Abstract :
UM-BUS aims to provide a consistent quality of service for high-reliability applications. It provides serial, high-speed, half-duplex, bi-directional data links which connect together enabled equipments directly. With N( ≤ 32) concurrent lanes, which construct a mutual redundant structure, the maximum communication rate is 3.2Gbps. The UM-BUS can reconfigure its lanes automatically when fault is detected, in that way the reliability of the system and real-time capability can be significantly improved. The Data Link Layer of UM-BUS is responsible for the automatic reconfiguration of the packet, based on the number of the health physical lanes. If any lane fails, the whole packets can be automatically redistributed to the Physical Layer to be retransmitted through the health lanes and the communication process can be resumed.
