[speex-dev] Libspeex-cygwin-EVC++ 3.0

I have built the Speex library for Pocket PC using the FIXED_POINT flag in eVC 3.  It works fine.
I think the iPAQ 3600 (ARM SA 1110, I think this is a 200mhz cpu), is a bit slow for encoding in realtime. The Speex encode function takes 30+ ms to encode one 20ms sample frame in a debug build. I didn't try the release build with compiler optimization.

The iPAQ 3970 (PXA250, I think this is a 400mhz cpu?)  is just fast enough for realtime encoding - the Speex encode function takes 20+ ms to encode one 20ms sample frame without compiler optimizations, but with compiler optimizations and tracing removed, only on occaisional tests did I notice gaps in the stream.

My experiments were done with 1 channel, 16 bit, 8000hz samples, using Speex quality 3 and complexity 4.

<p><p>Hi all,
As someone knows i'm tring to develop a VoIP application 
for my ipaq 3850 (200 Mhz) using speex...
I guessed, for better perfomance, to build libspeex using GCC under linux or cygwin with 
--enable-fixed-point and --enable-arm-asm and use the compiled library under Embedded VC++ 3.0.
I don't know if it's possible and only today i started to read something about
cross-compiling so i wish to ask if someone did something similar to it
or can send me suggestion to achieve my aim...
 
Regards
Fabio
