You have a point, and what we may be forced to do is build some prototype boards different form OGD1 to test these differences, or we could just build a daughterboard for the hirose connector. There are many things about TRV10 that we can't predict. So we use OGD1 to do the basic development of OGA, but also we've designed OGD1 to be its own product with its own range of uses. Most likely, we'll want to try to build all of the TV logic into the TRV10 chip, along with DACs. For that, we can design our own TV encoder and test it out on OGD1 with less other logic in it. Then for the final FPGA integration tests, we build some OGD1 boards with 3S5000 chips and put it all together. TRV10 is far enough off that we can't concern ourselves with it too much right now. Right now, we need to focus on OGD1, selling that, and using it as the basis for many sorts of open hardware projects besides just graphics. If you try to sell it as a graphics card, people don't see the point, because it's so expensive. But if you sell OGD1 as a programmable platform into which you can put a graphics engine or countless other options, people will see it as being worth the cost. -- 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)
