.uC / OS ¢ò Under The TCP / IP Protocol Stack And Implementation

With the application and development of computer system in the area of industrial control system, embedded computer system shows its advantage and promising application prospect. According to the actual demands, this paper presents the implement of TCP/IP protocol for uC/OS â…¡ operating system, and indicates the architecture and technique of the implement for embedded system based on 80x86 series. The designing of network card driver and combing correlate protocols are emphasized in this paper.The porting of uC/OS â…¡ aims at 80x86 series platform. The characteristics of embedded system and the actual demands are the two bases when designing TCP/IP protocol. In order to combine the protocol with uC/OS â…¡ operating system, many unnecessary functions are cut out relative to other implement of TCP/IP protocol. The raw API is packged in the syle of Berkeley socket API for the convenience of third-party customer.The testing result shows that the basic functions of TCP/IP protocol can work very well. The stability and transplant are favourable. The project provides technology foundation for industrial engineer to porting the protocol on singlechip platform.
