摘要
提出了一种新型的分布式千兆以太网并行传输方案。该方案充分利用了FPGA并行处理、灵活性高的特点,在FPGA中用硬件语言实现了4路千兆以太网控制器,并行数据传输速度高达4Gbit/s,能对带宽在200MHz以内的宽带信号进行无失真采样和实时传输。与传统方案相比,该系统具有硬件开销低、可靠性高、小型化、可远程传输等特点。
A new data transfer method based on distributed gigabit Ethernet parallel transmission system is introduced,which takes full advantages of the high flexibility and parallel processing ability of FPGA.A four-way gigabit Ethernet controller is realized in FPGA with a transmission speed of 4 Gbit/s and capable of accurate sampling and real-time transmission of broad-band signal within the bandwidth of 200 MHz.Compared with the traditional methods,the new method boasts features of low hardware resource costs,high reliance,small size and ability of remote control.
