Method and apparatus for filtering prefetches to provide high prefetch accuracy using less hardware |
摘要 |
In general, the PBVT structure provides an effective method of filtering a stream of hardware generated prefetches by eliminating prefetch addresses that have proven to be inaccurate in the past. When compared to a design that uses a PFB of equal number of entries, the PBVT along with a small PFB provides virtually equivalent prefetch accuracy and miss rate reduction while using much less hardware area (97% less data storage space for a 1024-entry PFB case).
