ABSTRACT:
A character display system which generates analog signals to write sequentially specified strokes forming a character on a display device is described. The character strokes are stored as digital words in a Read Only Memory (ROM) and are sequentially read out in response to instructions to write a specified character. The ROM also contains address words that specify a group of words elsewhere in the ROM that together constitute the instructions for writing the character designated. The address words include fields controlling incrementing within the addressed word group, movement on the display device to a new character space, and positioning of the character space on that display device. Each word in a character word group includes fields representing the X- and Y-end points of the stroke signal, the slope of the X- and Y-components, the blanking and unblanking of the stroke signal, and, in some cases, a pause in movement where a change in slope occurs during execution of a single word. The system permits displacement of the X- and Y-end points in X-, Y- and Z- planes for display on an X-Y coordinate display means. The system also permits modifying the scale of a character, rotating a character in 90.degree. increments, slanting a character, and any combination of displacement, modification, 90.degree. incremental rotation and slanting.
