摘要
船舶雷达数据处理设备是许多科研院所面对庞大的雷达数据而研发的处理设备。此类处理设备属于船用设备,且设备中处理板卡众多。为了在不打开设备的情况下,脱离专用的USB-JTAG下载电缆对处理板中的FPGA进行远端升级,本文提出一种虚拟线缆协议,通过以太网,利用Zedboard平台的PS端控制PL端生成的JTAG接口对其进行远程更新与调试的方法。该方案成本较低,易于拓展,同时也提高了更新可靠性。
The ship radar data processing equipment is developed by many scientific research institutes in the face of huge radar data.This kind of processing equipment belongs to marine equioment,and there are many processing boards in the equipment.This study aims to design and implement remote updating and debugging multi-field programmable gate array for the detector without opening the equipment,separate from the specila USB-JTAG download cable.In the paper,a network based Zedboard's processing system is used to accept configuration files via network and generate JTAG by Zedboard's programmable logic sequence to FPGA by means of Xilinx visual cable protocol.The remote updating and debugging of multi-FPGA are realized.This method improves the reliability of remote updating and debugging of FPGAs and is easy to extend with low cost.
