How many gates BFL and Avalon used for each core?

Thanks

42

42 ? were they golden gates or pearly gates? :)
come on I am not stupid

Why do you keep asking these simple design oriented guestions if you claim to have very potent engineers working on designing an ASIC for you? These questions are not something a credible company needs to ask from a internet forum.

This is not just an Internet forum, here are a lot of smart people. There are many SHA core implementations and Avalon said that they looked into buying SHA core IP but theirs was better so they decided not to. There aren't any engineers that specialize (made more than one) in ASIC design for bitcoin, it's too new. No one knows everything and I am just crowd sourcing knowledge to make sure that I make most efficient and high performance product. That is why I am rechecking some engineering against the crowd.

Crowd sourced engineering sounds like a recipe for disaster.

I think it's more like over 9000.

42 is the answer to everything.. :)

+1 definitely 42

In no way am I doing crowd sourced engineering, I am just checking some things.

9,000 ? do you have reference ?

Not 9000, over 9000.

awesome troll thread.

watching! :D

Avalon used 42.
BFL uses zero.

The BFL miners have infinite performance, they have mined millions of USD worth of payments while using zero electricity.

Avalon's performance is a bit less impressive but a bit more tangible.

You are likely to get not answer due to 1) nobody outside of those companies know the answer 2) those companies aren't likely going to reveal that answer 3) you come off as foolish and uneducated. Regardless of what financial resources you have, you appear to be using this forum in an attempt to understand how one goes about building an ASIC that hashes. This does not bode well for your endeavor, if it is anything more than a scam. Perhaps instead you should configure a FPGA to understand the process and then proceed from there? There are a few FPGA designs scattered across the web to help you get started.

If you knew about ASIC design you wouldn't have made the comment #3, thanks for the first 2. So please don't troll. And I asked the question because they may have talked about it publicly that I didn't came across yet.

I will agree that I do not posses the skill set to develop an ASIC. Given past experiences with VHDL I suspect I could at least create a design that that implements BTC's hashing algorithm but I would have no clue how to make the jump from a wad of code to a hardware implementation of my design. From what I understand, a fully unrolled core is simpler to design so I'd go with that to start. At the end of the day I could give you a gate count for my implementation but I imagine someone like ngzhang would know more tricks to optimize the design by removing redundant components and increase the maximum frequency of the design. At the end of the day that's why he works and builds hardware while I tinker with higher level languages.

I do not troll. If I trolled I'd have given you numbers that sounded believable but were full of crap  ;)

I think reasonable estimate could be made by finding out the size of chip and then finding some chip with know gate density or gate count made with similar technology.

And I don't have idea of either one ;D

You're new to this Internet thing, aren't you?

The size of chip that Max wants to gate is 20nm for this fall/winter delivery.

21,000,000 max.
