基于CPCI总线接口的1553B通讯板卡硬件设计实现

1553B Communication Board Based on CPCI Bus Interface

飞机内部时分制指令/响应式多路传输数据总线,即MIL-STD-1553B(简称1553B)是一种集中式的分时串行总线。在我国现行军用数据总线中1553B总线是最为成熟、应用最为广泛的军用数据总线。针对这一现状,阐述了一种基于CPCI总线接口的1553B通讯板卡硬件设计方法,利用主机的CPCI接口,通过该通讯板卡主机可以访问和控制1553B总线上的远端设备,以主控FPGA、CPCI总线接口处理芯片PCI9054、通讯引擎芯片BU-61581为设计核心。板卡具有热插拔特性,数据传输稳定可靠,且该方法可简化软硬件设计流程。

MIL-STD-1553B(1553B)is a kind of centralized time-sharing serial bus.1553B is the most mature and widely used military data bus in China.In view of this situation,this paper describes a hardware design method of 1553B communication board based on the CPCI bus interface.By using the CPCI interface of the host,the host can access and control the remote devices on the 1553B bus.The core of the design is the main control FPGA,CPCI bus interface processing chip PCI9054 and communication engine chip BU-61581.The board has the characteristics of hot plug,the data transmission is stable and reliable,and the method can simplify the software and hardware design process.
