[OS DevelopLinux内存管理模拟器

Description: Linux下使用c语言实现的内存管理模拟器 假设有台计算机物理内存大小为4MB,每个内存页大小为4k。采用分页机制,使用二级页表,第一级为页目录,共有1024项,每个页目录项指向一个页表,每个页表项指向一个实际的物理页面,每个页表共有1024个页表项。假设页目录和页表不占用内存空间。 系统中还有一个交换设备,采用分块管理机制,每块大小为4K,共1024个。有一系列内存访问指令,系统根据内存访问指令的内存虚地址访问内存。如果页目录项为空,则分配一个页表,并将相关值存入页目录项,如果页表项为空,则请求分配一个内存页,如果没有空闲内存,则使用页面置换算法换出一个内存页到交换设备上。如果页表项表明内存页在交换设备上,则先请求一个物理内存页,然后从交换设备上读入内存内容,释放交换设备上的磁盘块。-use Linux c language memory management simulator assumptions computers to the physical memory size 4 MB, each memory page size to 4k.

[Embeded Linuxwar

Description: 压缩解压算法LZ77算法有许多派生算法(这里面包括 LZSS算法)。它们的算法原理上基本都相同,无论是哪种派生算法,LZ77算法总会包含一个动态窗口(Sliding Window)和一个预读缓冲器(Read Ahead Buffer)。动态窗口是个历史缓冲器,它被用来存放输入流的前n个字节的有关信息。一个动态窗口的数据范围可以从 0K 到 64K,而LZSS算法使用了一个4K的动态窗口。预读缓冲器是与动态窗口相对应的,它被用来存放输入流的前n个字节,预读缓冲器的大小通常在0 – 258 之间。这个算法就是基于这些建立的。用下n个字节填充预读缓存器(这里的n是预读缓存器的大小)。在动态窗口中寻找与预读缓冲器中的最匹配的数据,如果匹配的数据长度大于最小匹配长度 (通常取决于编码器,以及动态窗口的大小,比如一个4K的动态窗口,它的最小匹配长度就是2),那么就输出一对〈长度(length),距离(distance)〉数组。长度(length)是匹配的数据长度,而距离(distance)说明了在输入流中向后多少字节这个匹配数据可以被找到。-err
