ABSTRACT:
Systems and method for providing shared attribute evaluation circuits in a graphics processing unit are provided. One embodiment can be described as a system for evaluating attributes in a graphics processing unit having a plurality of processing stages. The system can include an evaluation block, configured to process a plurality of attributes corresponding to a plurality of pixels and a plurality of FIFO buffers, each configured between one of the plurality of processing stages and the evaluation block. An embodiment can further include a shared buffer, configured to store the plurality of attributes or pointers during the attribute processing and processing priority logic, configured to determine a plurality of priorities corresponding to the plurality of attributes.
