摘要
近年来1553B总线在航空航天军事等领域中获得广泛应用。但当前1553B总线设计大部分基于分立的接口芯片,应用复杂且价格昂贵。现SOPC设计思想,提出了在FPGA上实现1553B总线终端接口的设计方案。用VHDL语言进行设计并在Xilinx公司FPGA芯片上验证。文章中对方案的硬件系统设计、存储器结构设计、软件流程都做了相应介绍。
1553B bus is increasingly used in aviation and space flight fields in recent years. The existing designs of 1553B bus are mostly based on the separated interface chips, which are complex and expensive. The design of 1553B Bus＇ Remote Terminal interface based on FPGA is introduced in this paper, which is realized through VHDL on the chip of Xilinx. Hardware system, memory structure and software flow of the design are introduced in the paper.
