Abstract
Improvements in graphics processing pipelines are disclosed. The graphics processing pipeline processes graphics objects in a particular order (application programming interface order—'API order') as requested by an application or other entity. However, certain components within the graphics processing pipeline, such as the pixel shader stage, may process those objects out of order. A technique is provided herein to allow the pixel shader stage to complete and export processed fragments out of order. The technique includes using a scoreboard to determine whether fragments ready to be exported from a pixel shader stage are the newest fragments in API order. If the fragments are the newest in API order, then the fragments are exported. If the fragments are not the newest in API order, then the fragments are discarded.
