【摘要】：针对传统数据采集传输系统普遍存在的传输速率低、硬件无法升级、实时性和通用性不足等问题,文中提出了一种基于FPGA的以太网高速数据传输方案。该方案采用集成在FPGA内部的Nios II作为控制单元,通过移植操作系统和精简TCP/IP协议栈并编写上层应用程序,控制外部千兆以太网PHY芯片实现了数据的高速传输。通过在搭建的实验平台上进行多串口数据采集传输测试,验证了该系统运行稳定、传输速率高、误码率低,同时,该系统也具备了可编程、可裁剪和易扩展的优点。
[Abstract]:Aiming at the problems such as low transmission rate, inability to upgrade hardware, lack of real-time and generality in traditional data acquisition and transmission system, a high-speed data transmission scheme based on FPGA Ethernet is proposed in this paper. The Nios II integrated in FPGA is used as the control unit in this scheme. By transplanting the operating system, reducing the TCP/IP protocol stack and writing the upper application program, the external gigabit Ethernet PHY chip is controlled to transmit data at high speed. It is proved that the system has the advantages of stable operation, high transmission rate and low bit error rate. At the same time, the system also has the advantages of programmable, clippable and extensible.
