Making chips is expensive.  But once the chip is made, another $750k to
make a PC board with off-the-shelf parts around it?  Or is it mostly for
software porting, or what?

It also helps to have concrete evidence that what you're doing fills a
need, instead of being a solution looking for a problem.  This echoes
similar things you've said in the past about the GA chip.

May I ask what is involved in 2 years of something like that?  I'm
imagining a process like "download a 32-bit RISC core from
opencores.org, replicate 16 times, plus add some stuff for the shared
memory blocks".

I think the chip is targeted to mobile phones with little power
available.  The 16-core part's total commputational performance is lower
than today's desktop processors, and even the 64-core is not that much
ahead, especially if you count on-chip desktop GPU's.

I'd say though that gpgpu's are not so good at algorithms involving lots
of conditional branches, so these array thingies probably have uses.
The Xeon Phi looks interesting.
