Abstract
A method and apparatus for mapping some software prefetch instructions in a microprocessor system to a modified set of hardware prefetch instructions and executing the software prefetch by invoking the corresponding modified hardware prefetch instruction. For common software prefetch access patterns, by mapping the software prefetches to hardware, improved prefetching can be achieved without the need for additional hardware.
