ABSTRACT:
This invention concerns a time-triggered method and a device for the autonomous transmission of messages within a distributed real-time computer architecture, consisting of a plurality of nodes that are connected to a shared communication channel. This method uses either an available standard communication control unit (e.g., UART, CAN, J1850 or others) or an augmented communication control unit. It provides an efficient low-cost communication service, including the clock synchronization. This new method supports composability by an autonomous time-triggered operation of the data transmission system. It is characterized by a predictable timing behavior, a high data efficiency, and a short error detection latency.
