WebbHardware-based prefetching schemes have two main advantages over software-based schemes: (1) they have better dynamic information, and therefore can recognize things such as unexpected cache conflicts that are difficult to predict in the compiler, and (2) they do not add any instruction overhead to issue prefetches.
