[RFC PATCH v1] arm: kf_bfly4: Introduce ARM neon intrinsics
Optimize kf_bfly4 function using ARM NEON intrinsics
for SoCs that have NEON VFP unit
As initial step, only targetting ARMv7-VFP based SoCs.
To enable this optimization, use --enable-armv7-neon-float
when running configure command. This is disabled by default.

[RFC PATCH v1] arm: kf_bfly4: Introduce ARM neon intrinsics
Hello,
I see from [1] Jean-Marc comment that opus project is open to adopting
ARM focussed fft optimizations in NE10 project/library at [2].
In light of this information, if and when fft implementations for 60,
120, 240, 480 become available in NE10 library,
a. Will the approach of enabling this optimization using
--enable-armv7-neon-float or similar flag be acceptable to begin with?
or
b.

AEC frame size
?
hi all,
i am using the Acoustic Echo Cancellation from "Speex 1.1.12 version" in my VOIP application. Is it that the frame length to be chosen should always be 20ms or can i have flexibility in chosing the frame lenght?
on what parameters does the frame length choise depends?
thank you all,
Shri.

Echo canceller problem
Hello everybody.
I have the same problem like you. I use ARM microcontroller too.
Here is the list of all functions called by speex_echo_cancel until goes
into infinite loop:
speex_echo_cancel()
|
spx_fft
|
kiss_fftr
|
kiss_fft
|
kiss_fft_stride
|
kf_work
Function kf_work looks like:
static void kf_work(kiss_fft_cpx * Fout, const kiss_fft_cpx * f, const
size_t fstride, int

[RFC PATCH v1 0/3] Introducing ARM SIMD Support
libvorbis does not currently have any simd/vectorization.
Following patches add generic framework for simd/vectorization
and on top, add ARM-NEON simd vectorization using intrinsics.
I was able to get over 34% performance improvement on my
Beaglebone Black which is single Cortex-A8 based CPU.
You can find more information on metrics and procedure I used
to measure at

[PATCH v1] cover: armv7: celt_pitch_xcorr: Introduce ARM neon intrinsics
Hi,
Optimizes celt_pitch_xcorr for ARM NEON floating point.
Changes from RFCv3:
- celt_neon_intr.c
- removed warnings due to not having constant pointers
- Put simpler loop to take care of corner cases. Unrolling using
intrinsics was not really mapping well to what was done
in celt_pitch_xcorr_arm.s
- Makefile.am
Removed explicit -O3 optimization
- test_unit_mathops.c,
