ABSTRACT:
A system and method to manage data processing stages of a logical graphics pipeline comprises a number of execution blocks coupled together and to a global spreader that assigns graphics data entities for execution to the execution blocks. Each execution block has an entity descriptor table containing information about an assigned graphics data entity corresponding to allocation of the entity and a current processing stage associated with the entity. Each execution block includes a stage parser configured to establish pointers for the assigned graphics data entity to be processed on a next processing stage. A numerical processing unit is included and configured to execute floating point and integer instructions in association with the assigned graphics data entity. The execution blocks include a data move unit for data loads and moves within the execution block, with the global spreader, and with other execution blocks of the plurality of execution blocks.
