WebbPrefetching, in both hardware and software, is among our most important available techniques for doing so; yet, we claim that prefetching is perhaps also the least well-understood.

WebbOther types of prefetchers interact with hardware struc-tures [6], [26], [30], [31], [38], such as the branch predictor (e.g. BTB directed), to gain insights into the program’s exe-cution ahead of time, however they require intrusive changes in the processor design. Typically, prior work in prefetching has adopted look-ahead WebbHardware Data stored in general reg-isters If the traversal decisions depend on some external value stored outside the data structure (e.g., a value being searched), this could provide a useful breakdown between traversal paths.
