This is a demo of an FPGA miner for Decred using the Xilinx Spartan-6 LX9 chip. It's a very simple design that doesn't include any optimizations or a PLL and mines at 4Mh/s using a 50mhz clock. It is for demonstration purposes only. You won't be able to mine any coins using an LX9 fpga, you'll need much larger fpga boards.
