Abstract
In a computer graphics system, a semiconductor chip used in performing texture mapping. Textures are input to the semiconductor chip. These textures are stored in a main memory. Cache memory is used to accelerate the reading and writing of texels. A memory controller controls the data transfers between the main memory and the cache memory. Also included within the same semiconductor chip is an interpolator. The interpolator produces an output texel by interpolating from textures stored in memory. The interpolated texel value is output by the semiconductor chip, thereby minimizing transmission bandwidth as well as redundant storage of texture maps in a multi-processor environment.
