Abstract

CONTADOR ELECTRONICO DEL TIPO UTILIZADO EN EL CUENTAKILOMETROS DE UN VEHICULO A MOTOR, QUE INCLUYE UNA MATRIZ (10) DE M LINEAS Y N COLUMNAS DE DISPOSITIVOS DE ALMACENAMIENTO DEL TIPO FLIP-FLOP UNICO Y UNA UNIDAD DE DESPLAZAMIENTO CENTRAL (CSU) (14). LA CSU (14) INCLUYE UNA LINEA DE N DISPOSITIVOS DE ALMACENAMIENTO DE DATOS (13) DISPUESTOS PARA LEER Y PARA ESCRIBIR DATOS EN Y A PARTIR DE CADA UNA DE LAS M LINEAS DE DISPOSITIVOS DE ALMACENAMIENTO DE DATOS DE LA MATRIZ (10). DURANTE EL FUNCIONAMIENTO, LA CSU (14) EFECTUA LA LECTURA DE LOS DATOS A PARTIR DE UNA LINEA DE DISPOSITIVOS DE ALMACENAMIENTO DE DATOS DE LA MATRIZ, EFECTUA UNA OPERACION DE DESPLAZAMIENTO EN LOS DATOS Y UNA OPERACION DE INVERSION EN UNO DE LOS N DISPOSITIVOS DE ALMACENAMIENTO DE DATOS DE LA CSU (14) Y DEVUELVE LOS DATOS EN LOS CUALES SE HA ACTUADO DE ESTA MANERA A LA LINEA DE DISPOSITIVOS DE ALMACENAMIENTO DE DATOS DE LA MATRIZ (10). ESTAS ETAPAS PERMITEN REALIZAR EN LOS DATOS UNA OPERACION DE RECUENTO EN CODIGO JOHNSON.LA INVENCION UTILIZA MENOS SUPERFICIE DE CHIP QUE LOS CONTADORES CONOCIDOS.
