A desired mesh architecture, based on connected-cycle modules, it constructed. To enhance the reliability, multiple bus sets and spare nodes are dynamicaly inserted to construct modular blocks. Two econfiguration schemes are associated, and can eliminate the spare subsitution domino effect. Simulations show that both schemes provide for increase in reliability over the interstitial redundance scheme[11] and the multi-level fault tolerance mesh(MFTM)[6], at the same redundant spare ratio. Especially, with global reconfiguration, the resliability improvement ratio per spare can be at least twice of that of the mFTM scheme. Furthemore, the lower port complexity in spare nodes as compared to those in both of the aforementioned schemes, nd versatility in reconfiguration capability are two additional merits of our proposed architecture.
