Global spreader and method for a parallel graphics processor

摘要

A parallel graphics processor having a spreader coupled to a plurality of execution components is disclosed. The spreader maintains status information for each of the plurality of execution components and establishes a priority for each of the plurality of execution blocks to receive a graphics entity to be processed. The priorities are arranged in accordance with the maintained status information and a type of graphics entity to be processed. The spreader communicates a request to a selected execution component to allocate the graphics entity to be processed in its entity descriptor table and copies graphics entity data to the selected execution component. The spreader indexes assignment of the graphics entity in its logical table and subsequently receives indication from the selected instruction execution component that the graphics entity has been processed. Thereafter, graphics images may be presented on a display.
