Abstract
For a given texture address, a multi-mode texture sampler fetches and reduces texture data with a multi-mode 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 and allow for a filter footprint significantly wider than the bi-linear (2×2 texel) footprint. In embodiments, filter coefficients specifying a weighting for each texel in a flexible footprint are cached from coefficient tables stored in memory. Techniques and systems are provided for dynamic allocation, update and handling of weighting coefficient tables as resources independent of sampler state.
