ABSTRACT:
A line draw engine for generating Bresenham and DDA lines includes an adder, circuitry for generating a control sign indicative of whether a Bresenham or a DDA line is desired, circuitry for selectively inverting an output of the adder responsive to the control signal and Bresenham line draw logic coupled to the adder and the control signal for drawing a next point responsive to the output of the inverting circuitry.
