Abstract

1,243,865. Decimal-to-binary converters. MESSERSCHMITT - BOLKOW - BLOHM G.m.b.H. 29 Aug.. 1969. [5 Sept.. 1968], No. 43207/69. Heading G4A. A BCD-to-pure-binary converter comprises a number of binary full adders, each (except the last) feeding sum and carry signals to the next, and each BCD input line (except the least significant) going to all the adder inputs associated with those powers of two which added together give the value of the input line. As disclosed, six 4-bit parallel binary adders are used for three decimal orders, each except the last feeding three sum bits and a carry bit to the next and providing one bit of the final binary output. The last adder provides four bits of the output.
