Abstract

SE DESCRIBE UN CONTROL DUPLICADO Y UNA UNIDAD DE PROCESAMIENTO PARA UN EQUIPO DE TELECOMUNICACIONES QUE CONSTA DE DOS UNIDADES DE CONTROL IDENTICAS CONECTADAS CONJUNTAMENTE. CADA UNIDAD DE CONTROL (UC0,UC1) COMPRENDE UNA UNIDAD DE PROCESAMIENTO (UP0,UP1) LAS CUALES PUEDEN ESTAR ACTIVAS O EN ESPERA, UNA MEMORIA DE ACCESO ALEATORIA DE DATOS PERIFERICA (RAM) PARA EL PROCESO DE DATOS DURANTE LA OPERACION, Y VARIOS CIRCUITOS PERIFERICOS CONECTADOS AL RESTO DEL EQUIPO. UN EPROM (MEMORIA SOLO DE LECTURA PROGRAMABLE BORRABLE) (CCL0,CCL1) EN CADA UNIDAD DE PROCESAMIENTO CONTIENE EL FIRMWARE DE SELECCION DE COPIA. LA RAM DE DATOS Y LOS CIRCUITOS PERIFERICOS INCLUYEN UN CIRCUITO DE ACCESO DE DOBLE PUERTA RESPECTIVA (ACC0,ACC1) QUE PERMITE EL ACCESO SELECTIVO SOLO AL PROCESADOR ACTIVO. ESTE ULTIMO REALIZA LOS CICLOS DE ESCRITURA SINCRONIZADAMENTE SOBRE AMBOS RAMS DE DATOS DUPLICADOS, PERMITIENDO LA RECUPERACION RAPIDA DEL SINCRONISMO OPERATIVO MEDIANTE LA UNIDAD PROCESADORA DE ESPERA, TRAS LA INTERRUPCION DEBIDA AL FALLO DE LA UNIDAD PROCESADORA ACTIVA.
