Abstract
UNOS BLOQUES DE DATOS SON IDENTIFICADOS ASOCIANDO CON LOS BLOQUES DE UN CICLO DE M BLOQUES LOS RESPECTIVOS BITS DE UN CODIGO DE CADENA DE M BITS. ASI EL NUMERO DE BLOQUE PUEDE SER DECODIFICADO EN UNA ROM A PARTIR DE CUALESQUIERA N SUCESIVOS BITS DE CODIGO, SIENDO 2N-1 MAYOR QUE O IGUAL A M. PARA ACELERAR EL PROCESO DE IDENTIFICACION UNA PLURALIDAD S DE BITS DE CODIGOS SUCESIVOS DEL CODIGO DE LA CADENA DE M BITS ES ASOCIADA A CADA BLOQUE. PARA IDENTIFICAR UNICAMENTE EL NUMERO DE BLOQUE S Y M SON PRIMOS ENTRE SI, Y LOS BITS DEL CODIGO CONSULTAN SOLO UNA VEZ CADA S BITS DE CODIGO. EL TAMAÑO DE LA ROM DECODIFICADORA NO NECESITA AUMENTARSE.
