RDFT on NEON

[matteoMoro]

Hi everybody,

i'm very interested on using the fft algorithm on a cortex-a8 ARM
processor.
I'd like to get better performance by using the NEON processor.
My signals are always real-valued so the RDFT algorithm should be the
best for me.

I don't understand how is made up the output vector.

I have in the first half the real part of the fft coefficient and in
the second half the imaginary part of the coefficient? Or am I wrong?

Please give me some advice how to figure out it.

Thanks very much and many congratulations for the work you are doing

Best regards,

Matteo
