Abstract:
An efficient and effective compiler data prefetching technique is disclosed in which memory accesses may be prefetched are represented in linear induction expressions. Furthermore, indirect memory accesses indexed by other memory accesses of linear induction expressions in scalar loops may be prefetched.
