Abstract

UNA (OCRU) (OPTICAL CODE RECOGNITION UNIT ONOCIMIENTO DE CODIGOS OPTICOS) PARA RECONOCER UN CODIGO OPTICO DE N-BITS PREDETERMINADO, TIENE UN DIVISOR (7) DE N-VIAS TENIENDO UNA ENTRADA Y N SALIDAS PARALELAS (7A). UNA PLURALIDAD DE COMBINADORES (8A, 8B. 8C) ESTAN ASOCIADOS CON LAS SALIDAS (7A) DEL DIVISOR, Y UNA PUERTA RESPECTIVA (9A, 9B, 9C) SE CONTROLA POR LA SALIDA DE CADA UNO DE LOS COMBINADORES. CADA UNA DE LAS SALIDAS DEL DIVISOR (7A) ESTA SUJETA A UNA DEMORA DIFERENTE DESDE 0 HASTA (N-1) PERIODOS, Y CADA COMBINADOR (8A, 8B, 8C) RECIBE UNA ENTRADA PROCEDENTE DE, AL MENOS, UNA DE LAS SALIDAS (7A) DEL DIVISOR. LA OCRU ES TAL QUE TODAS LAS PUERTAS (9A, 9B, 9C) SE ABREN SI SE APLICA UN CODIGO OPTICO PREDETERMINADO A LA ENTRADA DEL DIVISOR.
