Hi!

We've tried v42 in -3C Xilinx FPGA and it is actually slower than the 200Mhz firmware.

N.G.Zhang, do you consider posting the code for the v42 firmware so we can fiddle with it?

Thank you.

We manufacture Bitcoin ASICs and Bitcoin mining equipment.

There's always room for improvements Smiley

Under development Modular UPGRADEABLE Miner (MUM). Looking for investors.
Changing one PCB with screwdriver and you have brand new miner in hand... Plug&Play, scalable from one module to thousands.

Hello
What happened to this project? is still alive? can I get dev-boards?, is some firmware already working with cgminer?

I just jumped into this and wanted to start playing with FPGA.
thanks

https://github.com/ngzhang/Icarus/blob/master/FPGA_project/Src/fpgaminer_top.ucf
# UCF for a Nexys2 500K board
NET "osc_clk" LOC = "J1";

# serial port receive & transmit
NET "RxD" LOC = "D1";
NET "TxD" LOC = "B1";

# TTL level serial port: ja3 = rxd, ja2 = txd
NET "extminer_txd<0>" LOC = "D22";
NET "extminer_rxd<0>" LOC = "B22";

Nice to see my serial clustering code (as originally developed on a Nexys2) is still alive and well Grin
