PAGE AWARE PREFETCH MECHANISM

A processor includes a prefetch aware prefetch unit having a storage with a number of entries, and each entry corresponds to a different prefetch data stream. Each entry may be configured to store information corresponding to a page size of the prefetch data stream, along with, for example, an address corresponding to the prefetch data stream. For each entry, the prefetch unit may be configured to determine whether a prefetch of data in the data stream will cross a page boundary associated with the data stream based upon the page size information.
