基于SOPC的ARINC429总线接口设计

The design of ARINC429 data bus interface based on SOPC

在研究ARINC429总线通信协议的基础上,提出了一种基于SOPC技术的ARINC429总线通用接口的设计方法。将NiosII软核处理器与各种功能模块集成在FPGA内部,外加通信协议芯片HS3282、HS3182,实现了429总线通用接口功能。由于SOPC技术能实现硬件设计软件化,所以该系统结构简单,使用灵活并易于扩展,具有良好的应用价值。

Based on researching the communication protocol of ARINC429, a new ARINC429 data bus interface based on SOPC has been designed. Adding communication protocol chip HS3282 and HS3182, integrating NiosII CPU and other functional modules in FPGA, the requirements of ARINC429 universal interface are satisfied. Adopting SOPC technology, hardware system designing can be replaced by software system designing, so the system has a simple structure with capability and flexibility, and has a nice application value.
