WebbWe consider hardware-only prefetching in this study. Prefetching can be done at any cache level. Level-1 (L1) and level-2 (L2) prefetching lead to different possibilities and tradeoffs, hence different sorts of prefetchers. An L1 prefet-cher can use some informations that it would be somewhat costly to propagate to the L2 cache, such as load ... 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.

Prefetching can be ei-ther hardware-based or software-directed or a combination of both.
