Abstract

LOS DATOS DE PANTALLA, ELABORADOS PARALELAMENTE EN DOS CANALES INDEPENDIENTES ENTRE SI, QUEDAN ARCHIVADOS EN MEMORIAS DE PANTALLA (BWS1, BWS2) DE DOS COMPUTADORES (VC1, VC2) DE PANTALLA Y VUELVEN A SER LEIDOS, POR OBRA DE LA SEÑAL DE UN SISTEMA SUBORDINADO DE ORDENADOR, SEGUN LA TECNICA DE LAS SEÑALES, PROCEDENTE DE CALCULADORES DE PANTALLA Y EN ESTA OPERACION SE UNE CON UN POLINOMIO DE REDUNDANCIA. LAS REDUNDANCIAS DE PRUEBA, ASI FORMADAS, SE TRANSFIEREN AL SISTEMA SUBORDINADO PARA SU COMPARACION. EL SISTEMA SUBORDINADO DESENCADENA UNA REACCION DE SEGURIDAD, CUANDO LAS REDUNDANCIAS DE PRUEBA NO SINTONIZAN O NO COINCIDEN EN EL TIEMPO.
