The primer of hardware prefetching
WebbHardware prefetchers can generally only handle very regular access patterns. The cost of prefetching data that isn't used can be high, so processor designers have to be … WebbPrefetching, i.e., exploiting the overlap of processor com-putations with data accesses, is one of several approaches for tolerating memory latencies.
