Webb31 dec. 2016 · CPU Hardware Prefetch is a BIOS feature specific to processors based on the Intel NetBurst microarchitecture (e.g. Intel Pentium 4 and Intel Pentium 4 Xeon). These processors have a hardware prefetcher that automatically analyzes the processor’s requirements and prefetches data and instructions from the memory into the Level 2 … Webbmarks, with equally simple hardware. 1. 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-

Part of the gap can even be eliminated with sophisticated programmer- and compiler-directed software-prefetching mechanisms [2, 4, 30, 41]. More ideal is a pure-microarchitecture technique that can do the same: achieving high performance for memory-latency- Webblibraries; (ii) Hardware support for efficient user-transparent persistent reference is crucial. The pure software implemen-tation slows down the original libraries by 2:75 on aver-age, while the hardware support removes nearly the entire performance loss.

The following sec-tion gives some background on these prefetching techniques. 2.1 Hardware vs. Software Prefetching There are two distinct types of prefetching, hardware and software. With software prefetching the compiler or pro- 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.
