similar to: Speex on ARM in Real time

steve, i have run speex succesfully on windows mobile platform. check out our product on www.spokn.com and you can download the smartphone/pocketpc version (yes, the same binary works for both) from http://mobile.spokn.com. we have also made binaries for macintosh (www.spokn.com/spoknmac.dmg) as well as the regular windows xp. the linux client is being readied for fully open-source GPL-ed

Jean-Marc, Is there some document somewhere that outlines the ability of Speex to encode on ARM processors in real time, at the various bit rates and complexity settings? If not, can you give me some anecdotal information on the topic? I am interested in a real-time encoder for Windows Mobile 5.0 with XScale 416 MHz platform. As you may know, X-Pro for Pocket PC is a VoIP softphone

Hi JM, Thanks for the earlier replies. I have tested it with quality 1,2&3 the result is not much different. Also I must tell you that I am using the armbe-linux-gcc compiler which does not suppoort arm5e-asm optimisations. I get lots of assember related errors. Is there any alternative? Will moving on to a board supported by arm-linux-gcc compiler ,to enable arm5e optimisation, help?

Hello everyone, Can any body please tell me the compiler options to optimise the speex code for ARM TE architecture. Fixed point is enabled. It currently takes about 700ms to encode 5 sec worth of voice. I need to get it down to under 10ms. Is the option --enable-arm5te-asm supported? I am using speex 1.1.12 version. The configure.ac file does not seem to support --enable-arm5te-asm

Hi JM, I am using narrowband mode with speex qaulity set to 0 and complexity set to 4. The code works fine on the 3.2GHz processor. The test program speexenc takes 7ms to encode 5sec worth of voice on the 3.2Ghz processor. The same takes 700ms on the ARM5E intel Xscale. The code that I wrote puts 10 speex frames in one RTP packet. When exexcuted on ARM I get lots of underrruns hence

Hello, I am trying to build a speex library file for armv6 on intel MAC OS. I've also put -enable-arm5e-asm whether arm5e-asm works or not. ./configure -prefix=/Users/mijin/temp -disable-shared -enable-static - enable-fixed-point -enable-arm5e-asm This gives below errors. gcc -DHAVE_CONFIG_H -I. -I. -I.. -I../include -I../include -I.. -g - O2 -fvisibility=hidden -MT cb_search.lo -MD

Hi, I tried the same options suggested in your post and the problem continues.

Hi Eduardo, All I can say is that the timings you have are a bit odd. What optimizations options are you using (I suggest -O3)? Also, perhaps you can try --enable-arm4-asm just in case. I've had the encoder running in real-time on a chip that's at least twice slower than yours with the settings you're using. Jean-Marc Le jeudi 15 septembre 2005 ? 16:23 -0400, Eduardo Bezerra a

Hi, I'm trying to get speex working on an ARM board (ARM926EJ-Sid(wb) core, ARM 5TE architecture) and getting segfaults if build with "--enable-fixed-point --enable-arm5e-asm" options. If I use just "--enable-fixed-point", then it runs fine, but once I add "--enable-arm5e-asm" it start crashing (I use testenc to test it). Further investigation showed, that it

Hi, A question, How to embed inline assembly in EVC++? Can EVC link with obj file generated by pocketgcc? thanks James (sorry , last time I sent it to *.ca) On Sat, 26 Mar 2005 11:11:50 -0500, Jean-Marc Valin <Jean-Marc.Valin@usherbrooke.ca> wrote: > Hi, > > Assuming you have gcc, you can already compile with --enable-arm5e-asm > and get good results. Right now, many

Did you test what happens if you only enable arm4 assembly? Also, if you can do some investigation, it would be useful to check what bit of assembly is causing the crash. Can you disable one at a time and check?

Hi I want to port speex to my pocket PC iPAQ1945 which has a Samsung processor 2410, an ARM9-based processor. I would like to write the specific optimized code for this chip. I had some experience at DSP chip and fixed-point coding but know nothing about embedded system and ARM. Could someone tell me some hint how to write optimized code for this pocket PC. If you can give me some links that will

I'm developing a Personalized system of news audible for PDAs(Pocket PC and Palm OS), I have somes PDAs with differents processors(Samsung (2410) 266 MHz, Intel Xscale PXA 250 to 200 and 400 MHz, OMAP1510) with Pocket PC 2002 and 2003, and Palm OS 5 operating system. I offer myself to test any application of speex that runs in these machines, only you must send me the source code. Regards.

hi, i have searched through the archives but did not manage to find benchmarks of encoding/decoding speex on ARM processor. esp interested in ARM9E. understand that ARM5E has some dsp-like instructions, wonder whether they are compatible with those in ARM9E. thanks in advance. tk -------------- next part -------------- An HTML attachment was scrubbed...

Hi all, I'm trying to use libspeex 1.1.10 on an ARM926EJ-Sid(wb) rev 3 (v5l). I executed the speexenc and speexdec test files and they can encode and decode. But I'm getting 95% of cpu utilization on the codification and 44% on the decodification. I saw in the post: http://lists.xiph.org/pipermail/speex-dev/2005-June/003485.html that this version of speex works fine on ARM

Most of the WMMX instructions have MMX/SSE equivalents, plus there are a few other interesting functions. We have been thinking about doing WMMX optimizations of the various speex asm functions,

I work with the Microsoft Embedded Visual C++, and i don't have a linux machine with me. I need to have the best performance in order to run my application for the Intel XSCale with MMX. I don't know if i can compile for this processor with the best performance using the Microsoft compiler. I would like a help regarding how to get or build this .obj. Thank you. Cesar Bremer Pinheiro

Hallo, I am playing arround with dovecot I hat version 1.0.beta7 running fine. After installing beta9 there is a problem with default_mail_env setting. I have all users in ldap. there is an attribute "mailMessageStore" which contains a relative path to users maildir mailMessageStore: sca/ my mailer completes this relative pathinformation to /var/mail/sca/ therefor I setup

Hi, I'm not even sure what WMMX is, so I have no idea how to use it. For sure you would at least need to write some assembly. As for the current inline assembly parts (for the ARMv4 arch), you would need to convert them to VC++. It shouldn't be too hard, just push/load the registers at the beginning and then save/pop at the end. It's just the small macros (in fixed_arm4.h) that you
