Title: Practical System for FPGA Litecoin Mining? Post by: crazy_rabbit on December 18, 2012, 02:07:14 PM Take a look:
http://www.bunniestudios.com/blog/?p=2686 It's a 'open hardware' laptop project with a Spartan 6 built in. But it also has an ARM processor and can have plenty of ram. The ARM is also directly connected to the FPGA- the builder even mentions mining Bitcoin. Perhaps this would be perfect for Litecoin? Title: Re: Practical System for FPGA Litecoin Mining? Post by: Photon939 on December 18, 2012, 03:34:04 PM I saw this yesterday, it's a neat project but I see two major problems for litecoin:
There's no memory directly accessible to the FPGA and the price for this board will be "not cheap" Title: Re: Practical System for FPGA Litecoin Mining?

Besides, if it's NEON optimized, I don't see what's stopping it to being as fast as a good processor, and if the price is cheap then you could stock up on some and mine LTC decently.

The quadcore A9s only gets between 2-4kh/s if I remember right, the NEON miner is energy efficient (~2x more than video cards) because it uses the on-die L2 cache but the chips are so expensive that it's pointless. Also you might hit that efficiency if you way undervolt GPUs too, I haven't really tried but I wouldn't be surprised. |
