WebJun 22, 2024 · Temporal prefetchers have the potential to prefetch arbitrary memory access patterns, but they require large amounts of metadata that must typically be stored in DRAM. In 2013, the Irregular Stream Buffer (ISB), showed how this metadata could be cached on chip and managed implicitly by synchronizing its contents with that of the TLB. WebSep 1, 2024 · Data prefetching, i.e., the act of predicting application's future memory accesses and fetching those that are not in the on-chip caches, is a well-known and widely-used approach to hide the long latency of memory accesses. The fruitfulness of data prefetching is evident to both industry and academy: nowadays, almost every high …
