A general LXI bus module based on ARM is presented in this paper and can be employed for multi-frequency HF ground wave radar（HF GWR）.Taking AT91RM9200,DM9161,IDT7028 as basic hardware and Linux as operating system,the reliability of system can be kept by kernel synchronization mechanisms.And this design,which meets the requirements of HF WGR,adopts full-duplex mode and bidirectional interrupts to exchanges a large amount of data in packets,and presents an effective method to measure the whole system.The measurement results show that this LXI bus module can keep efficient and steady,and the average data transfer speed is about 45Mb/s.It meets the needs of HF GWR measurement. 多频高频地波雷达 LXI总线 LINUX 嵌入式系统 multi-frequency HF ground wave radar LXI bus LINUX embedded system TN958;TP311.52 国家高技术研究发展计划（863）资助项目（2006AA09A303） 2008-03-01 2021-04-01 3
