This thesis describes the detailed design of a distributed operating system for a real-time, microcomputer based multiprocessor system. Process structuring and segmented address spaces comprise the central concepts around which this system is built. The system particularly supports applications where processing is partitioned into a set of multiple processes. One such area is that of digital signal processing for which this system has been specifically developed. The operating system is hierarchically structured to logically distribute its functions in each process. This and loop-free properties of the design allow for the physical distribution of system code and data amongst the microcomputers. In a multiprocessor configuration, this physical distribution minimizes system bus contention and lays the foundation for dynamic reconfiguration. (Author)
