Fault tolerant multi-processor communication systems using bank memory switching

The paper proposes a new fault tolerant communication scheme for real-time operations and three new interconnection networks to construct a fault tolerant multi-processor system for pipeline processings. The proposed communication scheme using bank memory switching technique has an advantage to make a fault tolerant pipeline system so that it can detect any failure caused in a processing element of the system. In addition, it can overcome conventional problems caused in interconnection circuits to data flow with one direction such as a pipeline processing
