Abstract
Multi-mode texture filters suitable for performing both bilinear filtering based on a fractional texture address and generating a weighted average of a group of texel values based on predetermined texel weighting coefficients as dependent on a filter mode signal. In embodiments, the weighted average may be accumulated over a variety of filter footprints. In embodiments, multi-mode texture filter logic includes a plurality of flexible filter blocks. In further embodiments, a pair of flexible filter blocks staged with each performing one lerp phase in the bilinear filter mode while a pair of flexible filter blocks in the flexible filter mode generate a weighted average over a pair of texels of a texel quad. In embodiments, each flexible filter block has a same microarchitecture, enabling an efficient utilization in either bilinear filter or flexible filter mode.
