I bet a transparently developed AISC would go nuts on Kickstarter if BFL doesn't deliver soon...

I don't mind developing an ASIC mining chip, but there is no way I have the funds to get them made.  I'm sticking to my Spartan 6's for now.

I don't understand what the fuss is about
developing a SHA 256 ASIC and why many more have not already done it.
It takes millions to start making an ASIC. No matter if you design the chip, then you have to get the masks etcetc, and that means money, a lot of it.

Disagree it's not millions, but it is ~200k to get the foundry warmed up plus design charges. TSMC Shuttle service..

I been looking into this for about a week and it's been fun.
I think considering the money or bits or shit whatever it's worth a very close look funny we have our extra PC's here grinding away think they call it mining.
Another spot is www.opencores.org they also have SHA 256 .
I would go for an IP core not sure what one maybe the TSMC looked like the best speed, Multiplex < Spartan > (USB) or Ethernet.

We are also a Microchip design partner but they don't have anything with enough power.

The crypto core on opencores.org is FPGA based, your not going to break any banks there, but it's nothing a passing hobbiest can't manage either, more over, it's designed for a single SHA256 hash, you would have to write a script to pass every hash twice before moving on...

Your right FPGA is not going to do it, looked at that too slow and cost is high. I think the CAST or TSMC that runs at 500mbps?

I'm an ex Cadence design systems engineer, just thought i would post this here. I don't understand what the fuss is about

ASIC design IP for SHA 256

Good start is to download the chip estimate software developed by Cadence.
http://www.chipestimate.com/  lookup SHA 256

http://www.chipestimate.com/ip.php?256-bit+SHA+Cryptoprocessor+Core&id=14006
This looked good the TSMC core is also available that many are working with.
We use Cadence and Altium electronic CAD, here ready for hire!!!

The problem isn't the cores, almost any electrical design hobbiest can design a SHA256(SHA256(x)) core with the help of google and some opensource IPs, its the massive overhead that is the hurdle.  Not many here have the 6-figure bank account to make a mass order if ASICs, nor the man power to put all of them to work.

Hell, if you want to find the capitol, and are willing to sell singles, I'll buy a few, but anything beyond that takes more than most have.

Sorry missed that comment typing at the same time, agree it is expensive designing new electronics. I think that there is also a lot of BS in it and scammers it's bad for Bitcoin and the mums and dads that want a simple solution.
But the underlying code, idea looks great or fantasy!! If you have soem Hardware ideas please post I'II have a look, right no just need a block diagram. I don't think that is so hard though.
