Electronic multiplier circuit - combines main and residual products in adder circuit contg. fewer than 6 adder circuits apart from full adder

摘要

The product of an electronic multiplier circuit consists in the normal case of a main product, produced by a combined circuit from no more than 5x1 partial products, and a residual product whcih are added together in a suitable adder circuit. The adder circuit (6), apart from a full adder (26), contains fewer than 6 AND circuits, each of which has only two inputs. USE/ADVANTAGE - Improved by being significantly simplified intermediate result being produced in 51111 code instead of 54321 code.
