摘　　要：以LabVIEW编程软件为基础,实现LabVIEW FPGA模块与主机进行数据通信,在指定通信速率下保证数据传输的实时性以及连续传输。使用R Series Multifunction RIO on Real-Time PXI项目类型,采用DMA模式与主机建立通信,对数据通信结果进行分析处理,对比不同参数设定下通信程序运行方式的区别与漏洞,并由此对程序进行改进。采用合适的参数设置,与原先设定方式进行比较,结果证明改进的程序满足预期各项通信指标要求。To realize date communication between LabVIEW FPGA module and host computer with specified communication rate, and ensure the real-time data transmission and continuous transmission, the type of R Series Multifunction RIO on Real -Time PXI project was adopted to establish communication with host computer in DMA mode. By analyzing the communication resuhs, the paper compared the difference and bugs of program running mode in different parameters setting. Then improving the program and setting appropriate parameters, and compared with the original program, the results show that the improved program meet the expected communication requirements.
