Latest Patents

One of his latest patents is titled "Multi-mode texture sampler for flexible filtering of graphical texture data." This invention introduces a texture sampler that fetches and reduces texture data using a filter accumulator, which is suitable for providing a weighted average across various filter footprints. The multi-mode texture sampler is versatile; it offers a wide variety of footprints in both separable and non-separable filter modes and enables filtering with footprints significantly wider than the typical bi-linear (2×2 texel) footprint. Additionally, the texture sampler generates sub-sample addresses to accommodate desired footprints, utilizing multi-texel units like 2×2 texel quads for efficient filtering. The implementation also includes caching filter coefficients from coefficient tables stored in memory.
