Abstract
LAS UNIDADES DE DATOS DE VISUALIZACION SE TRANSFIEREN EN UN SISTEMA DE PC/INTERFAZ DE VISUALIZACION DE GRAFICOS QUE COMPRENDE TRES UNIDADES DE MEMORIA; UNA MEMORIA FUENTE (10) QUE SE DIRECCIONA EN INCREMENTOS DE BYTE PLANARIOS Y ALMACENA UNIDADES DE DATOS DE VISUALIZACION EN BASE A UN BIT POR PLANO; UNA MEMORIA OBJETIVO (42) PARA ALMACENAR UNIDADES DE DATOS DE VISUALIZACION DE UN MODO ADECUADO PARA EL FUNCIONAMIENTO DE UNA UNIDAD DE VISUALIZACION; Y UN BUFFER DE VENTANA (37) PARA TRANSFERIR UNIDADES DE DATOS DE VISUALIZACION DESDE LA MEMORIA FUENTE A LA MEMORIA OBJETIVO. UNA CANTIDAD DE BYTES DE UNIDADES DE DATOS DE VISUALIZACION SE TRANSFIEREN DE LA MEMORIA FUENTE (10) A LA MEMORIA OBJETIVO (42) MEDIANTE EL ACCESO DE PARES DE BYTES PLANARIOS, CUYO PAR DE BYTES PLANARIOS PUEDE TENER UN BYTE DE UNIDAD DE DATOS DE VISUALIZACION DE PUENTE ENTRE ELLOS. EL METODO COMPRENDE LA SELECCION DE UN PRIMER PAR DE BYTES PLANARIOS DE LA MEMORIA FUENTE; LA ALINEACION DEL BYTE DE UNIDAD DE DATOS DE VISUALIZACION QUE ESTA TOTAL MENTE DENTRO DEL PRIMER PAR SELECCIONADO DE BYTES PLANARIOS; LA SELECCION DE UN SEGUNDO PAR DE BYTES DE LA MEMORIA FUENTE; LA ALINEACION DEL BYTE DE UNIDAD DE DATOS DE VISUALIZACION QUE ESTA TOTALMENTE DENTRO DEL SEGUNDO PAR SELECCIONADO DE BYTES PLANARIOS; LA CONSOLIDACION DEL BYTE DE UNIDAD DE DATOS DE VISUALIZACION QUE HACE DE PUENTE ENTRE EL PRIMER PAR Y EL SEGUNDO PAR DE BYTES PLANARIOS SELECCIONADOS; LA ALINEACION DEL BYTE CONSOLIDADO DE UNIDAD DE DATOS DE VISUALIZACION; Y LA TRANSFERENCIA DE LOS BYTES ALINEADOS DE UNIDADES DE DATOS DE VISUALIZACION AL MEDIO DE BUFFER DE VENTANA.
