In networked and distributed environments, and in multi-tasking systems, processes run simultaneously and compete to access the system resources. Processes commonly communicate with one another. Various techniques have been adapted in designing Interprocess Communication mechanisms within operating systems such as signals and message-passing. Signals are software interrupts notifying a process that an event has occurred; they do not support data exchange between processes. Message-Passing, a widely used technique in this design, it may use pipes to allow two or more processes to exchange data. Current techniques degrade performance of Real-time Systems, where unmet time critical missions may result in catastrophic failure. This research introduces a library-based architecture for Interprocess Communication Systems (IPC). This technique supports real-time performance and can be adapted for embedded operating systems. Improved Real-time performance was achieved by running IPC as a set of library function and verified by testing on real-time embedded system.
