Abstract

UN METODO PARA PROBAR UN CANAL DE SEÑALES O DE SEÑALAMIENTO DE UN SISTEMA QUE TIENE UN CICLO DE OPERACION Y SISTEMA DE VERIFICACION CORRESPONDIENTE, EN DONDE SE PROPORCIONAN CONTINUAMENTE FRECUENCIAS DE PRUEBA DE BITS MULTIPLES DURANTE SUBPARTES SUCESIVAS DEL CICLO DEL PROCESADOR A INTERCONEXIONES DE SALIDA QUE, DEPENDIENDO DE SU ESTADO, INVIERTEN LOS BITS DE LAS SEÑALES O NO LOS DEJAN PASAR. UN COMPILADOR CON MEMORIA RAM DIRIGIDA POR MEMORIA ROM ESTA CONFIGURADO PARA DIVIDIR POR POLINOMIOS DIRECTOS E INVERSOS EN PARTES ALTERNAS DEL CICLO DEL SISTEMA. DESPUES DE CADA UNA DE ESTAS PARTES SE CONSTRUYEN PALABRAS DE VERIFICACION UTILIZABLES PARA COMPROBAR LA OPERACION VITAL DEL SISTEMA Y APLICABLES A UN DESCODIFICADOR VITAL QUE CONTROLA LAS INTERCONEXIONES DE SALIDA Y ACONDICIONA LA SALIDA AL ESTADO RESTRICTIVO AL DETECTARSE UN FALLO DE CICLO DEL SISTEMA. EL INVENTO ES APLICABLE A SEÑALIZACION Y CONTROL DE FERROCARRILES.
