Abstract

ELEMENTO DE CONMUTACION PARA COMUNICACIONES Y METODO PARA TRANSMISION DE CELULAS DE LONGITUD VARIABLE. EL ELEMENTO DE CONMUTACION SE USA PARA TRANSFERIR, ENTRE X ENTRADAS (IL-IX) E Y SALIDAS (01-0Y), CELULAS DIVIDIDAS EN SUBCELULAS DE LAS QUE SOLO LA PRIMERA CONTIENE INFORMACION ACERCA DE LA(S) SALIDA(S) DE DESTINO DE LA CELULA. ESTE ELEMENTO DE CONMUTACION INCLUYE: -UNA MEMORIA DE ALMACENAMIENTO TEMPORAL (BM) CON UNA PLURALIDAD DE POSICIONES DE MEMORIA (C), CADA UNA CON SU DIRECCION (K); Y -MEDIOS DE GESTION DE MEMORIA (BMMU) PARA PROPORCIONAR DIRECCIONES DE POSICIONES DE MEMORIA LIBRE PARA ALMACENAR LAS SUBCELULAS, Y PARA ALMACENAR (BQ1-BQY, SLM), BAJO LA FORMA DE LISTAS ENLAZADAS, LAS DIRECCIONES DE POSICIONES DE MEMORIA USADAS POR LAS SUBCELULAS, ESTANDO CADA LISTA ASOCIADA A UNA CELULA DISTINTA. EL METODO ES ADECUADO PARA PROCESAR CELULAS DE LONGITUD VARIABLE DIVIDIDAS EN SUBCELULAS, CONTENIENDO CADA UNA UN ENCABEZAMIENTO PARA DISTINGUIR UNA PRIMERAÑULTIMA SUBCELULA DE UNA CELULA DE LAS DEMAS SUBCELULAS. SE USA UNA LOGICA DE SUBCELULAS (SL) PARA DETECTAR LA SUCESION EN CUALQUIER ORDEN DE UNA SUBCELULA PERTENECIENTE A UNA CELULA Y UNA PRIMERAÑULTIMA SUBCELULA DE OTRA CELULA O UNA SUBCELULA NO PERTENECIENTE A NINGUNA CELULA, CON EL FIN DE IDENTIFICAR LA ULTIMA/PRIMERA SUBCELULA DE UNA CELULA.
