摘　　要：基于NIOSⅡ处理器搭建了可编程片上系统,在该系统上通过FPGA实现了多通道ARINC429总线协议。NIOSⅡ处理器通过FIFO实现了与USB总线的通信,通过双口RAM实现了与PCI总线的通信。重点论述了NIOSⅡ处理器系统的硬件和软件设计,双口RAM的地址空间划分。经测试验证了用本方法设计的接口卡能很好地实现多通道ARINC429总线协议。The design of System On Programmable Chip （SOPC） based on NIOSⅡ processor is described. By SOPC, multi-channel ARINCA29 bus protocol is implemented by FPGA. NIOSⅡ processor communicates with the USB bus through FIFO, and communicates with the PCI bus through DPRAM. This paper mainly presents the hardware and software design of NIOSⅡ processor system, address space partition of DPRAM, and design of driver. The results of test showed that this bus card can satisfy multi-channel ARINC429 bus protocol.
