摘　　要：为了解决传统FPGA数据信号处理系统的缺点,设计了基于Xilinx FPGA XCZU9EG高速信号数据处理系统。该高频信号采集系统将内存与AXI4-Stream外设之间的高宽带数据直接快速迁移至内存中,然后通过AXI-DMA CIE_2.0x4接口将内存数据迁移至带有控制器的固态硬盘中。所有的数据文件统一部署在linux服务器中,支持FTP上传下载和Samba文件共享功能。该系统经过测试,数据整齐有序排列、误码率低、传输速度快,该高速信号数据处理系统具备较高的可行性。In order to solve the shortcomings of traditional FPGA data signal processing system,a high-speed signal data processing system based on Xilinx FPGA xczu9eg was designed.In the new system,the high frequency signal acquisition system directly and quickly migrates the high broadband data between the memory and axi4 stream peripherals to the memory,and then through axi-dma CIE_2.0x4 interface migrates the memory data to the solid-state disk with the controller.All data files are uniformly deployed in the Linux server,which supports FTP upload and download and Samba file sharing functions.After testing,the system was demonstrated to have the advantages of orderly arrangement of data,low bit error rate and fast transmission speed,and therefore have high feasibility.
