Abstract:
Circuits, methods, and apparatus that provide texture caches and related circuits that store and retrieve texels in an efficient manner. One such texture circuit can provide a configurable number of texel quads for a configurable number of pixels. For bilinear filtering, texels for a comparatively greater number of pixels can be retrieved. For trilinear filtering, texels in a first LOD are retrieved for a number of pixels during a first clock cycle, during a second clock cycle, texels in a second LOD are retrieved. When aniso filtering is needed, a greater number of texels can be retrieved for a comparatively lower number of pixels.
