Title: How many cores on the avalon asic chip
Post by: BitMonkey on April 02, 2013, 12:09:23 AM
Im trying to understand how these things work.

We got 80 chips per module, each module producing at least 20 g/hash
so each chip is 250 mh/s

250,000,000 hashes per second

And a hash is 512 bytes (Right?)

Im getting 128 Gbit per second per chip in throughput (term?)

This seems like a lot

Am i doing something way wrong?

Fail.......

send me your Avalon and I will send you a maths book and a link to the bitcoin WIKI

I dont have an avalon.
I would like an explanation as to what simple thing I am overlooking.

Each chip has one core that runs at 250 to 300Mhz, 1 hash per hz.

No! To get through the SHA256 pipeline you need at least 66 clock-cycles! And this is excluding all other delays, loading/extracting the data etc... Unless you know something I don't!

EDIT: Yep, I obviously didn't know better...

I don't think you know how pipelining works.

Yep, you're right. :(  I just realized after having read THIS (https://bitcointalk.org/index.php?topic=44891.0;all) excellent thread...

Do the ASIC chips only have a single core which runs at 300MHz?

I don't know. You should probably post a thread about it.
