Musing on a new ASIC for Bitcoin Mining

[rtt6942]

I've been looking at the Bitcoin community for about two weeks now.  This started as my company has received numerous requests for an FPGA or ASIC solution for bitcoin mining.

   My company is a small design house that primarily designs ASICs, but also some FPGA and PCB level products.  We have even done a fair amount of small quantity production.  All of our engineers have 20 to 30 years of experience in design and development and we have collectively, successfully completed over 40 ASICs and many FPGAs and system level products.  Personally, I am a former VP of engineering for a supercomputer company and an accomplished processor architect.

   So just for kicks and chuckles I coded up my own SHA256 engine and built a bitcoin miner.  My first effort was to push the design through the Xilinx design tools and see where we stand.  I decided to only use the main fabric of the FPGA (no DSP or Block RAM) so that the design will easily translate into an ASIC later.  Here are my results:

   Xilinx Kintex 7   XC7K160-1   400 MH/s  at 10.12 Watts
   Xilinx Kintex 7   XC7K160-3   500 MH/s  at   9.81 Watts

   Those power numbers suggest that I could push the -3 version faster.

   Interesting but it seems that the community needs ASICs.  So we are doing a trial place and route of this verilog design in our ASIC tools to see where we are with an ASIC.

I think I speak for many when I say it'd be great to see another ASIC company in the market, especially one that is actually able to ship products.

If you decide to produce this I would certainly like to hear more -- and probably buy a few miners, depending on price of course.

[rtt6942]

Shipping product is only really a function of planning and experience.

Too soon to talk of price but this looks like a fairly small chip, to us at least.  So the manufacturing cost should be very low.

[Surprise]

If you can actually produce and ship an ASIC you'll have a goldmine, but considering how many people promise ASICs and how few deliver don't expect anyone to trust you until you've put working machines in the hands of trusted people in the community.

[Endlessa]

If you do the following:

1) Make a product
2) Sell it for a price that will allow people to profit after 30 days (don't do what Avalon and AsicMiner did, which is capitalize of the fear of not owning one)
3) deliver it too some bloggers
4) open you manufacturing facility to be viewable (photos, webcams, etc)
5) have a supply line that can ship a product to a user in < 30 days
6) be ready for a flood orders

then you sir will have a crazy cash machine on your hands. . ..in the end with bitmining, it's the hardware makers that will make "bank"

If you can prove you have a working product, send it to some bloggers to get some more PR, allow miners that live close to you to come see the ASICs in person, provide REALISTIC shipping estimates, and competitive prices, you could make a ton of money. The smaller your shipping time, the more money you'll make.

Would also love to hear more

Very cool!  Sounds like you guys have a lot of expertise in the area which could make you competitive quickly.  Not knowing much about hardware architecture I wonder how this would be scaled to higher speeds.  You mention you mostly do small quantity production so you'd probably be thinking of making more powerful more expensive rigs, as opposed to cheaper high volume ~500MH/s USB sticks?  Also, are you guys in a position to make the whole product or do you just do integrated circuits?

[jgivg]

Sounds great. In case you ever create them, will this post count as a preorder and put me in a good spot to make an early order? 

[rtt6942]

It seems that this whole community has been bitten by poor performance from so called ASIC suppliers.  I does make me pause to consider if I want to get into this but the potential is intriguing.  We certainly know how to build ASICs and assemble them onto boards and manufacture them.  We are also hooked up with a number of Contract Manufacturers (CMs) who could manufacture in volume and then build and ship to order.

So I'm going to look into this further and see what happens! 

Our trial place and route is nearly done so will post the results shortly!

[rtt6942]

Well trial place and route looks good!!

Timing comes in around 711ps so I'll fudge that to 800ps.  So we should get a clock rate of 1.25 GHz.  So our core will run at 1.25 GH/s.

So now we will investigate power and area to find the optimal number of cores we can package in a single die (chip)!

I'd like it to be 8 so we have a 10 GH/s chip!  100 chips 1 TH/s

[sgh858]

It's great new if it's actually true, consider people waiting from BFL for almost one year already with nothing other than "testing", "shipping in two weeks".

I would like to be in your pre-order list too. Please add me.

[sgh858]

BTW, please forget about the power consumption optimization. We need the product first, be it 100w or 500w or whatever. You just need to make the first generation of ASIC miner, sell, ship to us.

Power optimization can be done later in the 2nd gen.

In bitcoin mining, time is truly the money.

[Astrophysical]

add me to the pre-order list as well 

power optimization is truly a secondary concern to most

[bitcoinminerz]

This is really interesting, I'll certainly be keeping an eye on this.

[paulin]

I am also looking for ASIC miner

[Kiders]

sign me up for one asap

[evilscoop]

if you are working on this, can I suggest you also investigate making scrypt asics and or fpga's too...

you really will get a flood of orders then

[rtt6942]

Well I'm encouraged by the interest even if this still in the Newbie area!

The power optimization step is so we can judge how many cores to put on a single chip.  You wouldn't want the thing melting after all!  This design is mostly flip-flops which use most of the power in a chip so we need to careful here to get it right!

As far as pre-orders go I think we are too early, but assuming this thread persists then I guess an order is established as long as they pay up when required.  At least it can be an order for rights of refusal.
