基于TQ2440平台的嵌入式LwIP协议栈的移植与实现

Transplant and Implementation of Embedded Lw IP Protocol Based on TQ2440 Platform

Lw IP是一种轻量级的开源TCP/IP协议栈,具有移植性强、资源占用率低等优点,适用于嵌入式系统中。分析嵌入式系统中TCP/IP协议栈的特点和TCP/IP协议栈的工作原理,重点讲述TQ2440平台下的网络驱动设计过程,介绍将Lw IP移植到TQ2440平台的过程和方法,通过实验测试证明移植方法的正确性。

Lw IP is a light weight open source TCP/IP protocol with good transplant and low capacity which is suitable for embedded system. Analyzes the characteristics and principles of TCP/IP protocol stacks in embedded system, introduces the processes and methods for transplanting Lw IP to TQ2440 platform, and prominently describes the design of network driving under the TQ2440 platform, tests and improves the correctness of the transplant.
