文章根据“九五”国家重点攻关项目“重大自然灾害监测系统”机载雷达图像实时传输子系统中原“八五”系统用户的要求,详细讨论了地面数据接收站数据处理单元与高速图形处理工作站之间的数据传输接口板的设计原理、方案及其实际应用。提出的以同步传输的方式工作具有特殊的新颖性,可以提高传输速率近一倍,并且该接口板特征地址可灵活配置,同时还具备单机调试功能,在实际中取得了较好的效果。
According to the requirements of users of the “Eighth Five-Year Plan” system in the central airborne radar image real-time transmission subsystem of “Major Natural Disaster Monitoring System”, a national key project of the Ninth Five-Year Plan, this paper discusses in detail the relationship between the data processing unit of the ground data receiving station and the high speed graphics processing workstation Data transmission between the interface board design principles, programs and their practical application. The proposed work in synchronous transmission has a special novelty, which can increase the transmission rate almost doubled. Moreover, the interface address can be flexibly configured and has the stand-alone debugging function. In practice, good results have been achieved.
