Abstract
A low cost vector graphics display processor is capable of being operated by a relatively small processor. Indicia of a predetermined sequence of endpoints defining a figure, and move/draw indicia indicative of connections in the figure between successive endpoints are stored in a coordinate memory. Drive signals for display are generated in accordance with the contents of respective position counters. The contents of current position counters are selectively varied from values corresponding to a second successive endpoint in accordance with the move/draw indicia in a gradual manner to generate drive signals to draw a line between the first and second endpoints or to effect a move on the display without generating a line.
