  • Multi mode texture sampler for flexible filtering of graphical texture data
    Patent number: 10546413
    Abstract: 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.
