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.
