摘要： A texture data reading apparatus includes a cache memory including a plurality of read ports and a plurality of regions to store pixel texture data. An address comparator includes a plurality of input ports to receive incoming pixels, wherein the address comparator compares the memory addresses associated with the incoming pixels to determine which regions of cache memory are accessed. A cache lookup device accesses new texture data from the cache memory for the incoming pixels in the same clock cycle in response to the number of memory regions accessed being less than or equal to the number of cache memory read ports.

摘要： For a given texture address, a texture sampler fetches and reduces texture data with a filter accumulator suitable for providing a weighted average over a variety of filter footprints. A multi-mode texture sampler is configurable to provide both a wide variety of footprints in either a separable or non-separable filter modes and allow for a filter footprint significantly wider than the bi-linear (2×2 texel) footprint. In embodiments, sub-sample addresses are generated by the texture sampler logic to accommodate a desired footprint. The sub-sample addresses may be generated and sequenced by multi-texel units, such as 2×2 texel quads, for efficient filtering. In embodiments, filter coefficients are cached from coefficient tables stored in memory.

摘要： A method for anisotropic filtering is provided herein. The method includes computing an anisotropic filter with a major-axis and a minor-axis for a pixel to be displayed on screen-space, wherein the anisotropic filter is to be applied to corresponding MIPs on a texture map. The method includes varying the length of the major-axis of the anisotropic filter based on the angle of the major-axis of anisotropy with respect to the screen space. The method includes determining a number of texels from the texture map that are to be sampled in the anisotropic filter based on the length of the modified major-axis. The method includes determining the color of the pixel based on the texels sampled in the anisotropic filter.
