在FPGA中实现嵌入式TCP/IP通信协议栈

研究了嵌入式TCP/IP通信协议栈在Xilinx FPGA上的实现,介绍了其软硬件的系统组成和原理,提出一种实时操作系统上TCP/IP协议栈的高效工作模式,并在Virtex-5FPGA上移植成功。通过建立测试平台进行数据传输测试,证明其具有稳定、高效的通信性能,为嵌入式设备开发提供了新的思路。

Implementation of Embedded TCP/I P Communication Protocol Stack in FPGA

This article analyzes the implementation of embedded TCP/IP communioation protocol stack in Xilinx FPGA and describes the composition and working principle of hardware and software. A kind of high-efficiency operating mode of TCP/IP protocol stack on real- time operating system is proposed and it is transplanted successfully to Virtex-5 FPGA. Data transmission test is completed by establishing test platform. Test results prove that the system has good stability and high-efficient communication performances, so that it provides a new idea for embedded equipment developments.
