Abstract
An adaptive cache indexing is proposed to reduce the memory bandwidth required for fetching texture image data by reducing the cache miss-rate through adaptive selection of index bits. By designing a texture mapping hardware including a texture cache, the number of cache miss and total cycles are examined for texture mapping from cycle-accurate HDL simulations on some test scenes. The number of cache miss and total cycles were reduced by 23% and 8.9% respectively by the adaptive cache indexing.
