You get a lot for not a lot of money in comparison to writing and validating your own Transaction and Data Link layers for a PCIe PHY. If simplicity is your friend, the extra $31 might possibly be the best money you could spend. On the other hand, if you don't even want to pay $7 for a PCIe PHY - Lattice Semiconductor makes a low cost FPGA with DSP blocks (MAC included, not just MULT) that also have SERDES lines to them. You can even get a quick PCIe dev board from them here: http://www.latticesemi.com/products/developmenthardware/fpgafspcboards/ecp2mpciexpressevaluation.cfm
I'm not sure how to address the IP core issue yet. The Open Graphics project will have to deal with it sooner or later, but I hope we will coordinate efforts. I told them what I had discovered so far, but I'll have to see how that discussion turns out before I can say if it'll be any help. If you know anything about the problems I need to solve, I'd love to hear about it. :)
I am not sure how their IP solution works, but you can try to contact their representatives and try to help figure it all out. It might be very interesting.
I don't have a site yet since so far I have little but a fuzzy picture of what I want to do. I'm still trying to find out if it is actually even doable. The hardware seems possible, even for $100 if I use a slightly cheaper ADC than I'd like, but to then process this massive amount of data I'm rather unsure about. I emailed the FFTW project, since I figure they're the experts, but as of yet I've seen no reply. Might be there's no one checking emails at weekends...
Anything with embedded mults and a clock rate 10 to 20 times higher than your maximum bandwidth would probably be really good - at least for fixed point processing (which I highly recommend).
Once I have gathered a little more real data and can come up with a workable plan I'll probably set up a site of some sort. Maybe a simple blog.
Sounds cool - keep me informed, please!
Thanks for the reply! -- Nos
