Research and Design of 1553B Protocol Bus Control Unit

Abstract

In avionics system, the 1553B interface board is an important part in the whole system, and it mainly integrates data in bus, share resources, coordination tasks, and fault-tolerant reconstruction. The technology of compatible with high-performance general-purpose microcomputer and large-scale integrated circuits is widely applied to complete interface communication from the 80s in our country. The Bus Controller Unit (BCU) not only insures sending or receiving commands is correct, but also monitors the bus status. The chapter introduces a new design method based on 1553B protocol in order to design BCU. Based on in-depth study, 1553B bus transport protocols and foreign design method of chip, and combined with popular EDA technology, the chapter has designed successfully the digital 1553B MIL-STD-BCU under the top-down design method, and proved to be correct on self-designed experiment board.
