In one embodiment, a graphics processing unitmay support a logical resource using a physical tile poolfor sparse data sets. The graphics processing unitmay allocate a physical memory allocation into a primary physical tile pool. The graphics processing unitmay define a mapping for a logical tile setfor a logical resource. The graphics processing unitmay selectively map a primary logical tileof the logical tile setto a primary physical tileof the primary physical tile pool

Hardware-accelerated resource tiling

A procedural texture relates texel coordinates to color values through an arbitrary function, herein called a texel shader. The procedural texture is defined by a dimension, size, texel format and the texel shader. Texel coordinates are an input to the texel shader, which generates a color value for those texel coordinates. A renderer can be implemented either in hardware, such as part of a graphics processor, or in software as a computer program executed by a processor. The renderer samples from the procedural texture in response to texel coordinates, and evaluates the texel shader on demand. Filtering also can be applied automatically to results. The results of the texel shader invocations are stored in a texture cache to take advantage of spatial and temporal locality. Results are shared among threads, processes and the like through the texture cache.
