Abstract:
Prefetching is permitted to cross from one physical memory page to another. More specifically, if a stream of access requests contains virtual addresses that map to more than one physical memory page, then prefetching can continue from a first physical memory page to a second physical memory page. The prefetching advantageously continues to the second physical memory page based on the confidence level and prefetch distance established while the first physical memory page was the target of the access requests.
