Patent ID: 8139069

Claim:
A method for managing a plurality of independently processed texture streams in a parallel rendering system that includes a plurality of shading engines, comprising: inserting a first time stamp in a first group of tiles of work associated with a first texture stream in the plurality of the texture streams, wherein the first texture stream is processed by a first shading engine within the parallel rendering system, and the first group of tiles is associated with a first area in screen space; inserting a second time stamp in a second group of tiles of work associated with a second texture stream in the plurality of the texture streams, wherein the second texture stream is processed by a second shading engine within the parallel rendering system, and the second group of tiles of work is associated with a second area in screen space; and comparing the first time stamp with the second time stamp to determine a difference between the first time stamp and the second time stamp; based on the difference between the first time stamp and the second time stamp, determining whether one or more corrective operations should be performed to reduce divergence in the processing of the first texture stream and the second texture stream.
