Hi Nova following along with your thread. Are you located in the United States by chance?

Perhaps Nova can tell us exactly what FPGA IC costs 10,000 dollars. I have looked at the manufactures and I dont see any chip that 10K

You haven't looked hard enough.  Some of the latest gen FPGA Stratix V development boards by Altera are running about 9k to 12k each.

I've worked with their older boards.  There is another theoretical route he can try to take which uses some of the recent innovations with SRAM.  I have my own theories and I've mocked up some code but I don't have plans to buy a board to implement them.

For Scrypt it is not worth the time and money.  The total circulation and average daily transactions of LTC does not make it a good investment.  Anyone trying to implement a FGPA for Scrypt while LTC is under $5 is a scam (not directed at OP), or has not done the math.

Yes, he did mention the extra cost due to the nature of development boards. I honestly expect any device capable of decent scrypt hashing to be rather pricey, that's one of the main points. Wink

Yes I will tell you.  In fact that is one of the reasons I started this topic.  Anderl is right about the FPGA being an Altera Stratix.

I'm interested in hearing your SRAM idea as well as your other theories.

I'm from the USA.  Right now I'm in Ecuador, but the contract I was on ended and I'll be heading back in the next couple of weeks.
Specifically I reside in Phoenix AZ.

When LTC gets over $5.  Right now I'm find using ASICs for BTC and GPUs for LTC and scrypts.

But look into what is coming to market right now in FPGAs.

I can't say as I disagree with you there at all.  My only response to that would be it's pure research.
Xerox was researching GUI's back at a time when almost no one had a home computer. 
It didn't make financial sense either it was more or less a "hey cool look what we can do" sort of thing. 
That's really all this is intended to be.

I'm new to crypto currencies and I'm looking for a FPGA implementation too.

scrypt differs mostly because it uses an entirely new list so frequently.  
I think the big problem is that you can't unroll salsa mixing because of its recursive form. Thus you can't parallelize calculations as you can do with sha256. The only thing you can do is to have multiple instance of your 'cores' run in parallel. But I don't think Stratix have enough on-die ram (52 Mbit max) to overwhelm a pool as you said.

Quote
The shortcut is to have a multicore setup and a ton of on-die ram.
A dedicated prng core which does the setup and teardown for the second core.
I don't see the shorcut here. Are you thinking of a two stages pipeline with dual port ram in the middle ?

To conclude, I don't understand why you need funding for your idea because you can test everything with simulation. Altera provides a free web edition of their dev tools that don't allow you to target Stratix but you can target Cyclone V. You should be able to validate your idea with 12 Mb of on-die ram. Then you'll have tangible results to get funds for a dev board which are really expensive Tongue

That's a good idea.  I was unaware there was a free tool that wouldn't let me target the chip I'm planning to target.
Is there a compelling reason to choose Cyclone V over Stratix V?  Other than cost I mean?

Cyclones are a smaller, slower version of the Stratix lineup. The biggest Cyclone V is approximatively a third of the biggest Stratix V for LE count.
I suppose it should be enough to validate the shortcut.

Yes, I'm also finding out some exciting information in this thread and am trying to incorporate the new information in the writeup.
