Abstract

EN UN APARATO DE REGISTRO DE SEÑALES DIGITALES QUE HACE USO DE UNA MODULACION I-NRZI PARA EL REGISTRO, SE ELIMINA LA NECESIDAD DE UNA LECTURA INTERMITENTE O DE UNA ESCRITURA INTERMITENTE EN LA MEMORIA INTERMEDIA MEDIANTE LA UTILIZACION DE UNA PRECODIFICACION DE BITS PARALELOS PARA GENERAR LAS PALABRAS DE CANAL QUE SE SELECCIONAN PARA EL REGISTRO. LOS PRECODIFICADORES (106) REALIZAN UNA PRECODIFICACION ACELERADA UTILIZANDO UNA INTEGRACION DE ALTA VELOCIDAD DE LOS BITS SUCESIVOS ALTERNOS UTILIZADOS PARA FORMAR CADA PALABRA DE CANAL. DOS PRECODIFICADORES (106) GENERAN PALABRAS DE CANAL DE BITS PARALELOS (N+1) A UNA VELOCIDAD DE PALABRAS DE CANAL MENOR EN UN FACTOR (N+1) QUE LA VELOCIDAD DE UN RELOJ DEL SISTEMA PARA LA MODULACION I-NRZI. ESTO DEJA UN TIEMPO ADICIONAL DURANTE CADA INTERVALO DE PALABRA DE CANAL PARA LLEVAR A CABO UN PROCESO DE DECISION, QUE DETERMINA CUAL DE LAS PALABRAS DE CANAL GENERADAS POR LOS DOS PRECODIFICADORES SE VA A SELECCIONAR PARA SU REGISTRO. TAMBIEN HAY TIEMPO ADICIONAL SUFICIENTE PARA TERMINAR UN PROCESO DE ACTUALIZACION SUBSIGUIENTE, EN EL QUE LA INFORMACION DE PRECODIFICACION ALMACENADA EN EL PRECODIFICADOR QUE NO GENERO LA PALABRA DE CANAL SE ALTERA, DE MODO QUE COINCIDA CON LA INFORMACION DE PRECODIFICACION ALMACENADA EN EL PRECODIFICADOR QUE GENERO LA PALABRA DE CANAL SELECCIONADA. LAS PALABRAS DE CANAL DE BITS PARALELOS PROCEDENTES DE LOS PRECODIFICADORES SE CONVIERTEN EN UN FORMATO DE BITS EN SERIE CON UNA VELOCIDAD DE TRAFICO DE BITS SUSTANCIALMENTE SUPERIOR A LA DEL RELOJ DEL SISTEMA, PARA OBTENER UNA SEÑAL PARA LLEVAR A CABO A TIEMPO LOS PROCESOS DE DECISION Y DE ACTUALIZACION.
