Abstract
An inventive line-drawing apparatus draws a line that connects a start point to an end point. The start and end points are both presented on a display and represented by mutually different sets of coordinates. The apparatus includes first and second FIFO memories, an adder and a shifter. Each of the first and second FIFO memories accepts a plurality of input coordinate data and sequentially outputs one of these data after another on a first in, first out basis. The adder receives and adds together the respective coordinate data output from the first and second memories and outputs added data. And the shifter divides the added data by two and outputs divided data. The coordinate data output from the first and second memories are input to the first memory. The divided data is input from the shifter to the second memory. The line connecting the start and end points together is drawn on the display in accordance with the divided data output from the shifter.
