4. Technical Presentation

Tetsugo Inada	Title Compressed Lossless Texture Representation and Caching Abstract We present a block-oriented lossless texture compression algorithm based on a simple variable-bitrate differencing scheme. A B-tree index enables both random access and efficient O(1) memory allocation without external fragmentation. Textures in our test suite compressed to between 6% and 95% of their original sizes. We propose a cache architecture designed to support our compression scheme. Cycle-accurate simulation shows that this cache architecture consistently reduces the external bandwidth requirements as well as the storage size without significantly affecting latency

We present a block-oriented lossless texture compression algorithm based on a simple variable-bitrate differencing scheme. A B-tree index enables both random access and efficient O(1) memory allocation without external fragmentation. Textures in our test suite compressed to between 6% and 95% of their original sizes. We propose a cache architecture designed to support our compression scheme. Cycle-accurate simulation shows that this cache architecture consistently reduces the external bandwidth requirements as well as the storage size without significantly affecting latency
