Design of a real-time CORBA event service customised for the CAN bus
R. Finocchiaro, Stefan Lankes, Andreas Jabs · 2004
Summary form only given. Real-time CORBA and minimum CORBA are the foundations that many so called distributed real-time embedded (DRE) systems are built upon. These specifications describe middleware suitable for connecting different parts of a complex embedded system. Efficient group based communication in such a system can be achieved by using the event service. We focus on the design of such a service complying with the OMG event service standard. It is optimised for the CAN bus, a widely used interconnect, where real-time characteristics are a requirement. A new protocol for the efficient distribution of events in a CAN-based distributed control system is presented, a protocol which is tailored to the CAN bus and produces very low overhead by utilising CAN-specific features.
