Economic budget or time budget? Do we have an idea of how much larger the die would be? I suspect the main problem would be design time. > > 2) Partly in CPU, partly in TRV chip? > > from previous discussion, this may be difficult > > or impossible? > > The only way IMHO. But I keep reading that large amounts of data have to go back and forth between CPU and GPU? Would PCIe x16 be enough? There are other ways, like putting the GPU on the hypertransport bus, but that would *greatly* reduce the mainboards you could use. You could put a CPU on the OGC card, but that would increase the economic cost and power&heat cost significantly. > > 3) wait for AMD to sell a AMD64 30,000+ x16 CPU? > > Impossible, light isnt that fast. IIRC they now have 6000+ x2, so they only have to find a 5x speed improvement. (And of course I just made up the 30,000 number, I don't know what the real requirement would be.) I read that Barcelona will have 128 bit SSE instructions and x4. I assume they will eventually have a CPU that is fast enough to decode video and also do other things at the same time. And a few years later it will be affordable. Question is how long do we have to wait, and will we live long enough to see it? > > 4) wait for TI to sell a faster DSP? > > DSPs wont help as much as you think.

If TI can bump the speed up 2x or so (just a guess) it should be fast enough.

I assume someone makes a chip that decodes in hardware that these things use? If so, then it is possible to do in hardware. What really matters is that we have documentation on how to talk to the board, allowing device drivers to be written. If that is possible, we could hold our nose and use a NDA'd chip. Depends on what information they will make available. Some companies will not tell you what you need to know even with a NDA. > > 6) something else? > > Keep the current aproach. Which is basically the same as 3 - wait for a super fast CPU. And kiss a big part of the market goodbye. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
