摘　　要：TMS320DM642平台上实现TCP/IP通信,可为嵌入式多媒体系统的网络应用提供技术支持。分析TMS320DM642芯片功能和轻量级网络协议(LWIP)层次结构,通过LWIP的移植,实现TMS320DM642非网络开发者套件(NDK)解决方案的TCP/IP网络通信,实例验证了LWIP移植方法的有效性。The implementation of TCP/IP protocol stack on TM320DM642 platform could provide technological support for the application of multimedia embedded systems to networks. Both the function of TM320DM642 chip and the hierarchical structure of Light Weight Internet Protocol（LWIP） were analyzed. Network communications for TM320DM642 systems were implemented by the transplantation of LWIP, not by a solution scheme of Network Developer＇s Kit（NDK）. Testing examples verified the effectiveness of the LWIP transplantation method.

关 键 词：TMS320DM642平台 轻量级网络协议 TCP/IP协议栈
