Abstract

ESTE PROCESO CONSISTE EN HACER EJECUTAR EL PROGRAMA DE APLICACION A LO LARGO DE CICLOS DE TIEMPO REAL SECUENCIADOS POR UNA SEÑAL DE RELOJ DE TIEMPO REAL (HTR) CUYO PERIODO RECURRENTE (T) PRESENTA DOS ESTADOS SUCESIVOS (T1, T2), EN HACER DETECTAR POR EL PROCESADOR (1) LA TRANSICION DE ESTA SEÑAL QUE MARCA EL INICIO DE CADA PERIODO (T) Y LA MEMORIZACION DE LA HORA EN TIEMPO REAL A LA QUE SE HA PRODUCIDO ESTA TRANSICION EN UN REGISTRO DE COHERENCIA DE UN CIRCUITO DE VIGILANCIA (2), EN VERIFICAR QUE LA MEMORIZACION SE HA EFECTUADO A LO LARGO DEL ESTADO (T1), EN COMPARAR EL CONTENIDO DE ESTE REGISTRO CON LA HORA EN TIEMPO REAL DETERMINADA PARALELAMENTE POR EL CIRCUITO DE VIGILANCIA (2) Y EN TRANSMITIR UNA SEÑAL DE DEFECTO CUANDO DICHA VERIFICACION Y DICHA COMPARACION HAN REVELADO UNA ANOMALIA. LA INVENCION SE APLICA PARTICULARMENTE A LA VIGILANCIA DE LOS PROCESADORES A BORDO DE AERODINOS.
