众所周知，翻译LookAside缓冲液（TLB）对系统性能的重要性。有大量有关用于缓存的文献的文献，尚不清楚如何对TLB进行调整（或者是否有不同的问题），它们适合TLB预取的适合状态，以及如何与他们与新近预取相比机制。本文介绍了不同预摘要机制（先前建议用于缓存）的第一个详细比较 - 任意步幅预取triceing和Markov预取的TLB条目，并评估其优点和缺点。此外，本文提出了一种新型的预取机制，称为距离预取的，该机制试图捕获比以前的提议较小的空间中参考行为中的模式。本文使用不同基准套件和所有规格CPU2000应用程序的各种应用程序（共56个）的详细模拟，展示了距离预取的好处。
The importance of the translation lookaside buffer (TLB) on system performance is well known. There is a large body of literature on prefetching for caches, and it is not clear how they can be adapted (or if the issues are different) for TLBs, how well suited they are for TLB prefetching, and how they compare with the recency prefetching mechanism. This paper presents the first detailed comparison of different prefetching mechanisms (previously proposed for caches) - arbitrary stride prefetching and Markov prefetching -for TLB entries, and evaluates their pros and cons. In addition, this paper proposes a novel prefetching mechanism, called distance prefetching, that attempts to capture patterns in the reference behavior in a smaller space than earlier proposals. Using detailed simulations of a wide variety of applications (56 in all) from different benchmark suites and all the, SPEC CPU2000 applications, this paper demonstrates the benefits of distance prefetching.
