Abstract
UNA INTERFASE SIGILOSA PARA UN SISTEMA DE COMUNICACION FRONTAL INTELIGENTE QUE ACOPLA UNA PLURALIDAD DE ORDENADORES DE CONTROL DE PROCESO REDUNDANTES ACTIVAMENTE A UNA MALLA DE ORDENADORES. LA INTERFASE SIGILOSA EN CADA UNO DE LOS ORDENADORES DE CONTROL DE PROCESO REDUNDANTES ACTIVAMENTE INCLUYEN UNA MEMORIA MULTIPORTEADA PARA ALMACENAR LOS DATOS DINAMICOS ASOCIADOS CON EL PROCESO FISICO Y PARA TRANSFERIR ESTE DATO A UN ORDENADOR FRONTAL QUE ESTA EN COMUNICACION CON LA MALLA DE ORDENADORES. LA MEMORIA MULTIPORTEADA TAMBIEN INCLUYE UNA SECCION DE BUZON PARA ALMACENAR LOS MENSAJES ENVIADOS ENTRE EL ORDENADOR FRONTAL Y SU ORDENADOR DE CONTROL DE PROCESO REDUNDANTE ACTIVAMENTE. LA INTERFASE SIGILOSA TAMBIEN INCLUYE UN CIRCUITO GUARDIAN QUE ULTIMAMENTE CONTROLA LA CAPACIDAD DEL ORDENADOR FRONTAL PARA ESCRIBIR LA INFORMACION A LUGARES ESPECIFICOS DE MEMORIA EN LA MEMORIA DE DATOS MULTIPORTEADA.
