A polled contention multiplex system using MIL-STD-1553 protocol
Abstract
The polled contention mode in the Avionic Multiplex System is discussed, and a technique to pass the bus controller function between the terminals based on the activity of input data is presented. Improvements such as decreased data latency, more efficient bus utilization, and simplicity in software implementation are reviewed, and associated problems are considered. It is concluded that the use of dynamic bus allocation will have increasing significance as future systems become larger and more complex, while the polled contention mode may be a viable alternative to the command response system.
