A Distributed Real-Time Java System Based on CSP

CSP is a fundamental concept for developing software for distributed real-time systems. The CSP paradigm constitutes a natural addition to Object Orientation and offers higherorder multithreading constructs. The CSP channel concept that has been implemented in Java deals with single- and multi-processor environments and also takes care of the real-time priority scheduling requirements. For this, the notion of priority and scheduling has been carefully examined and as a result it was reasoned that priority scheduling should be attached to the communicating channels rather than to the processes. In association with channels, a priority based parallel construct is developed for composing processes – hiding threads and priority indexing from the user. This approach simplifies the use of priorities for the object-oriented paradigm. Moreover, in the proposed system, the notion of scheduling is no longer connected to the operating system but has become part of the application instead.
