Graphics architecture help...

[Michael Amster]

I am doing a review of graphic coprocessors and speed-up boards for
workstations for a Computer Architecture class.  I have found information
on the TI TMS34020, but have been unable to find references for some other
systems.  I am particularly interested in the IRIS 4d architecture and the
SUN (GP? or GX?) add-in board.

If you know of any articles that appeared in journals or of a way to get
company literature on the architecture of these systems, please reply to
me via e-mail as I do not read these groups regularly.  Any help would be
appreciated.
