【 摘 要 】

References(8)The traversal process in accelerated ray tracing algorithms requires many memory transactions of an acceleration structure. We present a pre-fetching system to pre-load potential node data into a cache. Experimental results show that the proposed scheme increases the performance of a cache system by reducing the cache miss rate.
