摘　　要：设计和实现了一种中间件软件,用于连接基于多播机制的雷达扫描单元和基于单播机制的显示单元,并利用DM3730中ARM与DSP双核协作机制,将雷达坐标转换算法的实现交给DSP核处理,解决了单核ARM处理器在数据处理方面性能的不足(丢包问题)。通过实测表明,加入该中间件以后,不仅保障了雷达扫描单元和显示单元的正常通信,提高了显示单元的可移植性,而且优化了系统的显示性能,满足了嵌入式系统的性能要求。This paper designs and implements a middleware software, to shield the different of interface between radar scanning unit based on multicast mechanism and display unit based on unicast mechanism, and by using the cooperation mechanism of ARM and DSP dual-core in DM3730, puts the implement of radar coordinate conversion algorithm processing to DSP core to solve the problem that single-core ARM processor performance does not meet the requirements of data processing speed （packet loss） . Tests show that after joining the middleware, it can not only guarantee normal communication between radar scanning unit and the display unit, improve portability of the display unit, but also optimize the display performance of the system to meet the perfor- mance requirements of embedded systems.
