Note: the CPU knows your virtual address spaces and a whole lot more. So "looking like a pointer" is not just a 64 bit hexadecimal value, but the CPU has the possibility of checking whether it's a sane virtual address and other heuristics. Also, if you make an incorrect prefetch decision, it's not a big deal. Just one wasted cache line. |
