Electronic multiplier circuit combined with code conversion circuit - producing BCD-8421 code using only one correction circuit with two auxiliary circuits

摘要

An electronic multiplier circuit is combined with a code conversion circuit which converts the result of the main circuit from dual code into BCD-8421 code. The code conversion circuit has only one correction circuit (40) for adding the correction number 6 or LHHL or subtracting the correction number 10 to HLHL. The code conversion circuit contains only 5 dual full adders (3). It produces the result 63 partially with an auxiliary circuit. ADVANTAGE - Contains only one correction circuit and uses auxiliary circuits for the products 30 and 63.
