It looks like I'll have to slog through a series of introductory posts, just to be able to send private messages.
I'm interested in developing bitcoin miners using new cutting edge FPGA's from Xilinx. I am targeting the new Artix and Kintex family, which look like they can hit extremely high MHashes/Watt.
My first trials have been using the VHDL code posted by Olaf.Mandel here: http://forum.bitcoin.org/index.php?topic=22426.msg300906#msg300906
I'm targeting 3 parallel cores running at 200 MHz each for a hash rate of 600 MH/sec. The power is phenomenal in the .9V low power part, only 5.2 watts, giving a figure of merit well over 100 MHashes/watt.
These parts are available now in engineering samples, and in full production next year. I'm thinking that a PCIe card built with 4 of these will run about 25 watts, and produce anywhere from 2.5 to 3 GHashes/sec. Nice!
I see that mpfrank has rolled his own pipelined VHDL... http://forum.bitcoin.org/index.php?topic=22415.0
I'd like to try it, but I can't send him a message! Can someone let him know I'd like to try his code on a Kintex?
P.S. I work for Xilinx, so I can't ethically build or sell my own FPGA miner. But I want to help! Xilinx users can message me for help or advice!
For those who want to keep their VHDL/verilog private, I can execute a Xilinx NDA if you are nervous.
