It has some limitations but the speedup of a factor of 10 over the CPU (at stock clock rate) should make the Raspi competitive with newer, multicore Android phones when it comes to BRP, once I have some spare time to make a Raspi optimized app.
I've been successfully fiddling on the Parallella natively ie. working thru a TTY session to the ARM/Epiphany from my Ubuntu machine. Now wanting to transition to cross-compilation ie. use Eclipse + ESDK etc on the Ubuntu.
Check that you have a 64-bit OS !!
I didn't. I thought I did, but no. 'i686' is 32-bit, one wants 'x86_64' returned when one checks via 'uname -m' .... blah, there's time I won't get back.

On behalf of all of us who mostly have no clue what all the stuff in this thread means, I'm sorry, but I do understand this post and it makes me feel a little better about myself.

Darn. I actually got an email stating all that. But I ignored it as one gets many scams based on much the same premise - you get a link to a non-https site, invitation to re-enter details etc - so I did nuthin.
What I have done is delete my KickStarter account.
Cheers, Mike.

@HBE any progress on this front (the Raspi optimised app that is)?

FWIW : rounding off my prior analysis I have analysed the radix-4 case in detail.

Hi!
Meanwhile, there is now a GPU accelerated FFT implementation for the Raspberry Pi ARM SoC:

Worth noting that the BrownDeer people have produced an update for Parallella involving OpenCL ported to that ARM/Epiphany combo, which has caught my interest.

Hi!
Sorry, I haven't yet found the time to look in depth into the Raspi GPU FFT.
Here's another development: NVIDIA will sell an affordable development board for the new Tegra K1 ARM SoC that features a CUDA capable GPU:
