http://wiki.raptorcs.com/w/images/5/56/PowerISA_2.06_Stride_and_Prefetch.pdf WebMar 31, 2024 · Nesbit et al. [ 7] proposed a prefetching mechanism that employs an index table in conjunction with a global history buffer (GHB), and the delta correlation prefetching scheme that tracks cache events and memory requests information to find appropriate address deltas for generating the next prefetching candidates. WebData prefetching tolerates long memory access latency by predicting which data in memory is needed in the future and fetches it to the cache before it is accessed. To deal with irreg-ular access patterns that are hard to predict, one recent class of prefetching techniques that relies on a helper thread has been proposed [2, 10, 11, 13, 16, 19]. greenock town hall drop in
