Abstract: The invention provides for cache organization of texture information and a method and apparatus for accessing cached texture information and an index for cached information. Texels are represented in two dimensions and stored in groups referred to as tiles. Cache is configured to contain multiple tiles of texture image data, each tile being stored as a line in the cache. A cache line can be multidimensional (e.g., two or three or more dimensions) and may be viewed as an identifiable storage element in the cache. Memory may consist of a plurality of cache lines. Direct mapped cache may be utilized wherein each DRAM location maps to a single cache line. A tag table contains the tag information for all tiles currently stored in cache. A portion of the texel information may be utilized as an index assigned to a specific cache line. Another portion of the tag information identifies the tile currently stored in cache.

Abstract: A low cost high performance three dimensional (3D) graphics system can model a world in three dimensions and project the model onto a two dimensional viewing plane selected based on a changeable viewpoint. The viewpoint can be changed on an interactive, real time basis by operating user input controls such as game controllers. The system rapidly produces a corresponding changing image (which can include animated cartoon characters or other animation for example) on the screen of a color television set. The richly featured high performance low cost system gives consumers the chance to interact in real time inside magnificent virtual 3D worlds to provide a high degree of image realism, excitement and flexibility. An optimum feature set/architecture (including a custom designed graphics/audio coprocessor) provides high quality fast moving 3D images and digital stereo sound for video game play and other graphics applications.
