摘　　要：通过RT-AHB桥连接1553B总线终端RT与AHB总线,将LEON3SoC接入了1553B总线系统.设计了此连接模型中的远程终端,支持双重冗余总线操作,有设置非法命令字和消息差错位的能力,不使用测试手段位以避免减少可挂载的子系统数目,可输出其运行状态至子系统,提高了远程终端的可靠性和可配置性,且使其易于维护.仿真结果表明,该远程终端能够实现协议规定功能和提出的优化设计.This paper utilizes a RT-AHB bridge to complete the connection between a LEON3 SoC and a remote terminal of the 1553B bus. This paper designs the remote terminal which is one of the two key parts of 1553B bus, it can operate in dual standby redundant bus, set commands illegal from outside and set the message error bit, and it doesn＇t use the instrumentation bit to avoid the number of subsystems decreasing, and its state can be transferred to subsystems. The simulation results show that this remote terminal satisfies the 1553B agreement and its features designed in this paper work well.
