摘要
Linux是一套免费使用和自由传播的类Unix操作系统,是一个基于POSIX和UNIX的多用户、多任务、支持多线程和多CPU的操作系统。它能运行主要的UNIX工具软件、应用程序和网络协议。它支持32位和64位硬件。Linux继承了Unix以网络为核心的设计思想,是一个性能稳定的多用户网络操作系统。内核是操作系统的核心,具有很多最基本功能,它负责管理系统的进程、内存、设备驱动程序、文件和网络系统,决定着系统的性能和稳定性。笔者选取飞思卡尔公司生产的基于ARM926EJ-S内核的i.MX28处理器作为ARM平台,对Linux操作系统进行相关开发,并移植到该ARM平台上去,主要内容包括U-Boot的开发、内核开发和移植、文件系统的制作与移植以及系统集成测试。
Linux is a free-to-use and freely distributed Unix-like operating system.It is a multi-user,multi-tasking,multithreaded and multi-CPU based operating system based on POSIX and UNIX.It runs major UNIX utilities,applications and network protocols.It supports both 32-bit and 64-bit hardware.Linux inherits Unix’s network-centric design philosophy and is a stable multi-user network operating system.The kernel is the core of the operating system and has many of the most basic functions.It is responsible for managing the system’s processes,memory,device drivers,files,and network systems,which determine the performance and stability of the system.The author selects the i.MX28 processor based on ARM926 EJ-S kernel produced by Freescale as the ARM platform,and develops the Linux operating system and transplants it to the ARM platform.The main contents include U-Boot development and kernel development.And porting,file system production and porting,and system integration testing.
