A five-terminal data bus operating at 1 Mbps was built, tested and evaluated using state-of-the-art fiber optic components. The data bus utilized a modified MIL-STD-1553B protocol and was operated with a central controller and also a distributed bus control algorithm. Problems associated with the USMC Command-Control data bus were identified. (Author)

Markovian models are developed for the performance analysis of multiprocessor systems intercommunicating via a set of busses. The performance index is the average number of active processors, called processing power. From processing power a variety of other performance measures can be derived as dictated by the specific processor application. Exact models are first introduced, and are illustrated with a simple example. The computational complexity of the exact models is shown to increase very...
