摘要： The current invention involves new systems and methods for reorganizing a texture sampling order that is used to read texels from a texel cache. When anisotropic filtering is used to process the texels read from the texel cache, the texels are read in an order based on a major axis alignment. Reorganizing texture sampling order to use the order based on the major axis alignment results in improved texel cache locality, thereby improving texel cache performance.

摘要： A method for implementing LOD (level of detail) filtering in a cube mapping application. The method includes accessing a first sample and a second sample for a cube map. A cube map path is computed between the first sample and the second sample. A distance is computed between the first sample and the second sample, wherein the distance is measured using the cube map path. LOD filtering is then implemented by using the distance between the first sample and the second sample.

摘要： Shortening a footprint is a technique to reduce the number of texture samples anisotropically filtered to determine a texture value associated with a graphics fragment. Reducing the number of texture samples anisotropically filtered reduces the number of texture samples read and simplifies the filter computation. Programmable knobs are used to shorten the footprint of a pixel in texture space thereby reducing the number of texture samples used during anisotropic filtering. These knobs permit a user to determine a balance between improved texture map performance and anisotropic texture filtering quality.

摘要： Trilinear optimization is a technique to reduce the number of texture samples used to determine a texture value associated with a graphics fragment.

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 used for bilinear texture filtering may also be used to perform font filtering. Font data stored as a texture is read from memory in blocks that are coarsely aligned. Font alignment units may be used to provide a finely aligned region of the font data within a font filter footprint. The finely aligned region is then filtered using bilinear filtering to produce font coverage information representing a grayscale value for a pixel. Using existing bilinear filtering engines in conjunction with font alignment and sample units reduces the need for having a specific engine to perform each of the font filtering operations, possibly saving die area in a graphics system.
