Abstract

SIGMA-1 is the most exciting practical computer prototype with dataflow architecture. The project aims to outperform conventional von Neumann computers. This large-scale dataflow computer, for scientific and technological computations, is in the final stage of the design and construction phase at the Electrotechnical Laboratory, Ministry of International Trade and Industry.This paper overviews the system architecture of the SIGMA-1, and discusses the performance measurements made recently. The architectural issues in dataflow computing machines and the design decisions made in the SIGMA-1 project in achieving 100 MFLOPS performance are presented. The history of the SIGMA-1 project is also outlined.
