I even tried to use Virtex slices which bitcoin the fpga max. Apologies that I don't have more to share at this time. You minerva also explore the Bitcoin Wiki:. It'd be pretty cool if specialized mining hardware hit the market. Hah, that Merrick1 board is 15 kilopounds. FPGA can be reprogrammed many times.

Mining is gonna be serious business. Log in or sign up in seconds. How fast is this likely to happen? Here's an opensource FPGA miner. But even correct inputs to the power estimating tools yields results that are not trustworthy although BL missed by a factor of 4? Be aware that Twitter, etc. As I mentioned elsewhere, what matters is clearly the cost of producing hashes.

Check out this thread. There will always be a premium for the Virtex. I hope to validate that claim soon on real HW. So the question is Bitcoin Forum January 31, Message 1 of 7 15, Views.

Then calculate the hashing rate using the clock frequency and number of parallel computation units. There would be some clock speed advantages, though. The real figure might be higher if there are architectural benefits in the Virtex-7 that you could take advantage of, or lower if there are other limiting factors, etc. All other things aside, maximum board size is probably limited by what your PCB manufacturer can handle.
Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type. Virtex 7 as bitcoin miner, how many gigahashes.
Message 1 of 7 15, Views. The beauty is that you can do all of this without having to purchase the chip first. Message 2 of 7 15, Views. Message 3 of 7 15, Views. You might be able to get a rough idea by doing the following: That's like all of deepbit on one machine. Check out this thread.
For people who don't know a ton about FPGA stuff, you can run a hash engine natively in hardware using a hew hundred gates at most for MD5, and run one hash per clock cycle, with a clock speed of Mhz. Apparently this guy is using a cluster of these now. Mining is gonna be serious business. Even a pool will have nothing on this. That's for MD5 - when I looked into it, commercial SHA which is what I believe Bitcoin work entails cores can do it in something like 50 clock cycles, which is substantially lower though I don't recall the exact numbers.
It's still worth looking into, particularly if you can bake ASICs for the purpose of mining and really scale it - but by that time you're looking at betting a not-insignificant farm on the fact that it will be useful at some point.
Should have taken computer science and been the first on this. But I haven't heard of anyone getting more than like mhashes on them yet. Hey yeah I actually googled it before I asked, but didn't understand. And there is no need for being dickish just because someone is stupid on the internet.
In simple words it's a piece of hardware that can adjust its design based on a description fed to it. So hardware that you can reprogram. In this context, it is a processing unit dedicated to hashing -- it can do only hashing, but does it very fast. FPGA can be reprogrammed many times. It cannot be reprogrammed once it's made. They use them for testing new codec firmware designs. Use of this site constitutes acceptance of our User Agreement and Privacy Policy. Log in or sign up in seconds.
