Note that Timothy's reply is from his viewpoint of ongoing research within the project. The project produced a working framebuffer hardware, the OGD1, more than two years ago: http://www.traversaltech.com/products.html http://wiki.opengraphics.org/tiki-index.php?page=OGD1 http://www.linuxfund.org/projects/ogd1/ I would suggest to make use of the OGD1 design in an opencores ASIC, until the project has made further progress on the GPU side that Timothy described. I think doing so would generate much interest, and ultimately perhaps more contributors.

I guess no? //Peter _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
