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:

http://www.raspberrypi.org/archives/5934

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.

Cheers

It's official : I am an idiot

It's official : I am an idiot !! :-)

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.

Cheers, Mike.

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.

You're welcome David. :-)

Always check your assumptions ..... fake it 'til you make it ....

If you haven't yet, reset your password at Kickstarter, as it got hacked and all passwords and email addresses got stolen. http://abcnews.go.com/Technology/passwords-email-addresses-leaked-kickstarter-hack/story?id=22553952

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.

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.

Cheers, Mike.

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

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:
