This paper presents a high-speed multiplication algorithm for the mixed number system of the ordinarybinary number and the symmetric redundant binary number.It is implemented with the multivalned logictheory,and 3-valued and 2-valued circuits are used.The 3-valued circuit proposed in this paper is anemitter-coupled logic circuit with high speed,simplicity and powerful functions.A 3-valued ECL thresholdgate can simultaneously produce six types of one-variable operations.The array multiplier,designed withthe algorithm and the circuits,is fast and simple,and is suitable for building LSI.It can be used in a high-speed computer just as an ordinary binary multiplier.
