Abstract
Disclosed are an apparatus, a method, a programmable graphics processing unit (“GPU”), a computer device, and a computer medium to facilitate, among other things, the generation of parallel data streams to effect parallel processing in at least a portion of a graphics pipeline of a GPU. In one embodiment, an input of the apparatus receives graphics elements in a data stream of graphics elements. The graphics pipeline can use the graphics elements to form computer-generated images. The apparatus also can include a transposer configured to produce parallel attribute streams. Each of the parallel attribute streams includes a type of attribute common to the graphics elements. In one embodiment, the transposer can be configured to convert at least a portion of the graphics pipeline from a single data stream to multiple data streams (e.g., executable by multiple threads of execution) while reducing the memory size requirements to implement such a conversion.
