linux
- 设计一个简单的文件系统,包含格式化、显示文件(目录)、创建文件、登录等几个简单命令的实现,而且能完成超级块的读写、节点的读写等过程。编写一个基本体现文件系统理论的程序。在节点的使用上,主要模仿Linux的EXT2文件系统。、-Design a simple file system, including format, display file (directory), create a file, registry, such as the realization of a few simple
alloc
- Memory Allocation in C-write part of a dynamic storage allocation package. The package provides three function calls: void initalloc(), to initialize the data structures involved char* alloc(int n), which returns a pointer to a block
Linux_block_driver_write_PPT
- 《Linux块设备驱动开发PPT》。对PPT的封装,介绍了Linux下开发块设备驱动的方法。-write block driver in linux, it s a PPT format
blktrace-1.0.0.tar
- Blktrace是linux系统下用来记录磁盘io读写请求的工具。它由两部分组成:一部分工作在内核态,现在已经是标准内核的一部分,它工作在块设备层;另一部分是用户态程序,由用户输入命令启动。-Blktrace is used to record under the linux system to read and write disk io request tool. It consists of two parts: the core part of state, is now a stand
S-DES
- 1996年, E.Schaefer 提出了一个简化的DES加密算法, 即S-DES加密算法。S-DES是一个对称分组加密的简化模型,目的不在于应用,它非常具体地说明了分组密码中如何实施扩散和扰乱, 揭示了设计分组密码算法的基本模式和框架,在密码学习中有着重要的意义。编写一个软件能够实现S-DES分组加解密-In 1996, E. Schaefer proposed a simplified DES encryption algorithm, namely, S-DES encryption al
1
- 从内存BLOCK开始,存放着256个字节的带符号数。编写程序,找出绝对值最大的数,将其存入MAX中-BLOCK starting from memory, placing a 256-byte signed number. Write a program to identify the largest absolute number of its deposit MAX
u-boot-flash-remove
- FLASH的编程原理都是只能将1写为0,而不能将0写为1.所以在FLASH编程之前,必须将对应的块擦除,而擦除的过程就是把所有位都写为1的过程,块内的所有字节变为0Xff。 对FALSH进行的最基本操作由读操作,写操作,和擦除操作。以下将详细介绍,所有的都是参考sst39vf1601 datasheet -FLASH programming principles are the only one written as 0, can not be written as one. Befo
a-block-driver
- 我们通过写一个建立在内存中的块设备驱动,来学习linux内核和相关设备驱动知识。最简单的方法写出一个能用的块设备驱动。-We write a block device driver, built in memory to learn the knowledge of the Linux kernel and device driver. The easiest way to write a usable block device driver.
blk-core
- This handles all read/write requests to block devices driver for Linux.
bitmaps
- routines to read, write, and manipulate the inode and block bitmaps.
rw_bitmaps
- routines to read and write the inode and block bitmaps.
osjincheng
- 用高级语言编写和调试一个进程调度程序,以加深对进程的概念及进程调度算法的解. 进程调度时进程管理的主要内容之一,通过设计,编制,调试一个简单的进程调度模拟系统,对进程调度,进程运行状态变换加深理解和掌握。模拟计算机操作系统的进程调度,建立进程控制块PCB,要包含有关进程的描述信息,控制信息以及资源信息.模拟系统根据PCB感知进程的存在和通过PCB中所包含的各项变量的变化,掌握进程所处的状态以达到控制进程活动的目的.要实现进程的状态及其转换,进程的创建与撤消,进程的阻塞与唤醒.用P,V原语操

COMbegining
- COM的发展概述 公元一九九五年某个夜黑风高的晚上,我的一位老师跟我说:“小杨呀,以后写程序就和搭积木一样啦。你赶快学习一些OLE的技术吧......”,当时我心里就寻思 :“开什么玩笑?搭积木方式写程序?再过100年吧......”,但作为一名听话的好学生,我开始在书店里“踅摸”(注1)有关OLE的书籍(注2)。功夫不负有心人,终于买到了我的第一本COM书《OLE2 高级编程技术》,这本800多页的大布头花费了我1/5的月工资呀......于是开始日夜耕读..... -COM develo
