Abstract

A technique for performing indirect data prefetching includes determining a first memory address of a pointer associated with a data prefetch instruction. Content of a memory at the first memory address is then fetched. A second memory address is determined from the content of the memory at the first memory address. Finally, a data block (e.g., a cache line) including data at the second memory address is fetched (e.g., from the memory or another memory).
