Reliability Analysis and Comparison for Several Types of Bus Systems

The reliability of four types of bus systems: single bus system, completely-connected multibus system, partially connected multibus system and BlB-structured multibus system is analysed. Reliability expressions and their varying laws are given. After comparing the reliability for four types of bus systems, the suggestions to choose adequate bus structure are proposed.Finally,from the reliability design, the optimal relations of bus submodule, processor submodule and memory submodule are discussed.
