摘要： Data for data elements (e.g., pixels) can be stored in an addressable storage unit that can store a number of bits that is not a whole number multiple of the number of bits of data per data element. Similarly, a number of the data elements can be transferred per unit of time over a bus, where the width of the bus is not a whole number multiple of the number of bits of data per data element. Data for none of the data elements is stored in more than one of the storage units or transferred in more than one unit of time. Also, data for multiple data elements is packaged contiguously in the storage unit or across the width of the bus.

摘要： Systems and methods that decompress block compressed texture data may decompress the texture data while simplifying computations to reduce die area while maintaining the required accuracy. Reducing the die area permits more texture data to be decompressed in the same die area compared with a more accurate decompression, thereby increasing texture decompression throughput. Computations are simplified by combining denominators for linear interpolation with format conversion to decompress texture data components compressed using conventional block compression formats.

摘要： A scalable shader architecture is disclosed. In accord with that architecture, a shader includes multiple shader pipelines, each of which can perform processing operations on rasterized pixel data. Shader pipelines can be functionally removed as required, thus preventing a defective shader pipeline from causing a chip rejection. The shader includes a shader distributor that processes rasterized pixel data and then selectively distributes the processed rasterized pixel data to the various shader pipelines, beneficially in a manner that balances workloads. A shader collector formats the outputs of the various shader pipelines into proper order to form shaded pixel data. A shader instruction processor (scheduler) programs the individual shader pipelines to perform their intended tasks. Each shader pipeline has a shader gatekeeper that interacts with the shader distributor and with the shader instruction processor such that pixel data that passes through the shader pipelines is controlled and processed as required.

摘要： Hybrid sampling of pixels of an image involves generating shading values at multiple shading sample locations and generating depth values at multiple depth sample locations, with the number of depth sample locations exceeding the number of shading sample locations. Each shading sample location is associated with one or more of the depth sample locations. Generation and filtering of hybrid sampled pixel data can be done within a graphics processing system, transparent to an application that provides image data.

摘要： Systems and methods used for font filtering may also be used to perform texture blits. Texture data is read in blocks that are coarsely aligned. Font engines may be used to align the texture data as specified by a copy (blit) instruction to provide a finely aligned region of the texture data within a font filter footprint. The finely aligned region is then bilinearly filtered using a “nearest” mode to provide the bit aligned region of the texture map specified by the copy instruction.

摘要： Systems and methods for identifying pixels that are inside a two-dimensional path may be used to fill the path. The path is segmented and a slope direction is determined for each pixel that is covered by the segmented path. The slope directions are stored in a derivative mask that may be integrated for each scanline to produce a fill mask. The resulting fill mask indicates the pixels that are inside the two-dimensional path. The fill mask may be used to fill the path.

摘要： Circuits, methods, and apparatus that provide texture caches and related circuits that store and retrieve texels in a fast and efficient manner. One such texture circuit provides an increased number of bilerps for each pixel in a group of pixels, particularly when trilinear or aniso filtering is needed. For trilinear filtering, texels in a first and second level of detail are retrieved for a number of pixels during a clock cycle. When aniso filtering is performed, multiple bilerps can be retrieved for each of a number of pixels during one clock cycle.

摘要： Systems and methods for positioning bilinear texture samples to produce an anisotropically filtered texture mapped pixel may improve texture mapping performance and image quality. The bilinear texture samples are positioned along a major axis of anisotropy to approximate an elliptical footprint, ensuring that the bilinear texture samples span the entire axis of anisotropy without extending beyond the major axis of anisotropy. An additional bilinear texture sample or a pair of additional bilinear texture samples is positioned in the center of the axis of anisotropy dependent on the anisotropic ratio. The additional bilinear texture samples are weighed less than the other bilinear texture samples and all of the bilinear textures samples lie within the anisotropic footprint.

摘要： A pixel center position that is not covered by a primitive covering a portion of the pixel is displaced to lie within a fragment formed by the intersection of the primitive and the pixel. X,y coordinates of a pixel center are adjusted to displace the pixel center position to lie within the fragment, affecting actual texture map coordinates or barycentric weights. Alternatively, a centroid sub-pixel sample position is determined based on coverage data for the pixel and a multisample mode. The centroid sub-pixel sample position is used to compute pixel or sub-pixel parameters for the fragment.

摘要： Systems and methods for modifying the number of texture samples used to produce an anisotropically filtered texture mapped pixel may improve texture mapping performance. When the number of texture samples is reduced, fewer texels are read and fewer filtering computations are needed to produce a texture value for an anisotropic footprint. The number of texture samples is reduced based on the mip map level weight. The number of texture samples may also be modified using specific parameters for the coarse and/or fine mip map levels. The spacing between the texture samples along the major axis of anisotropy may be modified to improve image quality or texture cache performance.
