A bus is always a bus – but there are ‘buses’ and ‘buses’!
In fact, from one bus to the next, the problems to be solved remain the same, but the different characteristics of the proposed fields of application modify the hierarchical order of the parameters to be considered, and result in the development of new concepts in order to find neat solutions to the difficulties encountered. Here is a quick list of the virtually unchanging problems encountered in bus and network applications:
‘Distributed’ real-time control systems, based on an operating system located within a single processor, interconnected by a communication network with distributed processors, are currently providing a significant addition to ‘parallel’ systems.
In addition to the simple exchange of data, the processing must be synchronized, in other words, the execution must follow certain interrelated logical sequences. In these systems, the messages ...
