LAVI 1553 B communication system

The avionics in the LAVI aircraft is comprised of about 20 embedded computer subsystems interconnected by means of a MIL-STD-1553 B communication network. This network, consisting of two dual redundant communication channels, handles approximately 300 messages, part of which are periodic and part of which are randomly generated. In addition, many messages cannot tolerate long delay times. The authors present the protocol of the communication system, its hardware/software structures that free the HOST processor from communication overhead, and describe the set of software tools used to develop and maintain the communication system and to monitor its performance.<
