uIP协议栈在SOPC系统中的应用

为了提高嵌入式系统设计的灵活性,适应未来嵌入式系统发展的方向,提出了一个基于Xilinx FPGA利用片上可编程系统(system on a programmable chip,SOPC)技术实现以太网数据传输的方法.对整个系统的硬件结构,Xilinx SOPC设计所使用的工具、流程和采用的关键技术进行了介绍.在此基础上应用Xilinx的嵌入式开发套件,以Xilinx公司提供的知识产权(intellectual property,IP)核为基础,搭建了一个SOPC平台.将uIP协议栈应用于软件设计中,实现了驱动程序和应用程序的开发.与上位机进行通信测试的结果表明了该设计的可行性和有效性.

Application of uIP stack in SOPC system

In order to improve the flexibility of embedded system and adapt to the future direction of the embedded system development,a method of network data transmission based on Xilinx FPGA and applied the technology of SOPC(system on a programmable chip,SOPC) is put forward.Firstly,the hardware structure of the whole system,the tools,the flows and key technologies is introduced.On this basis,by using EDK(embedded development kit,EDK) tools,a SOPC composed platform by Xilinx IP core is constructed.Then,with the uIP stack in the design of software,the development of drivers and applications are implemented.At last,the design is tested by communicating with the computer to verify its feasibility and validity.
