为了满足国家重点专项“量子科学实验卫星”中“量子存储板”高速串行数据传输的测试要求,提出了一种以Nios II嵌入式处理器为控制核心,TLK2711、RS422、USB2.0和千兆以太网为传输接口的高速数据传输解决方案；系统采用TLK2711完成高速数据的串并转换,采用RS422完成命令和控制信号的传输,实现与“量子存储板”的高速数据传输；利用Xilinx公司Zynq-7000芯片独有的ARM+FPGA架构实现千兆以太网完成数据的高速传输,利用EXAR公司XR21V1414 USB转串口芯片实现命令、遥测等数据的传输；采用Labview编写上位机控制整个系统的运行,实现命令发送、指令解析、运行状态显示、数据帧产生、高速数据传输、解析和存储等功能；实测结果表明,此系统数据传输速率高达600 Mbps,满足高速串行数据传输的要求,且具有稳定性高、可靠性好等优点。

Design and Implementation of High-speed Data Transmission Based on FPGA

This paper proposes a new solution to high-speed serial data transmission. Taking the high-speed requirement into consideration, the system takes a Nios II embedded processor as the control core. In addition to, TLK2711 and Gigabit Ethernet are used as the transmission interface. TLK2711 are used to do the high-speed data serial-to-parallel conversion. Gigabit Ethernet which is constructed by the unique ARM+FPGA architecture contained in the Zynq-7000 chip of Xilinx, is taken to complete high-speed data transmission work. The measured results show that the system has the advantages of high stability and reliability, besides the data transmission rate is up to 600Mbps.
