页面置换算法,Page Replacement Algorithms,在使用分页进行内存管理的操作系统中,需要页面替换算法来决定当新页面进入时需要替换哪个页面。 最佳置换算法(OPT) 最佳置换算法(OPT,Optimal):每次选择淘汰的页面将是以后永不使用,或者在最长时间内不再被访问的页面,这样可以保证最低的缺页率。 最佳置换算法可以保证最低的缺...

To maximize performance, modern operating systems employ sophisticated page replacement algorithms that strive to retain the pages that comprise the working sets (Denning, 1968b) for active processes, i.e., the pages that are in active use, in RAM, but some swapping is still inevitable when ...

For example, in the standard library, instead of having to use global functions for all of the generic algorithms in the standard library (such as map, filter, and sort), those generic algorithms are now available as methods on all of the collection types. Testability. With testability, you...
Frantisek Franek 撰写的Memory as a Programming Concept in C and C++讨论了有效使用内存的技术与工具,并给出了在计算机编程中应当引起注意的内存相关错误的角色。 Richard Jones 和 Rafael Lins 合著的Garbage Collection: Algorithms for Automatic Dynamic Memory Management描述了当前使用的最常见的垃圾收集算法。

若使用部分VPN进行set索引,则可能导致同一个PA映射到两个不同cache set上。需要使用page coloring解决。 4.3 TLB Replacement Policies TLB替换策略与cache替换和Page替换策略略有不同,通常L1 TLB时序较紧张,无法实现复杂的LRU,可用随机替换代替。L2 TLB可实现更复杂的替换机制。
