I m transferring data from neon register to arm register, which is very costly.
i.e., it takes each vmov.32 r6,do[2] takes around 13 to 18 cycles.
This is proving to be very costly for a function which runs for many times.
Can anyone please suggest a way out of this???
Thanks in advance for any help..... :)
