Abstract: A transaction elimination hardware unit controls the writing to a frame buffer in a memory of tiles generated by a tile-based graphics processor. The transaction elimination hardware unit has a signature generator that generates a signature representative of the content of the tile for each tile. A signature comparator then compares the signature of a new tile received from the graphics processor with the signatures of one or more tiles already stored in the frame buffer to see if the signatures match. If the signatures do not match, then the signature comparator controls a write controller to write the new tile to the frame buffer. On the other hand, if the signatures match, then no data is written to the frame buffer and the existing tile is allowed to remain in the frame buffer. In this way, a tile is only written to the frame buffer if it is found by the signature comparison to differ from the tile or tiles that are already stored in the frame buffer that it is compared with.

Abstract: A profiler for a ray tracing renderer interfaces with the renderer to collect rendering information, such as ray definition information, a pixel origin, objects hit, shader invocation, and related rays. In an interface, an artist views a simplified 3-D scene model and a rendered 2-D image.

Statistics can be produced by the profiler that convey information such as relative computational complexity to render particular pixels. The profiler can step through multiple passes (e.g., multiple frames and passes of a multipass rendering), and the UI can allow pausing and stepping.
