I suppose that it all depends on the production quantity :) Well, the
ADSP-BF537 EZKIT is quite more expensive and does not provides too muchs
not included in the STAM... and if you like to see thing really
expensive, this is an example:

Merry Christmas and happy new year to all of you!

I think the ADSP-stamp is about $100 overpriced at least. there are boards
available with more capability for less. There is an old saying that noone
was ever fired for buying IBM, maybe that's why AD charges what they do.
meantime, microchip is laughing all the way to the bank...
That said, your board is about right if that is the price for the
development system. I do appreciate it was started for your own use.
Certainly the fpga and blackfin will do the job along with some good front
end electronics!
Merry Christmas to you and yours.

Simply ask ;)
Seriously, I think that this kind of things are not too much money, like
for example the ADSP-BF537 Stamp from Analog Devices
http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=ADZS-BF537-STAMP-ND
We are not building this one in large quantities, but we've used it as
an starting point for several projects (see the space projects section
on my web... all of them have one or more inside ;) )
Do you think that the STAMP from ADI is too expensive? :)

Javier

Gosh, Javier, I went to your website, and found one of my favorite
peeves:
it says "low cost" without a hint of the price. I've found that this
combination usually means "way out of my price class" or, "if you have
to
ask, it's too high", or "low cost for a big company with a research
budget".
Sorry, just my prejudices showing.

ARM or other general purpose CPU is interesting, but at what cost for
complexity and/or software development? It would require RAM, IO
support, and boot rom at the very least. Not insurmountable, but at a
cost to complexity.
If you are not planifying to use an embedded operating system like
uClinux or embedded linux, no need for external RAM or ROM. There are
lot of ARMs from several manufacturers with 256kB flash and 64kB RAM or
more for<$20, with a nice set of peripherals (USB, UARTs, CAN, even
Ethernet without the need of an external phy). Software tools can range
from free (GCC + eclipse) to quite expensive (IAR).
If you plan to use an embedded operating system, then more RAM, more
ROM...
We've an embedded processor board that includes a Blackfin, 16 or 32MB
flash, 32 or 64MB RAM and a 250,000 gate FPGA, and belive me, it is not
so expensive (and if it would be interesting for a project like this,
we
could try to make a series with special time-nuts price)
