  • Tracking and eliminating bad prefetches generated by a stride prefetcher
    Patent number: 9047173
    Abstract: A method, an apparatus, and a non-transitory computer readable medium for tracking prefetches generated by a stride prefetcher are presented. Responsive to a prefetcher table entry for an address stream locking on a stride, prefetch suppression logic is updated and prefetches from the prefetcher table entry are suppressed when suppression is enabled for that prefetcher table entry. A stride is a difference between consecutive addresses in the address stream. A prefetch request is issued from the prefetcher table entry when suppression is not enabled for that prefetcher table entry.
