosed for the processing of frame buffer data, such as color buffer data, in graphics processing applications. Although more generally applicable, these methods and apparatus are particularly useful in real-time, polygon-based, 3D rendering applications. An exemplary method for processing graphics data according to one or more embodiments of the invention begins with the retrieval, from a buffer, of pixel values corresponding to a tile of two or more pixels, and with the updating of one or more of those updated pixel values. The updated pixel values are selectively compressed using a lossy compression operation or a lossless compression operation, based on an accumulated error metric value for the tile. If lossy compression is used, then the accumulated error metric value for the tile is updated; in either event, the compressed pixel values are stored in the frame buffer for further processing. With this approach, the accumulated error caused by successive, or tandem, compression operations may be limited to a pre-determined maximum.

摘要： A graphics processing circuit for rendering three-dimensional graphics data is disclosed. The circuit includes pipelined graphics processing stages, wherein each of two or more of the stages is configured to process at least one of graphics primitives, vertices, tiles, and pixels, according to a stage-specific error budget. Depending on its error budget, each of these stages may select a high- or low-precision calculation, select between lossless and lossy compression, adjust the compression ratio of a variable lossy compression algorithm, or some combination of these approaches. The circuit further comprises a global error-control unit configured to determine error budgets for each of the two or more stages, based on at least one of error data received from the two or more stages, predetermined scene complexity data, and user-defined error settings, and to assign the error budgets to the graphics processing stages. Corresponding methods for processing graphics data are also disclosed.

摘要： Techniques are described that can delay or even prevent use of memory to store triangles associated with tiles as well as processing resources associated with vertex shading and binning triangles. The techniques can also provide better load balancing among a set of cores, and hence provide better performance. A bounding volume is generated to represent a geometry group. Culling takes place to determine whether a geometry group is to have triangles rendered. Vertex shading and association of triangles with tiles can be performed across multiple cores in parallel. Processing resources are allocated for rasterizing tiles that have been vertex shaded and binned triangles over tiles that have yet to be vertex shaded and binned triangles. Rasterization of triangles of different tiles can be performed by multiple cores in parallel.
