摘　　要：针对流星突发通信中实时高速数据传输的系统需求,采用ARM核芯片AT91RM9200作为核心微控制器,TMS320C6713B作为数字信号处理器,提出了基于ARM与DSP之间同步串行通信接口的系统实现方案,并给出了系统的硬件原理图、控制方法及基于Linux的主要硬件接口驱动程序设计。硬件测试结果表明,该系统通过中断方式可以实时高速的接收由DSP发送到ARM的数据,实现流星余迹通信的实时信号处理和数据传输。According to the real-time and high-speed data transmission demand of the burst communication, the AT91RM9200 chip based on ARM core is adopted as the chief microprocessor, and TMS320C6713B is also employed as digital signal processor to realize the the synchronous serial communication between ARM and DSP. The schematic digram of hardware, the control method and the driver of the chief hardware interface on Linux are prersented. The results of hardware tests show that the system can receive data from DSP to ARM with high-speed by interrupt mode, and realize the real-time signal processing and data transmission for meteor burst communication.
