Black Arrow 28nm 100Ghash Bitcoin ASIC from $0.49/GH/s

[Cheshyr]

Reading through the news posts on their websites, it sounds like they had to completely redesign the asic to go from 64 cores to 99 cores, and adjust the closck frequencies accordingly.  Their delivery deadlines for batch 1 seem to be late april early may.

Frankly, that's all the information I need right now.  the rest is just noise until they have something they're comfortable sharing.

Where do you see that batch1 delivery has changed? Apr/May is for batch 2. "This is a PRE-ORDER (Batch 2), available for dispatch at end of April 2014"
 Yes they added more cores but where does it say they had to do a "complete redesign"?  

Their January 3rd new post implied batch 1 was May 1st.  Perhaps I misunderstood.  http://www.blackarrowsoftware.com/store/batch-1-closed.html

All the unit does is receive work and distribute it to the various unrolled cores.  Adding more cores requires scaling out the control system to address them, and the health monitoring systems to watch them.  That pretty much touches everything on the chip.  Maybe redesign was a poor choice of words; they had to edit, modify, and refine most major components of their design.

I'm still very excited for this chip, and I'm glad they're getting it right instead of rushing it out the door.  

edit:  They also mentioned in their next news post why they were making the changes.  http://www.blackarrowsoftware.com/store/minion-c-driver-is-now-available.html

Silence is not a good operating strategy, IMHO.

If you bothered to read this thread you would already know the BA forums are at http://ecointalk.net/ not here.

Secondly, there is no point posting updates unless something has actually changed, it's not like a newspaper where you have daily space to fill.

kindly point me to the thread where they provide us with information on what is going on wrt tapeout. thanks.  

what? can't do that?  Why not?  If you bothered to read this thread you would know they have been silent on tapeout.

You mean they can't tell us what they have done since early Jan and where they are at?  As I said, their right to do that but not a good business strategy for the future.

One of two things has happened since their last update.

1. They taped-out and have a chance to still deliver on time.
2. They missed the tape-out date and thus cannot deliver on time.

99% chance #2 has happened.

True enough, however if left to their own speculation for too long, this board seems to go full retard FAST...

This from the asicminer thread:

*If* they taped-out on Jan 20, and the fab started making the mask straight away it wouldn't be finished until late February at the earliest assuming that the fab will shut down for a week at the beginning of February. Then they have to actually make the wafers, slice them, package them, bump them and test them. If all that goes as fast as practically possible, and the tests results are good enough, then they can produce the chips in volume. I think with everything going about as well as could be expected they might have chips in volume by early April, not earlier. Then they've got to put them on PCBs and do final packaging.

If they have working miners in volume by the end of April they will have excelled themselves. Anyone who hopes for significantly sooner is going to be disappointed.

Now, see why I'm worried?

After dealing with BFL,how late can they be    I've allowed for 1 month delay,maybe 6 weeks..........but,even 8 weeks won't make me cringe.

I was first day order with BFL & waited over a year for my 30GH,so I ain't sweatin nuttin 

[tempestb]

Wait.  There is nothing you can do otherwise.

[Stedsm]

+1   couldn't have said it better!

havent been following the development, but last i checked i remember seeing end of feb as the delivery date.

did they lie?

Did Feb. end yet?

This exactly.  Getting an update would be nice but they aren't late.

Well, if they surprise us, then the silence leads to that dramatic effect (rationalizing here)

And if they don't, well the trust on their silence, and future projects, is broken.

This "rationalizing" does not make much sense. They want to sell batch 2 as fast as they can so if they had anything positive to report - they'd be banging that drum, I assure you. The fact that they are not doing it, well I'll let you rationalize some more but I really doubt they are going for the dramatic effect here...

[nosferatujeff]

You are correct... however I have no buttons to push to get real information.
