2003 (English)In: Proceedings of the ACM SIGGRAPH/EUROGRAPHICS conference on Graphics Hardware: San Diego, California, July 26-27, 2003, New York: Association for Computing Machinery (ACM), 2003, 76-83 p.Conference paper (Refereed)
This paper presents a cache-based memory architecture for volume graphics. We describe the memory organization and cache logic to implement a voxel cache based on 43 voxel blocks. We show an efficient prefetching scheme that increases the cache hit ratio to more than 98% in most cases. The performance of the memory system with different types of external memory is demonstrated by a cycle accurate C++ simulation. The VoxelCache memory architecture is designed to be easily adapted to different memory technologies, because all volume graphics specific parts of the memory system are encapsulated inside the on-chip cache. The design is targeted at implementation on off-the-shelf reconfigurable hardware.
