Hardware prefetcher要开启吗
Webthis paper, we propose a long short term memory (LSTM) prefetcher—a neural network based hardware prefetcher to achieve high prefetch accuracy and cover-age while improving prefetch timeliness. The proposed LSTM prefetcher achieves higher accuracy and coverage by training neural networks to predict long memory access patterns.

WebJan 22, 2024 · The first is the traditional data cache prefetcher that recognizes contiguous streams of either ascending or descending cache line accesses. It can be disabled by setting bit 13 of MSRC001_1022 to "1". The other hardware prefetcher is the "memory controller prefetcher". This is a somewhat more general prefetcher, but only operates … WebHardware data prefetcher. The Cortex-A55 core has a data prefetch mechanism that looks for cache line fetches with regular patterns. If the data prefetcher detects a pattern, then it signals to the memory system that memory accesses from a specified address are likely to occur soon. The memory system responds by starting new linefills to fetch ...
