The scripts would need modifying though some comments on one of bitcoin other threads here EDIT: By the way, how many slices did you calculate that the Spartan algo ohio need?

Eventually, computers were replaced by FPGAs I don't find multitasking easy. Kintex-7 would be the better choice. Escrow is fast, safe and easy to use! The port widths are mismatched in the mentioned assignment. The model for the simple one is Spartan 3E The model for the advanced one is Virtex5. At least that is what you can get with this thing:
PS There should be some info on flashing spartan non-volatile minerva roms in the DE2 user manual. More specifically, Bitmain has announced the Antminer A3, fpga is designed fpga for the Blake 2b algorithm. The change to alt coins has already happened with the migration of GPU miners from Bitcoin to Litecoin and others. Bitcoin I start mining then? Additional clearance to allow ohio larger heatsinks. Bitcoin FPGAs would work, but it spartan be difficult to find a place ohio the hash chain to break up the design without drastically minerva the overall hashrate.

I can't see the board using cgminer-fpgaonly sees usb devices, no suitable miners. I saw you had some scripts included. Then I get this error:. That just causes more errors. I guess what I'm saying is: Yeah, I forgot to include quite a lot of background info which came from the original bitcoin fpgaminer project its well worth taking a look at.
I'm not sure what you need to do to fix your quartus installation have a word with your lab tutors , but you will definitely need quartus-stp. My board is a DE0-Nano quite a bit smaller then the DE, though I am told it works fine on this board , and I just installed the full Quartus suite version 10, since that was what came on the DVD-Rom If you can use your own laptop, just download and install the latest version.
Assuming you're running windows you just need to cd to scripts and run program. Then you run mine. On linux I guess you just run the quartus-stp commands directly from the shell just one-liners, see the. I don't think it will talk directly to a DE2 board either. PS There should be some info on flashing the non-volatile configuration roms in the DE2 user manual.
Its done from within the Quartus programmer GUI, but I would not recommend it if this is lab gear, best to leave it alone and upload as you need to. Well, the lab is Linux, but I'm fairly certain I have all of those. If that's not possible, I'll try your other suggestion. As for using a mining program directly, is it possible to use any existing programs as far as you know? Also, one thing I've been wondering from the beginning and would probably be more clear once I got an actual board working is: Where does the check for the valid hash happen?
None of the existing programs support litecoin FPGA this is bleeding edge! The tcl scripts are fairly reliable though, if used with a local stratum proxy server just get it working on getwork first before trying this. Data transfer is minimal. The hash check is on the fpga, and is sent directly to the mining pool which ill accept or reject as it sees fit the stratum proxy is a little more intelligent and checks the hash before submitting it But that's just because it was the way the bitcoin miner did it, the actual data requirements are very light as I said earlier.
Response is quick 'cos I'm currently online: Is it just for simplicity's sake? Once again, thanks for the quick responses. On Sep 5, 2: I use Serial and add a cheap cp adapter on some spare io pins to get my comms to the software as it the easiest to do and lots of examples to base my code on.
As Blue said, its just developers working with what was to hand. The Altera boards often only have the jtag usb-blaster , so that's what got used. Some of the xilinx dev boards have usb serial, so that got used. And I'll agree that getting to grips with the bitcoin miner is probably easier there is a whole lot more written in the forums support-wise, though its gone very quiet now that bitcoin difficulty has gone stratospheric. So it boils down to it mostly being a convenient hack, that's cool.
I'm wondering if this would work with a larger number of boards like how the Bitcoin boards do with USB. If you could daisy-chain the JTAGs to get a nice cluster going. It'd be limited by size, but it could work, right? Yeah, it's a shame about Bitcoin. How long do you think Litecoin has until there's that sort of change in difficulty? Or do you think the nature of it will keep that from happening? On Thu, Sep 12, at 5: I had to buy a real altera cable actually a Terasic, and yes, it costs 50 bucks.
I'm not able to do it. The altera jtag drivers support multiple devices on multiple boards. The scripts would need modifying though some comments on one of the other threads here EDIT: Performance would be an issue as its really only meant for debugging, not for production use.
You'd be better off just daisy chaining the boards no need for adapters, though you might want to use opto-isolators if you're worried about having all your eggs in one long chain. Then either use jtag or a rs adapter as suggested by Blue I did some work on this in my DE0-Nano github, but only ever chained a couple of boards bit of a mixed bag of two DE0-Nano's and a pair of homebrew boards, one each altera and xilinx.
On the difficulty, there was a big spike a week or so back, probably a huge GPU farm switching from bitcoin to litecoin, but I don't see it going stratospheric. ASIC's just won't give the huge performance leap for scrypt that they did on shad.
Not impossible, but performance will not be that much above the current GPU level. The change to alt coins has already happened with the migration of GPU miners from Bitcoin to Litecoin and others. Makes it so much easier to tweak the clock speed. So is it [fpga mining] not profitable because we haven't gotten it tight enough to fit loads of cores per board, or is it because the market got saturated with a player that's too big compared to the average miner?
FPGA will never be profitable for litecoin. This project is more about finding a use for old bitcoin mining kit rather than creating new gear. Still Jasinlee has a project on these lines, and good luck to him, he may prove me wrong. Just got lucky I think as its a bit on the tricksy side. I mean once the designs have been tweaked. I guess there's nothing to be done about botnets considering their masters don't need to worry about hardware costs or mining difficulty.
On Sep 12, 5: Yeah, the FPGA has the advantage electricity-consumption wise. There really is only a fixed pot of LTC to be mined per day, so when the GPU farms come over, we have the same race to the bottom as bitcoin but without the disruptive change that ASICs made.
As I've been nagging on bitcointalk, its gold-rush territory out there, and only the shovel sellers are going to make any money. Anyway, this is getting somewhat off-topic for this thread really ought to take it to the litecoin forum , and its getting on for my bedtime. The issue was that I was using Windows and obviously didn't even consider trying command line arguments So then I tried: I forget that Windows isn't inadequate when it comes to running things.
In this video I take a look at Bitcoin mining hardware. I demonstrate these in the Bitminter mining client and measure the power with a Below are statistics about the Bitcoin Mining performance of ASIC hardware and only includes specialized equipment that has been shipped.
This however, quickly accelerated through the ever evolving and creative use of more advanced pieces of hardware. The progression of mining in Bitcoin went as follows: While most of these were based o What are the primary differences and, more importantly to my purposes, how do those differences play out for bitcoin mining purposes?
Sorry to burst your bubble in the first sentence. Maybe you think that you can use your hot Digital Design skills to program your sweet Xilinx Spartan 6 development board to make you tens of thousands of dollars.
Well get that idea out of your head In the world of cryptocurrency mining, ASIC hardware is in high demand. Although many people would associate this type of hardware with Bitcoin or Litecoin mining, there are devices suited for other currencies as well. More specifically, Bitmain has announced the Antminer A3, which is designed specifically for the Blake 2b algorithm. So far, there is only one major currency which uses this algorithm.
Fans of Siacoin will be pleased to hear that this Thu, 18 Jan Siacoin SC is weathering the current cryptocurrency market nosedive pretty well today. Compared to the rest of the highest-net-worth coins, that's a very upbeat situation. Most of the top-ranked cryptocurrency options are sinking into the double digits.
