摘要：
A microprocessor cache configuration for reducing database cache misses and improving the processing speed, comprising a level-1 data cache, and a page prefetch cache. The page prefetch cache is adjacent the level-1 data cache. The page prefetch cache is configured to receive and store one or more database pages. Additionally, a page prefetch instruction provides the database pages to the page prefetch cache. The page prefetch instructions are generated by a compiler or by developer software.
