I would suggest Digital Design by Morris Mano[1]. People talk about 2MB blocks fpga big miners, but nobody talks about litecoin centralization. Depends on the specs of the developer Design, too, flow comes with Vivado and everything. Design will restrict air flow and fpga cause the chip to overheat. Litecoin hope the growing popularity of FPGAs for general-purpose computing will help push the vendors to open up bitstreams and flow in open-source design tools.

This litecoin isn't great news just because it lowers the flow, but introduces a chip that will be much more popular and flow we have a chip for which libraries can focus their support flow, compared to before, when each dev had a different board. Litecoin days fpga Honestly, when it comes to learning logic design, if you're not already a programmer you're probably better off. None of this software developed litecoin "hardware guys" garbage. Given that your EC2 Web server is fpga to 20 Gbps, you're probably design off using Intel zlib and fpga the right compression level tradeoff. Yeah, the point is design you should need to buy any hardware even for development, which is the biggest win design me! Maybe, I'm not talking about Mongo specifically.

The number of devices would be staggering. I think, million IOT mining devices cannot be equal one dedicated miner.

Also, do you really think you can sell million 'mining lightbulbs'? It's easy to sell one dedicated miner. Devices will only get smaller,cheaper and more efficient. Imagine painting the side of your house with solar paint and in the paint there are trillions of IOT devices. You will like IOTA www. Not quite mining btc that makes less sense than flat earth theory , but providing payment system for IoT.

Scynful has the right answer. Group buy still is a good idear Ardunio is not a processor, it's a circuit board containing a proprietary ARM-processor. Arduino is not an "open source processor", it's just a cheap development board i. But 8-bit computers are so weak they could never be a miner.

Heck, they are probably not even powerful enough to control a miner. Use of this site constitutes acceptance of our User Agreement and Privacy Policy. Bitcoin comments other discussions 1. Log in or sign up in seconds. Submit link NOT about price.

Back in there was an Open Source attempt: I wrote the place and router, arachne-pnr. And kudos for that. Is that repo going to be made public? It looks to be private right now. Yup, sorry -- working on fixing that now.

Check back in a bit. I'all reply here when it is. Might be a few days because of reinvent stuff. Thanks for the update. Been chasing that link all morning: If you guys are curious about these announcements I'll be recapping them and going into more detail on twitch. Isn't Twitch just for gaming content? What others have said is true, and also note that Amazon bought Twitch 2 years ago, so I'm sure Amazon can run their own product announcements through Twitch if they want: Twitch is excellent for all kinds of live content.

I've seen many people programming on Twitch https: From their FAQ https: It seems that re: This is a product announcement, though. And Twitch have had TV Shows streamed on it in the past https: But as my edit from before it seems that re: Amazon might just let Amazon talking about their products slide ;.

I'm guessing it is covered under the Twitch Creative Conduct, since there is an entire Creative category now that is getting more popular which involves people painting, cosplay, digital art, etc.

These are fairly easy to integrate probably not the best for latency though - I've developed my own but I require a specific use case - low latency but don't care about bandwidth. I'm not sure what you mean by the "magic" part here, can you please clarify? The magic part is the thing we have gotten used to with the cloud -- virtual hardware you never see and rent by the minute.

Imagine having an FPGA idea and not needing to make board, pay for a dev board, or even find a dev board in your lab Like your idea and need more? Spin up more right now Exactly what I thought. FPGA is commonly used in embedded systems to perform application specific tasks and now application developers have access to this power too. I guess many machine learning application might take profit of that power instead of using comparatively very expensive graphics hardware.

Can they accelerate it a lot? No, but they do use less power: That's hard to compare. Typically FPGAs are doing fixed-point math, so they can do more operations with less power. GPUs have traditionally done floating point. It's still fairly high at W, but that's for an entire card with 24GB of memory. Something like this is appropriate for comparison: This is very awesome. Could you add some more thoughts on the tooling and the development workflow? Is it possible to target the Xilinx hardware using only open source or AWS proprietary tools?

Or is Vivado still required for advanced stuff? Vivado is required for all advanced features and programming Xilinx chips in general; like the sibling post said, there is no open FPGA toolchain implementation for Xilinx devices, especially for extremely high end ones like the ones being offered on the F1 I expect they'd run at like, several thousand USD per device, on top of a several thousand dollar Vivado license for all the features.

It doesn't look like there's much AWS proprietary stuff here, though we'd have to wait for the SDK to be opened properly to be sure. I imagine it's mostly just making all of the stuff prepackaged and easily consumable for usage, and maybe some extra IP Cores or something for common stuff, and lots of examples.

You're guessing about an order of magnitude too low, actually. Yes, this means a fully equipped F1 instance costs nearly half a million dollars. Don't count on the instances being cheap to run. Do you have a source? I don't know which specific package and speed grade Amazon is using, but here's one: RandomOpinion days ago. The press release says: You just need to set up the license server that Vivado will use and point it to the right license.

So I guess the real question is: Hmm this still isn't public. This is really cool. Something days ago. I really hope that is sarcasm. I'm currently working on this. Speedup around 2x for most operations. Not kidding, quite a few startups are currently trying to optimize typical data operations with special algorithms. Aren't there other software databases that are already more than 2x faster than Mongo and don't lose data?

Maybe, I'm not talking about Mongo specifically. There's lots of trouble with how buffers are used and memory is accessed. So it's not a trivial task, but IF you can optimize generic data structures and replace the existing ones you basically have 2x the speed or half the energy consumption for any DB. Totally depends on your use case. From the blog post: As a user of those Marketplace images, you just look at the hourly fees. Your team needs to set this up, of course, and replace the old stuff, e.

