提出了基于C/OS-II的LwIP协议栈在SoPC系统中实现的方案。介绍了嵌入式TCP/IP协议栈LwIP,阐述了其移植原理;在SoPC系统上实现了LwIP协议栈的移植,并给出了在具体软、硬件平台上的移植实例。实验结果表明:移植后的协议栈实现了网络的基本功能,且运行稳定,为SoPC类型的Internet嵌入式系统应用提供了一个基于C/OS-II的小型网络模块。该方案可应用于信息电器和网络化的仪器、仪表方面。
Proposed based on C / OS-II LwIP protocol stack in SoPC system to achieve the program. The embedded TCP / IP protocol stack LwIP is introduced, and its porting principle is expounded. The porting of LwIP protocol stack is implemented on SoPC system, and the porting examples on specific software and hardware platforms are given. The experimental results show that the protocol stack after transplantation has realized the basic functions of the network and has stable operation, and provides a small network module based on C / OS-II for SoPC type Internet embedded system applications. The program can be applied to information appliances and networked instruments, meters.
