INTRODUCTION Hardware prefetching is an important feature of modern high-performance processors. When the application working set is too large to fit in on-chip caches, disabling hardware prefetchers may result in severe performance loss. Hardware prefetchers try to exploit certain patterns in ap-

Prefetching can be ei-ther hardware-based or software-directed or a combination of both. Hardware-based prefetching, requiring some sup-port unit connected to the cache, can dynamically han-
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.
