Abstract
A BCD to binary converter, particularly applicable for large numbers, employing an input level of code converter logic comprising PROM groups which provide a specially chosen initial conversion of the BCD number to be converted. Each PROM group comprises a plurality of individually programmed PROMs which provide for this initial conversion by directly converting successive sequential pairs of BCD digits into equivalent binary numbers taking into account their order of significance. A binary adder employing a plurality of PROM logic levels then provides for the binary addition of the binary bits produced by this initial conversion to provide the desired overall BCD to binary conversion.
