ABSTRACT:
An apparatus, system, and method for clipping graphics primitives are described. In one embodiment, a graphics processing apparatus includes a clipping unit that is configured to issue an initial set of outputs based on execution of a set of clipping operations. The graphics processing apparatus also includes a control unit that is connected to the clipping unit. The control unit is configured to preserve an initial execution state of the clipping unit in response to an initial command for context switching, and the initial execution state is preserved based on a number of the initial set of outputs.
