摘要:

基于LXI总线的1553B及ARINC429通信模块的开发需求,提出了系统软、硬件设计方案;硬件设计使用SOPC Builder将IP核、接口、微处理器等集成到FPGA芯片上,设计了模块的以太网接口、1553B接口和ARINC429接口;构建了系统软件结构,编写了驱动程序,实现了基于μC/OSⅡ和LwIP协议的TCP/IP协议,从而实现了1553B及ARINC429总线的通信协议;最终实现了LXI总线的1553B及ARINC429通信模块。

Abstract:

Aimed at the development requirement of the 1553B and ARINC429 communication module based on LXI bus, the software and hardware of the system is designed. The IP core, the ports and the microprocessor are integrated on the FPGA by using the SOPC Builder. Then the port of the Ethernet, 1553B and ARINC429 is designed. The framework of the system software is built and the drivers are programmed. The TCP/IP protocol based on the μC/OSⅡ and the LwIP is analyzed and achieved. And then the 1553B and ARINC429 bus protocol is completed. At last the 1553B and ARINC 429 communication module of the LXI bus is accomplished.
