It introduces the data transfer and structure of ARINC659 that is a proven standard within an Integrated Modular Avionics (IMA) cabinet for commercial transport Aircraft. In order to provide data source for system. It presents the real -time monitoring and recording method accord to ARINC659 protocol based on Verilog HDL. The monitor samples and decodes data and transforms the serial data to parallel, produces the corresponding descriptor word* and communicates with the host through the interface unit based on Xilinx PCI Log-iCore. The results of the experiment indicates that the monitor can analyse · Diagnose and store all the bus messages then submit the data and status word to host with the speed through the PCI interface.%ARINC659是一种具有高数据吞吐量、高故障容错和数据确定性的航空总线;为给系统分析提供数据源,根据ARINC659航空总线表驱动的协议特性,介绍了一种基于Verilog HDL硬件描述语言的ARINC659总线监控器的实现方案,完成了总线的采样,解码,串并转换和存储,并通过状态跟踪方法生成了附有表指令地址和全分辨率时间的描述符；存储的总线数据和生成的描述符通过Xilinx PCI LogiCORE的接口上传给主机;实验结果表明该监控器能实时检测分析ARINC659总线的数据与各种同步信息,实现了PCI 32bit ×33MHz的主控方式数据上传.
