REAL - TIME EMBEDDED SYSTElkS \ \ message scheduling controller area network
The Controller Area Network has a maximum transmission rate of 1 Mbitk and its fixed priorities-based medium access control limits the maximum bus utilisation when timeliness guarantees are required. An implementation of earliest deadline first (EDF) message scheduling on CAN, based on the F’IT CAN protocol, is presented, which allows higher utilisation factors with timeliness guarantees. The a...

متن کاملReal-Time Communication Support for Embedded Linux over Ethernet
Many embedded systems are exploiting embedded Linux due to its rich features and device drivers. However, since embedded Linux is inherited from traditional monolithic kernel design, it has limitations to support real-time communication. One such example is that the protocol stacks of embedded Linux are following the bottom half based architecture. The user-level operations of a higher priority...
متن کاملScheduling hard and soft real-time communication in a controller area network
The paper introduces a mechanism to implement distributed scheduling for the CAN-bus resource in order to meet the requirements of a dynamic distributed real-time system. The key issues considered here are multicasting, distinguishing between hard real-time, soft real-time, and non-real-time constraints, achieving high resource utilization for the CAN-bus, and supporting dynamic hard real-time ...
