Abstract

A computer-implemented method to prefetch non-sequential instruction addresses (I/A) includes, determining, by a prefetch system, a first access attempt of a first I/A in a cache is a first miss, wherein the first I/A is included in a string of I/A's. The method further includes storing the first I/A in a linked miss-to-miss (LMTM) table. The method also includes determining a second access attempt of a second I/A in the cache is a second miss, wherein the second I/A is included in the string of I/A's. The method includes linking, in the LMTM table, the second miss to the first miss. The method also includes prefetching, in response to a third access attempt of the first I/A, the second I/A in the cache.
