Abstract

L'invention concerne les circuits logiques. Le circuit de l'invention est destiné à compter le nombre de <<1>> binaires dans un mot numérique. Ce mot est divisé en deux segments, et deux compteurs 16A et 16B comptent respectivement le nombre de <<1>> dans chaque segment, après quoi un additionneur 12 additionne les signaux de sortie des deux compteurs pour donner le signal de sortie final. Application aux circuits utilisés en informatique.The invention relates to logic circuits. The circuit of the invention is intended to count the number of binary <<1>> in a digital word. This word is divided into two segments, and two counters 16A and 16B respectively count the number of <<1>> in each segment, after which an adder 12 adds the output signals of the two counters to give the final output signal. Application to circuits used in data processing.
