Computer Architecture —— Advanced Cache 高级缓存优化（四）

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. WebThe data cache unit (DCU) prefetcher, also known as next-line prefetcher [52], attempts to automatically prefetch a single, subsequent cache line. Data prefetch logic (DPL), i.e., the adjacent prefetcher, regards data as 128-bytes aligned blocks. A cache miss to one of the two cache lines in this block will trigger a prefetch to the pair line.
