OGA Engine

At the moment just some documentation / notes I've found:

The OGA Engine block diagram.

The software implementation of this can be found in the SVN repository in two versions under the directories model/ and new_model/.

A textual description of the different modules can be found here:

The openGL2.0 specs:

Interaction with the host computer.

For the observant reader, it is possible to see in the block diagram that the graphics engine is lacking the capability to perform vertex operations. For now, it is assumed that the vertex processing will be done in software by the host computer. This is done so we can save gates for rasterization and fragment processing, which are the processor intensive tasks.
