ABSTRACT:
A plurality of vertex or fragment processors on a graphics processor perform computations. Each vertex or fragment processor is capable of executing a separate program to compute a specific result. A combiner manages the combination of the results from the respective processors, and produces a final transformed vertex or pixel value. The vertex or fragment processors and the combiner can be programmable to modify their operations. As such, the vertex or fragment processors can operate in a parallel or serial configuration, or both. The combiner manages and resolves the operations of the serial and/or parallel configurations. A synchronization barrier enables the combiner to perform data-dependency analysis to determine the timing and ordering of the respective processors' execution. A transformation module can include one or more programmable vertex processors that transforms three-dimensional geometric data into fragments. The fragment processors subsequently receive and compute a result for each fragment, which is combined using the combiner to produce the final pixel value.
