A few changes have been made to the video controller since you last worked on it. Some changes we want to keep, some we don't want to keep. We need the hacked video controller "merged" with the one you worked on and cleaned up a bit. In addition to the video controllers, there are blocks of logic that drive the pins for the various video devices. One head has RGB, DVI, and TV. The other head had just DVI. There are lots of shared pins. There are existing code blocks that would make a good starting place, but they need to be documented properly and cleaned up. Some devices want DDR. How the pixel bits are divided up is different for each one, etc. And yet, everything has to come together into the same set of output registers and buffer drivers. -- Timothy Normand Miller http://www.cse.ohio-state.edu/~millerti Open Graphics Project _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
