Pagination or Media Count:
MITRE has designed, constructed, and operated an avionics time division multiplex bus compatible with the requirements of MIL-STD-1553 USAF. In the course of engineering the software to perform the message control function for this network, some constraints on the message flow were encountered that are not immediately apparent when reading the standard. The purpose of this report is to alert the system designer to some of these potential difficulties. Four main topics are discussed 1 Bus capacity 2 A time constraint on message handling 3 Subaddresses, and Data Word accessibility and 4 Temporal characteristics of information transferred on the bus.
