Construction of 1553B Bus Based on FPGA and Its Application

A state control and data transform system was developed in FPGA based on 1553B data communication protocol between the command center and a remote terminal. In this system, two FPGA controlled 1553B Bus Protocol chips HI-6110 were configured as Bus Controller (BC) and Remote terminal (RT), respectively. FPGA drives BC to control BT by reading/writing Command and Status Register, and RT transfer data to BC by writing FIFO. Then message communication between BC and RT is achieved. The experimental results show that this method is practical. Moreover, this system can be extended to several RTs controlled by one BC to realize communication between command center and sub-devices in complex applications.
