基于Ctex-M3的TCP/IP协议栈的设计与实现

摘要近年来，随着电子科技、自动化的发展，嵌入式技术发展迅猛，在人们日常生活的各个领域，如工业控制、办公自动化、电子设备等已经得到了广泛应用。同时，Internet技术也得到了广泛的发展，其与嵌入式设备的连接也日趋紧密，越来越多的嵌入式设备需要连入Internet，相应地，嵌入式Internet技术应运而生，并成为嵌入式技术的一个重要的发展方向，具有重大的经济和研究意义。本文深入分析了嵌入式实时操作系统μC/OS-II的工作原理，并将Cortex-M3内核与ARM7内核进行比较，发现Cortex-M3内核的优势，选用了Luminary公司的基于Cortex-M3内核的LM3S8962芯片，将μC/OS-II移植了过去，在此基础上进行了嵌入式TCP/IP协议栈的研究。59663

Title Design and Implementation of the TCP/IP Protocol Stack Based on Ctext-M3

Abstract

In recent years, with the development of electronic technology and automation, the rapid development of embedded technology in all areas of daily life, such as industrial control, office automation, electronic devices have been widely used. At the same time, Internet technology has also been widely developed. The connection between embedded devices and Internet technology is becoming increasingly closer, more and more embedded devices need to be connected to the Internet. Accordingly, embedded Internet technology come into being, and become an important developing direction of the embedded technology, which is of great economic and researching value. In this paper, working principle of the embedded real-time operating system μC / OS-II is deeply analyzed, and the advantages of the Cortex-M3 core are found after the compare between Cortex-M3 core and ARM7 core. So the LM3S8962 chip from Luminary company, which is based on the Cortex-M3 core, is chosen. μC / OS-II is transplanted, and on that base, the research of the embedded TCP / IP protocol stack is accomplished.
