[ANN] Open Source FPGA Litecoin Miner

[kramble]

The main discussion is on the litecoin forum at https://forum.litecoin.net/index.php/topic,5162.0.html
But I think it may be of interest here too.

I hereby present my open source FPGA litecoin miner https://github.com/kramble/FPGA-Litecoin-Miner

Now don't get too excited. I only wrote it because I couldn't find one on the net, and its pretty crude as I'm an amateur at FPGAs. Its a direct port of scrypt.c using the on-chip FPGA RAM. Performance is quite pathetic at around 1kHash/sec per core (and I estimate 4 cores will fit on a LX150).

The initial version is compiled for a DE0-Nano (since that's what I have), but I have also done a version for the DE2-115 (simulated only).

I will need some help with a Xilinx LX150 port as I don't have a board to test on, and I don't have an LX150 Xilinx ISE licence (though I could obtain a 30 day trial). Though to be honest, its not really worth the effort since it'll only mine at a few kHash/sec.

My thanks to fpgaminer and the other guys who contributed to the open source fpga bitcoin miner project, on which my code is based.

Anyway, I hope its of some use. Feebdback and suggestions are welcome (the project is only one week old, but I thought I'd release it as soon as I had some working code). And yes, I know its abysmally slow

Thanks for sharing !

1kh/s per core ^^

1kh/s per core ^^

Yup, it wasn't a typo. One kilohash per second. But its early days yet, I'm hoping for some suggestions from the fpga pro's on how the code can be improved (or perhaps how its pointless to even try  )
