Hi all,

Sorry I haven't had time to read this thread, I have been working like nuts trying to deliver as promised.

The Keccak-24core/708MHz (17GH/s) bitstream burns 306A and will run on an unmodified VCU1525 for approximately 10 seconds.  To run it continuously requires extensive modifications as described here:

The Keccak bitstream is now posted live on the website:

Also, there is an interesting table where I calculated how many FPGA's each algorithm can support:

So based on the current market, FPGA-friendly algorithms can support 25,000 FPGA's.
