Abstract: In one embodiment, a graphics processing unit 170 may support a logical resource using a physical tile pool 350 for sparse data sets. The graphics processing unit 170 may allocate a physical memory allocation into a primary physical tile pool 350. The graphics processing unit 170 may define a mapping for a logical tile set 300 for a logical resource. The graphics processing unit 170 may selectively map a primary logical tile 320 of the logical tile set 300 to a primary physical tile 360 of the primary physical tile pool 350.

Abstract: 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.
