Abstract

See full text

The numbers of gates necessary in an integrated combinatorial logic circuit is reduced by designing the circuit to accept an applied binary word of given length as a plurality of word segments having numbers of bits which add up to the number included in the applied word. A preprocessor responds to the word segments to generate a word characterizing the segments and to apply those words to an arithmetic logic unit designed to add binary words and to generate words having lengths of the applied words.
