WebThe prefetcher recognizes a sequence of data cache misses at a fixed stride pattern that lies in 32 cache lines, plus or minus. Any intervening stores or loads that hit in the data cache do not interfere with the recognition of the cache miss pattern. Up to twelve independent streams can be handled by the prefetcher.
