SIGMA-1 is a large-scale computer based on fine-grain dataflow architecture designed to show feasibility of fine-grain dataflow computer to highly parallel computation over conventional von Neumann computers. SIGMA-1 project was stated on 1984 and the 128 processing element (PE) started working on 1988. SIGMA-1 was design and built at the Electrotechnical Laboratory (ETL for short), Ministry of International Trade and Industry, Japan. SIGMA-1 is still the largest scale dataflow computer so far built and it achieved more 100 Mflops as a maximum measured performance of the total system. As for the language for SIGMA-1, ETL developed Dataflow-C language as a subset of C programming language. Dataflow-C is a single assignment language that can compile C-like source programs to highly parallel executable dataflow machine codes (Fig. 1 ).
