摘　　要：ARINC429是航空电子设备之间数据传输的航空工业标准,文中介绍了ISA总线接口的基于DSP的ARINC429标准通信扩展板的硬件组成原理及软件设计;该扩展板以双端口RAM作为数据交换的载体,在一块板上实现了4发8收的功能,该板经过检验,实可完整真实收发数据,已经在某型直升机半物理仿真实验系统中成功应用。The ARINC429 bus is an aero standard of data transmission between avionics equipment. A detailed introduction about the hardware strueture and software design for the ARINC429 communication extended-board based on DSP is presented. Eight receive than＋ nels and four transmitting channels were built in this board, owing to use dual interface RAM as carrier of data exchange. Now, this board has been eheeked up that can send and receive data fully and truly; then it is used successfully in a helicopeter hardware-in-the-loop simulation system.
