Abstract
Fault-tolerant synchronization of real-time equipment connected to a computer network of several tens of meters with an option of including or not including such equipment in the synchronization device is disclosed. Global scheduling of the real-time computer platform in the form of minor and major cycles is provided in order to reduce latency during sensor acquisition. The associated calculation and preparation of output to the actuator is provided in an integrated modular avionic (IMA) architecture. To achieve the foregoing, a synchronization bus separate from the data transfer network and circuits interfacing with this specific bus for processing the local real-time clocks in each piece of equipment in a fault-tolerant, decentralized manner is provided.
