"WebNov 11, 2024 · Here it goes. Modern CPUs offer explicit cache prefetching. What this means is that the program can issue a special prefetch instruction, that will go to the main memory, fetch a cache line and load it into the data cache. All this happens in the background while CPU is free to do other things. " - Data prefetching

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. Webdelays, data prefetching is more critical in alleviating penalties from increasing memory latencies and demands on Chip-Multiprocessors (CMPs). Through deep analysis of SPEC2000 applications, we find that a part of the nearby data memory references often exhibit highly-repeated patterns with long, but equal block reuse distance.
