An accelerated graphics processing subsystem that significantly increases
the processing speed of computer graphics commands. The preferred
embodiment of this invention presents a first-of-its-kind graphics
processing subsystem that combines the processing power of multiple,
off-the-shelf, video cards, each one having one or more graphic processor
units. The video cards can be used without substantial modification.
Under the preferred embodiment, each video card processes instructions
for drawing a predetermined portion of the screen which is displayed to
the user through a monitor or other visual output device. The invention
harnesses the power of multiple video cards without suffering from the
high bandwidth constraints affecting prior attempts at parallel graphics
processing subsystems.
