Dual multiplier-divider circuit based on multiplier circuit - converts binary to BCD-8421-code in fixed value circuits with no end stages and hence no transistors

摘要

A dual electronic multiplier-divider circuit which processes 1-from-10-coded decimal numbers converts them into binary code via fixed value circuits with no end stages and hence no transistors. It produces results in BCD-8421-code. The conversion from binary to BCD-8421-code is also performed by a fixed value circuit and may involve serial additions. Addition of BCD-8421-coded partial numbers is performed by a special adder circuit contg. a correction circuit for addition of 6. Results are transferred into the result shift register by 4-bit parallel input. USE/ADVANTAGE - A multiplier-divider is based on the multiplier circuit of P3934898.9.
