摘要
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。
The implementation project of the LwlP stacks based on μC/OS-Ⅱ in SoPC system is proposed. Firstly, the embedded TCP/ IP stacks LwIP is introduced and the porting principle is described in detail. Then, LwIP stacks is ported successfully to the SoPC system with an porting example aiming at the Software-Hardware platform. The experiment shows that the ported stacks realize the fundamental network functions and run stably. A mini-type network module based on μC/OS-Ⅱ is supplied for the SoPC-type Internet applications of embedded systems. The project proposed is applied in information appliance and network equipments.
