Embodiments of the invention provide a look-aside-look-aside buffer (LLB) configured to retain a portion of the real addresses in a translation look-aside (TLB) buffer to allow prefetching of data from a cache. A subset of real address bits associated with an effective address may be retrieved relatively quickly from the LLB, thereby allowing access to the cache before the complete address translation is available and reducing cache access latency.
