ABSTRACT:
An apparatus, system, and method for clipping graphics primitives are described. In one embodiment, a graphics processing apparatus includes a clipping unit, a read-only memory that is connected to the clipping unit, a read-write memory that is connected to the clipping unit, and an addressing unit that is connected to the read-only memory and the read-write memory. The read-only memory is configured to store a clipping program, and the read-write memory is configured to store a patch program. The addressing unit is configured to selectively address one of the read-only memory and the read-write memory based on a set of input conditions.
