【摘要】 本文对四种总线结构——单总线、全连接多总线、分组连接多总线和BIB结构多总线系统进行了可靠性研究。给出了它们的可靠度表达式,分析了可靠度变化规律,比较了四种总线结构系统的可靠性以及各自的特点,提出了在不同设计要求下,选择系统结构的建议。从系统可靠性设计方面,讨论了总线、处理机和公共存储器配置的关系式。更多还原

【Abstract】 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.更多还原
