Electronic multiplier circuit with four multiple circuits - has multiple numbers of 2, 3, 4, and 5 and uses partial product adder to produce 54321 product numbers

摘要

The electronic multiplier circuit contains four multiple circuits (1-4) with multiple numbers 2, 3, 4 and 5 and a partial product adder circuit (5) for a maximum of two partial products. The multiple circuits produce their product numbers in 54321 code. The partial product adder circuit is in the form of a special adder circuit with only as many inputs as are actually required. It may contain only one or two dual full adders. ADVANTAGE - Requires only small number of OR circuits.
