Abstract

DISPOSITIVO PARA LA SINCRONIZACION DEL FUNCIONAMIENTO DE COMPUTADORES CON LA SEÑAL DE SINCRONISMO DE VIDEO. EL MICROORDENADOR SE PROGRAMA PARA MUESTREAR PERIODICAMENTE LA SEÑAL DE VIDEO COMPUESTA, A FIN DE DETERMINAR LA POSICION DE LA COMPONENTE DE SINCRONIZACION Y HACER FUNCIONAR LA PUERTA EN EL SENTIDO DE ANULAR LOS IMPULSOS DE RELOJ HASTA QUE LA APARICION DE LA INSTRUCCION DE MUESTREO SE ALINEA EN FASE CON LA APARICION DE LA COMPONENTE DE SINCRONIZACION. LA SEÑAL DE RELOJ SE GENERA CONTROLANDO SU FASE Y FRECUENCIA EN RESPUESTA A UNA SEÑAL DE CONTROL. SU FRECUENCIA ES UN MULTIPLO ENTERO DE LA FRECUENCIA DE REFERENCIA. EL MICROORDENADOR PUEDE RESPONDER A LA SEÑAL DE FRECUENCIA VERTICAL, CONTANDO EL NUMERO DE VECES QUE DICHA SEÑAL DE COMPARACION ES GENERADA. SE PREVE UNA FUENTE DE SUMINISTROS DE SEÑALES DE DATOS CORRESPONDIENTES A UN CARACTER, A LOS QUE EL COMPUTADOR ES CAPAZ DE RESPONDER GENERANDO LOS IMPULSOS <DE CARACTER> NECESARIOS.
