Abstract

UN GENERADOR DE BITS DE ENCAMINAMIENTO (42) ESTA ASOCIADO A UNA O VARIAS REDES OMEGA INVERTIDAS EN L FASES Y 2{SUP,N} ENTRADAS. 2{SUP,N} BITS DE ESTADOS (CA) QUE INDICAN SI LAS CELULAS A ENCAMINAR ESTAN LIBRES U OCUPADAS, SE CARGAN EN PARALELO EN UN REGISTRO DE ESTADO (SRE), Y DESPUES SE DECALAN EN SERIE EN ESTE REGISTRO. LOS BITS DE ESTADO SUCESIVAMENTE SUMINISTRADOS POR LA SALIDA EN SERIE (SSE) DEL REGISTRO DE ESTADO, SE FILTRAN SI L < N, SIRVEN PARA INCREMENTAR UN SECUNDO CONTADOR (47) (CA=1) O PARA RESTAR UN SEGUNDO CONTADOR (48) CA=0) Y PARA SELECCIONAR UNO U OTRO CONTADOR (47, 48) EN LA ENTRADA DE UN MULTIPLEXOR (50). RECIBIENDO L REGISTROS DE DIRECCIONAMIENTO (SRO-SR3) EN MODO DE DECALAJE EN SERIE LOS L BITS DE DIRECCION PROPORCIONADOS POR EL MULTIPLEXOR (50), ESTAN DISPUESTOS EN CASCADA DE MANERA QUE DESPUES DE 2{SUP,N} CICLOS DE DECALAJE EN SERIE, SUS CONTENIDOS PUEDAN SER TRANSFERIDOS EN PARALELOS HACIA MEDIOS (40) QUE INSERTAN LOS BITS EN LA CABEZA DE LAS CELULAS.
