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.

Keywords：embedded ; μC/OS-II; Cortex-M3; TCP/IP protocol
