An efficient texture cache for programmable vertex shaders

Vertex texturing is state-of-the-art functionality of vertex. Thus, traditional texture caches used in RE are not the 3D geometry processor. However, it aggravates the always applicable to a vertex texture. bandwidth problem between 3D graphics hardware and external memory besides the per-pixel texturing. Since vertex In this paper, we investigate the environment of the texturing does not guarantee high locality all over the texture vertex texturing and propose a novel caching scheme for the data unlike the per-pixel texturing, we propose a novel caching vertex texturing. The proposed caching scheme adaptively scheme that adaptively adjusts its operation by estimating the adjusts the cache operation by estimating the amount of the amount of the locality of access pattern. The proposed cache locality of texture accesses, and achieves 27.0% reduction of improves 27.0% of texture loading performance for general average access cycles compared with a conventional texture test scenes with on...
