摘　　要：为了满足多处理器之间实时传送雷达数据及成像结果的需要,构建了以STM32F103VE和TMS320C6747芯片为核心的探地雷达显控单元,采用了基于HPI接口的多处理器间的数据交互技术,并给出了HPI接口的硬件结构、详细配置方法及软件设计流程。结果表明该技术具有电路结构简单,传输速率高,工作稳定可靠等特点,并可适用于其他嵌入式系统。To achieve real-time transmission of radar data and imaging results between multiple processors, a display and control terminal of GPR with STM32F103VE and TMS320C6747 chips as the core is constructed. The data interaction technolo- gy between multiple processors based on HPI interface is adopted, and hardware structure, parameters configuration and soft- ware design procedure related to HPI interface are given in the paper. The results demonstrate that the proposed method has the characteristics of simple circuit structure, high transmission rate, stability and reliability, which is suitable for other embedded systems.
