Abstract

DISPOSITIVO DE SELECCION DE PAGINA PARA SISTEMA DE TELETEXTO. UN PAQUETE DE DATOS SE INTRODUCE EN UN TAMPON DE ENTRADA (1), EN UN TAMPON AUXILIAR (3), AMBOS COMPUESTOS POR MEMORIAS FIFO, Y EN UN CIRCUITO DE IDENTIFICACION (4) QUE CONTROLA LOS DOS ANTERIORES. SI EL PAQUETE CONTIENE UNA BANDERA DE PAGINA LOS DATOS LLEGAN A UN TAMPON PRINCIPAL (2) CONSTITUIDO POR UNA MEMORIA FIFO, Y SON INSCRITOS EN EL TAMPON AUXILIAR (3). LOS DATOS DE ESTE Y LOS ELEGIDOS POR EL USUARIO MEDIANTE UN SELECTOR (6), SON COMPARADOS EN UN COMPARADOR (5). SI EL RESULTADO ES POSITIVO SE MANDA SEÑAL AL TAMPON PRINCIPAL (2) PARA VISUALIZAR LOS DATOS INSCRITOS EN EL.
