Abstract
A method and apparatus for processing hierarchical graphics data from an application. The data processing system includes a plurality of threads in which a first thread receives graphics data from the application. The data stream is partitioned into workgroups and a sequence number is associated with each workgroup identifying the order in which the workgroup should be processed. Each thread processes a unique portion of the workgroups. Processed workgroups are stored in a memory associated with the thread processing that workgroup. The primary thread dispatches the processed workgroups from each of the memories associated with the threads to a rasterizer for the graphics display device. The workgroups are dispatched in an order indicated by the sequence number associated with each processed workgroup.
