On new generation dataflow architecture

Dataflow machines execute instructions only when the operands are available. Therefore each execution of instructions are treated as an independent event and exploitation of maximum concurrency at a scalar level, vector level, and function level is achieved. The author describes the architecture of a dataflow supercomputer, SIGMA-1, developed over several years. Since the SIGMA-1 system forms a pipeline through the processing elements and the networks, it can attain a high performance when programs have enough concurrency to supply data to the input buffer of the processing element continuously
