Well, I think hardware and software prefetch, speculation is a special form of prefetch, might be revisited. Software prefetch was at best a hopeful technology even in 2007 and is widely avoided today. https://yarchive.net/comp/linux/software_prefetching.html https://yarchive.net/comp/linux/software_prefetching.html Something I don't think either Drepper or Hennessy + Patterson's books get across is memory banks from a programmer's perspective. How cache organization affects a program is explained well but how banks affect said same isn't. Construction yes. Visibility, no.
