Design of Remote Terminal in 1553B Bus System Connected with LEON3 SoC

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.
