A notable feature of ABC95 array computer is the support of complex interconnection, which determines that the computer must have enough I/O band and flexible communications between Pes. The authors designed the interconnecting network chips of ABC95 and realized a form of multi-function interconnection. The multi-function interconnecting network supports conflict-free access from processors to memory matrix and the MESH network of enhanced processors to processor communications. The design scheme has been proved feasible by experiment.展开更多
