A graphics system comprises a texture memory, a rendering engine, a sample buffer and a filtering engine. The rendering engine renders received primitives based on a render pixel array whose vertical and horizontal resolutions are dynamically programmable. The rendering engine determines render pixels that geometrically intersect a primitive. For each intersecting render pixel, a texture access may be required (if texture processing is turned on) to determine texture values. The texture values may be used to compute sample values at sample positions interior to the sample render pixel and the primitive. A controlling agent may decrease the vertical and horizontal resolutions of the render pixel array to control frame render time. The filtering engine may programmably generate virtual pixel centers covering the render pixel array. Any change in the render pixel resolutions may require an accommodating change in the virtual pixel array parameters.

A texture processing pipeline is configured to store decoded texture data within a cache unit in order to expedite the processing of texture requests. When a texture request is processed, the texture processing pipeline queries the cache unit to determine whether the requested data is resident in the cache. If the data is not resident in the cache unit, a cache miss occurs. The texture processing pipeline then reads encoded texture data from global memory, decodes that data, and writes different portions of the decoded memory into the cache unit at specific locations according to a caching map. If the data is, in fact, resident in the cache unit, a cache hit occurs, and the texture processing pipeline then reads decoded portions of the requested texture data from the cache unit and combines those portions according to the caching map.

The minimum-LOD values in the tracking table are accompanied by a coarse region access mask to associate a minimum LOD value with a specific region of the image or object. A clamping table contains LOD clamp values for each region and a region code that specifies the coarseness of the LOD associated with each region of the texture.