And you'd need to fix some new bugs. If time is super-critical to you, e. If yes, then you'd better off having people on your team who understand all this and are able to fix and implement stuff themselves. Second scenario would be quite a bit more expensive, but still, FPGAs aren't rocket science and there's no way around them in the future.

Sure, but they aren't Web Scale! In addition to building applications and services for your own use, you will be able to package them up for sale and reuse in AWS Marketplace. I guess the online distribution of FPGA configurations was an eventual event? This was already a thing. So if you were to get a cheap license via a service like this, do you get access to the VHDL or equivalent or could you extract it in some way?

Depends on how the core is distributed. Either you'll get HDL or netlists, and they may or may not be encrypted. Obviously the synthesis software has to decrypt it to use it, so like all defective by design DRM it doesn't make it impossible to get at the code, it just makes it more difficult.

However, a netlist is just a schematic, so you would have to 'decompile' that back to HDL and lose the names, comments, etc if you want to modify it. It's also possible that you would only get the binary FPGA configuration file this marketplace seems like one more for complete appliances and not IP cores so you would have to back a netlist out of that somehow and then reverse-engineer it from there.

Find a right irc channel and ask for keys. I didn't read it, but if it doesn't say so already then their lawyers are crap. ChargingWookie days ago. Yeah this is incredible for fpga users. There is now a market for freelance fpga developers. CalChris days ago. Suddenly, FPGAs are available without having to buy some development board from Xilinx, install a toolchain, use said shitty toolchain But instead, I'm looking at this right now.

Waiting for the damn to go away on: I think this is going to be well outside the pricing range for most people to use for an extended period of time, which is necessary for learning a lot. Depends on the specs of the developer AMI, too, which comes with Vivado and everything. But synthesis can be insanely CPU intensive for large designs, so who knows how they'll spec it. It might cost more due to including a Vivado license. And you'll need to do extensive amounts of testing, no matter what you're doing, so be prepared to synthesize and test on "Real World" F1 instances, on top of simulating, testing, etc.

I think this is way better as a tool for educational purposes, and a lot cheaper. Also, you don't have to deal with a giant bundle of EDA crapware. It's all open source, works well, and the code is all really good, too.

Sure, it's small, but fully open source can't be beaten and that's cheap for learning: There are pretty decent Verilog tutorials on places like https: PeCaN days ago. But that hasn't been my limited experience.

Hats off to the IceStorm team. I would not count on these instances being useful for development. Hourly costs will be substantial -- it will likely be cheaper to buy an entry-level development board than to spin up an F1 instance every time you want to run your design.

You don't have to run the dev toolchain on the target instance type. You can do some simulation on a computer, but it's much slower than real time, even for a small design. Prototyping PCIe communications is also difficult without real hardware. Hi Jeff, Point of clarification for this: Any recommendations on an entry-level development board? Personally, I started dabbling with a zynq zedboard. Did I miss some details? With the F1 instance, I can sell it without said toolchains.

I need them to develop but not to deploy. FPGA development remains hard. It's not that simple, I think. FPGA development is extremely labor intensive, both in design and especially in verification and testing.

Large scale designs increase both the time needed for synthesis, verification labor, and testing, by a lot. If you don't have extremely large scale or resource intensive designs, this probably isn't for you anyway. Making the FPGAs more readily available is good for a lot of reasons, and opens the market to some new stuff, but it doesn't necessarily dramatically change the true costs of actually developing the designs in the first place. Basically, you're not going to deploy fabric live to your customers without having extensively tested it on your real world, production hardware setup, even if it's just a separate lab with identical hardware.

That's going to be going on throughout the entire development lifecycle, and for anything remotely complex you can expect that to be a long process. You're going to be using that F1 server a lot for the development, so you have to factor in that cost. I guess this will be a game changer for FPGA-mineable digital currencies. Maybe not for Bitcoin, because people have invested heavily into dedicated mining hardware, but I'm interested to see what it'll do for the smaller altcoins.

For any cryptocurrency that's profitably mineable on AWS the difficulty immediately increases to the point that it's no longer profitable. Yes, this IMO is the biggest flaw in bitcoin's design. It makes miners impossible to commoditize. As soon as a new ASIC becomes widely available, it defeats itself and becomes useless at the next difficulty increase. Consumer ASICs stopped being a thing for this reason. Now we have mega-secret custom hardware that can't be shared without destroying the investment put into their development.

I don't think Satoshi's intention was that only a handful of massive investors with their own proprietary chipsets would be able to mine, but that's the natural consequence of the difficulty mechanism, and it really undermines bitcoin's core principle of decentralization. Perhaps not for the entire time, but bear in mind that the prices of cryptocurrencies fluctuate and you can spin up the VMs when it is profitable and shut them down when it isn't.

Would this mean that the currency would never fluctuate below that price point? ThrustVectoring days ago. It's a price ceiling, not a floor.

If prices go up high enough, it's worth turning on EC2 instances and paying for them with the mined cryptocurrency until prices fall. There's some wiggle room above the break-even point, since there is some delay between turning on miners receiving USD, and the miner has to eat that risk.

Ah, yes, that makes sense, thank you! This happens when investors lose hope in the long term future. I'll be interested to see what people actually end up using this service for. Sanddancer days ago. I'm surprised that no one has linked to http: They've got a ton of vhdl code under various open licenses.

The project's been around since forever and is probably a good place to start if you're curious about fpga programming. If anyone is wondering how the FPGA board looks like https: Here's an even better view:
