I have my own Scrypt code for Xilinx FPGA and a pluggable rack system, that takes 10 boards, I had to mux them as 8+2 hot spares.(yep sometimes they drop in & out of service randomly)
Unfortunately...
Performance is shite...... insofar as comparison to high-end CPU or GPUs.
Who knows if I can get an improvement but it is going to be very hard to beat the GPU thrughput Vrs cost.
Interesting. Thanks for the detailed post, especially the last part where you share your results.
This is good news as far as I am concerned, the whole point of Litecoin using Scrypt was so it would be difficult for specialised hardware to have a massive performance edge.
