http://en.wikipedia.org/wiki/Page_replacement_algorithm#Least_recently_used 之前在网上看到过网友的一个C++实现,感觉不错,所以核心代码就采用了他的设计。相关链接如下: http://www.cppblog.com/red22/articles/62499.html 原作者通过两个MAP对象来记录缓存数据和LRU队列,注意其中的LRU队列并不是按照常用的方...
Over the years many algorithms have been proposed for page replacement. Each algorithm attempts to minimize the page fault rate while incurring minimum overhead. , In this paper we discuses at the traditional algorithms such as LRU. Least Recently Used (LRU) page replacement algorithm is most ...
数值和_PAGE_DIRTY相同,但用于不同的上下文,即页不在内存中的时候,显然不存在的页不可能是脏的(因为它不可能被进程修改),因此可以重新解释该比特位1) 如果没有设置,则该项指向一个换出页的位置2) 如果该项属于非线性文件映射,则需要设置_PAGE_FILE5. _PAGE_USER 如果设置了_PAGE_USER,则允许用户空间代码访...
Replacement method ETA with least recently used (LRU) algorithm is used. Energy efficient mechanism in cache memory using in ETA method The former is actually the combination of Prob(p) and LRU. The latter is the update version of LRU-PC with a Secondary List (SL). Cache-filter: a cache...
This project implements a simple thread-safe cache with several page replacement policies: Least Recently Used First-In/First-Out Least Frequently Used More about cache algorithms and policy you could read onWikipedia Usage Using this library is simple. It is necessary to include header with the ...
Trap handleris code within the OS that is written with the purpose of handling TLB miss.陷阱处理程序是操作系统中的代码,其目的是为了 处理TLB缺失。 比如MIPS R10k,Sun的SPARC v9…… 💬 TLB Control Flow Algorithm (Software Managed TLB)
This article argues that the self-tuning, low-overhead, scan resistant adaptive replacement cache (ARC) algorithm outperforms the least-recently-used (LRU) algorithm by dynamically responding to changing access patterns and continually balancing between workload recency and frequency features. The ARC'...
Although they outperform the traditional LRU policy in performance, they do not consider the access frequency of clean page, which will consequently result in poor I/O performance. In order to solve this problem, we present a new buffering algorithm in this paper, called CCF-LRU, which ...

Page table is per-process data structure and is kept inmainmemory. 页表是每个进程的数据结构,保存在主内存中。 每个数据/指令访问都需要两次内存访问(一个是页表,一个是数据/指令) The two memory access problem can be solved by the use of a special fast-lookup hardware cacheinside the MMUcalled ...
