Electronic multiplier circuit with special combined circuit - contg. full adder an fewer than 25 and circuits for forming main product

摘要

The product of an electronic multiplier circuit consists in the normal case of a main product, produced by a combined circuit (1) from no more than 5x1 partial products, and a residual product, produced by a residual ficed value circuit (2), which are added together in a suitable adder circuit. The special combined circuit (1) contains, apart from a full adder, fewer than 25 AND circuits, each of which has only two inputs. ADVANTAGE - Circuit is improved by using replacement combined circuit to form main product instead of two circuits.
