Prefetching

Prefetching in computer science is a technique for speeding up fetch operations by beginning a fetch operation whose result is expected to be needed soon. Usually this is before it is known to be needed, so there is a risk of wasting time by prefetching data that will not be used. The technique can be applied in several circumstances:

  • Cache prefetching, a speedup technique used by computer processors where instructions or data are fetched before they are needed
  • Prefetch input queue (PIQ), in computer architecture, pre-loading machine code from memory
  • Link prefetching, a web mechanism for prefetching links
  • Prefetcher technology in modern releases of Microsoft Windows
  • Prefetch instructions, for example provided by
    • PREFETCH, an X86 instruction in computing
  • Prefetch buffer, a feature of DDR SDRAM memory
  • Swap prefetch, in computer operating systems, anticipatory paging
