Abstract: A data processing system which has a processor which issues a key sensing signal when waiting for the input of data; a discriminator connected to the processor for judging whether a key sensing signal is received from the processor and for generating a first signal; a controller for generating a second signal in response to the first signal received from the discriminator; and a switch for selecting one of a plurality of clock signals of different frequency to be sent to the processor in response to the second signal received from the controller. Generation of the second signal can be delayed by a first predetermined time, and a second predetermined time during which the key sensing signal is not received can be measured, whereby it is unnecessary to modify an application program to control the supply of power to the processor and only modification of a key sensing routine (BIOS) enables realization of positive power saving.

Abstract: A method of drawing figures for a multi-window system in which a plurality of window regions are set on a display screen, and in which a window which is partly overlapped on other windows and is partly concealed is controlled by being divided into a plurality of display or non-display subregions, and the displayed content is changed by designating the window. If a dot constituting the figure is generated from a dot generator, coordinate values of the dot are compared with position data of the designated window to select a dot located in the window. The selected dot is compared with position data of a subregion that constitutes the designated window to find a particular subregion in which the dot exists. If the particular subregion is a display region, the dot located therein is produced on the display screen. A dot generated next is compared with the particular subregion and is determined to be displayed or not.

Abstract: The tangent .alpha. of the tangential line of an image to be drawn at each point in an orthogonal X-Y coordinate system is classified into two angle regions, a first angle region, where a condition -1.ltoreq..alpha.<1 is fulfilled, and a second angle region, where a condition .alpha.<-1 or 1.ltoreq..alpha. is fulfilled. The first and the second angle region is represented by the direction parallel to the X-axis and the direction parallel to the Y-axis, respectively. When the image to be drawn is displayed on a display screen, in the image to be drawn, the parts belonging to the first angle region are drawn with a plurality of segments, each of which is parallel to the X-axis, and the parts blonging to the second angle region are drawn with a plurality of segments, each of which is parallel to the Y-axis. That is, the image to be drawn is displayed on the display screen by using only segments parallel to the X-axis and those parallel to the Y-axis.
