System and method to manage data processing stages of a logical graphics pipeline
First Claim
1. A system to manage data processing stages of a logical graphics pipeline, comprising:
- a plurality of nonspecialized execution blocks electrically coupled together and to a global spreader that assigns graphics object entities for execution to the plurality of nonspecialized execution blocks, each nonspecialized execution block comprising;
an entity descriptor table configured to contain information about an assigned graphics object entity corresponding to allocation of the entity and a current processing stage associated with the entity;
a stage parser unit configured to establish pointers for one or more processing stages and for the assigned graphics object entity to be processed next on a processing stage;
a data move unit configured for data loads and moves within the nonspecialized execution block, with the global spreader, and with other nonspecialized execution blocks of the plurality of nonspecialized execution blocks; and
a cache memory configured as multiple logical FIFOs with memory references to one or more assigned graphics entities.

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.

13. A method for managing data processing stages of a logical graphics pipeline, comprising:
-
receiving at one or more nonspecialized execution blocks an assignment from a global spreader unit to execute data corresponding to a graphics object entity; allocating a physical buffer containing data associated with the graphics object entity in an entity descriptor table, wherein the entity descriptor table is a component of an nonspecialized execution block; establishing one or more pointers referencing data associated with the graphics object entity contained in the entity descriptor table to be processed on a next processing stage; moving data associated with the graphics object entity within the nonspecialized execution block, to the global spreader, or to another of the one or more nonspecialized execution blocks; and storing data associated with the graphics object entity in a cache memory configured as multiple logical FIFOs. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
