Abstract
A prefetch mechanism using prefetch attributes is disclosed. In one aspect, an explicit request for data stored in a memory is provided, and a prefetch attribute in a page table entry associated with the explicit request is examined to determine whether to provide one or more prefetch requests based on the prefetch attribute. Another aspect includes determining dynamic prefetch attributes for use in prefetching data, in which prefetch attributes are adjusted based on memory access requests that target next sequential blocks of memory relative to the most recent previous access in a page of memory.
