wondering if this BFL Single FGPAs can mine PPcoins?

Maybe I'm not getting upset because I've been through this before with the FPGA's. Just keep mining with your video cards and try to enjoy the holidays.

is this for sure for all upgrades?
TIA

Tried a windows version of 2.8.2 on 1 x CM1 + 1 x BFL Single on Win7 x64.
It starts as usual, attaches to stratum and makes a look of hard working, but never makes any shares, just takes Icarus Re-estimations periodically.
Ran it for 5 minutes - U is still 0, no shares.

O_o

Got back to 2.7.6 through mining proxy - it works well as usual.

This is a tempting investment.


Though, it's unsettling to know that after share principle repayment 50% of return goes to a small group of individuals that is Bitfountain.

Conservatively, IMO, Bitfountain's take might be $40,000+ for the first month after funding repayment.  Definitely a sweet deal for Bitfountain.


Bitfountain will always own a minimum of 50% of their self-run hashing capacity.  Makes me nervous the same way Vladimir's plans did.

I am 100.5% sure that's a typo ASICs are a 2012 topic.

They are raising money to start production through GLBSE and private share placements

There is now. But it's not named as CAD drawing, but IC layout.

The first picture is the IC layout of the whole chip after P&R. The big cyan bar in the bottom center is the pins of the chip. Purple bars above and below the chip, as well as the light blue bars in the left and the right of the chip, are all power pads. The small rectangle in the bottom left is the blackbox of PLL IP module. The rest parts are real hashing units doing the actual job of erupting blocks.



The second picture is a magnified local part of the hashing unit. It's harder to tell which part is which in this picture, but it feels very nice for ourselves to see how our logic design turns out physical.

Thanks. Yes, basically the more ASICs are produced, the lower the cost per chip becomes.


In fact, the margin cost per chip is less than $0.8 a piece, that is hopefully $0.8 per GH/s. Of course, if we consider the cost of heat sinks, fans, PCBs, power supplies, and the disperse of the initial NRE cost into each GH/s, it will be significantly higher, but still within a single digit dollars per GH/s.


If only considering the whole production cost, it is easy to achieve more than 100MH/s : 1$. The actual market price is another story of course.

ASIC is a custom chip, they are a built to order to a very specific spec (for bitcoin mining) and in large amounts to be cost effective, usually over 10,000, however really large orders of 200k make it far more cost effective, but larger upfront costs. It's static, unlike a FPGA, so they can't upgrade it once made, it's why it costs so much generally.
So ASIC can be quiet cheap when you compare them per individual chip price, but it's a big start up cost for the designer. FPGA's are more expensive individually, but you can do more with them, and on a small scale the cost is easier to pass on without hurting their accounts.


Price could be cheaper than what BFL is offering their ASIC devices at since their first designs are on a older, but more cost efficient for them process, while BFL opted for one over 3x more expensive by the speculation circulating their numbers they saying it will do.
It however is far more efficient hash/s per watt. I'd estimate the Block Erupter chips (just the chip) will only be $5-15 a piece, but that isn't all that goes into them and also they have their own profit margins to worry about, so it won't be that cheap. But below $100 would be reasonable, since we know it's less expensive to make them.



FPGA's and ASIC will play a bigger part in bitcoin by next year, personally I do believe the use of GPU's is going to start fading, just like it did for CPU's. It's a matter of time, but it will eventually happen, some are making the step now and enjoying lower energy bills and often faster hash rates.

Update

After further optimization and some trade-offs, we came up with this updated estimation results based on our improved design.

Hashrate: 1.00GH/s per chip
Area: 21.7mm^2 per chip
Power Consumption: 8.23W

Again remember that they are estimated from the RTL design and might have some differences to real products.
