摘　　要：分析了由8位和16位MCU组成的嵌入式系统的特点,研究了嵌入式系统中TCP/IP协议栈的体系结构,提出了嵌入式系统中TCP/IP协议选择的方法和功能裁剪的策略,阐述了嵌入式系统实现TCP/IP协议过程中需要解决的关键问题,给出了协议处理的总流程.在对各协议控制字段进行深入分析的基础上,从编程和应用的角度给出了具体的解决方案和实现方法.实验表明,方案和方法对嵌入式Internet系统设计具有一定的参考价值.The characteristics of embedded systems based on 8-bit or 16-bit MCU are analysed. The system framework of TCP/IP protocol stack for embedded systems is researched. A method to choose TCP/IP protocols and a strategy to cut out functions are presented. For implementing TCP/IP protocols in an embedded system, the key problems need to be solved and the flow chart for protocol processing are described. Based on an in-depth analysis of control field for protocols, from the points of program and applications, the detailed solution schemes and implementation techniques are given. The experimental results show that the scheme and techniques have some reference value for the design of embedded internet systems.
