Abstract
A system, apparatus, and method are disclosed for storing predictions as well as examining and using one or more caches for anticipating accesses to a memory. In one embodiment, an exemplary apparatus is a prefetcher for managing predictive accesses with a memory. The prefetcher can include a speculator to generate a range of predictions, and multiple caches. For example, the prefetcher can include a first cache and a second cache to store predictions. An entry of the first cache is addressable by a first representation of an address from the range of predictions, whereas an entry of the second cache is addressable by a second representation of the address. The first and the second representations are compared in parallel against the stored predictions of either the first cache and the second cache, or both.
