摘　　要：移动互联网时代嵌入式处理器得到了快速发展与广泛应用。由于主流嵌入式处理器区别于传统X86架构处理器,需要对操作系统和应用软件进行移植。文中总结了CISC与RISC体系结构的X86、ARM、MIPS等主流处理器体系架构;介绍了我国龙芯处理器体系架构与各型号的发展现状及特点;对Linux操作系统跨处理器体系架构的移植原理进行了初步研究,介绍了交叉编译概念和原理,交叉编译工具集gcc编译器、binutils连接器、glibc运行库的创建原理,交叉编译工具CLFS,本地编译的两种方式。The embedded processor has developed rapidly and applied widely in mobile Internet times. The operating systems and software applications need to be transplanted because the mainstream embedded processor is different from traditional X86 processors. Not only the mainstream processor architecture based on the CISC and RISC,such as X86,ARM,MIPS,but also the development status and characteristics of the domestic Loongson processor architecture and each models are summarized in this paper. Meanwhile,the concept and principle of cross-compiling,the creation principle of cross-compiler toolsets which include gcc compiler,binutils connector and glibc runtime,cross-compiler tool CLFS,two ways of native compilation are also introduced after the principle of transplantation of Linux operating system which is cross-architecture is studied preliminarily.
