That would be my job I guess :-).
Roughly in order from PCI connector to screen we have:
In the XP10:
A PCI controller (was there already, some work done on getting it into
the XP10, needs testing)
A first version PCI address decoder (new)
A first version of the bridge (new)
HQ (was there already, but with some improvements)
An SPI controller (was there already)
In the Spartan:
A first version of the bridge (new)
A first version of the memory arbiter (new)
A working memory controller (was there already)
A working video controller (was there already)
And we have a bunch of top-level files for these, which need to be
checked for correctness. Then we need to work on synthesis and
optimisation.
The interfaces between these parts are also mostly defined. The main one
missing is the interface between HQ and the things around it (PCI and
bridge). Some more discussion on how that will work is needed, but it
shouldn't be a problem.
Also see http://wiki.opengraphics.org/tiki-index.php?page=VGACodeSprint
which was updated a few days ago.
