摘　　要：国内SOC芯片日益崛起,而国产SOC平台的应用尚未普及。ARM+FPGA架构中,CPU与FPGA通过AXI总线协议进行数据交流,小批量的数据可以通过AXI_lite进行交互,对于大容量的数据需要采用AXI_stream协议。本文进行了复旦微FMQL系列芯片AXI_DMA的应用研究与测试,并与赛灵思ZYNQ_7000系列进行了传输性能对比。Domestic SOC chips are rising day by day,but the application of domestic SOC platforms has not been popularized.In the ARM+FPGA architecture,the CPU and FPGA exchange data through the AXI bus protocol.Small batches of data can interact through AXI_lite.For large-capacity data,the AXI_stream protocol is required.In this paper,the application research and test of Fudan Micro FMQL series chip AXI_DMA is carried out,and the transmission performance is compared with Xilinx ZYNQ_7000 series.
