Hello Carl, Can you send me libspeex compilated in eVC. And can you describe where and how set the FIXED_POINT flag in eVC. Thanks you. Regards.

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

Hi all, I'm trying to create a speex decoder library for Pocket PC platform. I then intend to use this library within my .NET Compact Framework application. But when I simply try to compile the libspeex files within my eMbedded Visual C++ environment, I receive the following error c:\documents and settings\asheeshv.grapecity\desktop\pocketpcdll\speex\bits.c(367) : fatal error C1010:

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.

Hi all, I'm quite new to Speex and i'm tryng to do a porting of it for my pocketpc platform.... The encodig time seem to be too hight, i think something goes wrong putting --enable-fixed-point --enable-fixed-point-debug --enable-arm-asm in project setting of EVC++ 3.0 (i've got EVC++ 4.0 too) i do my test with an Ipaq 3850 (206 MHz Intel® Strong ARM 32-bit RISC Processor) running

I don't think a compiler is going to be enough. I tried perl scripting the output of a linux gcc cross-compiler to convert into something the assembler under eVC would consume. It errors on all the MAC type of instructions. I looked at www.arm.com (I never knew there could be so many arms) It does not look like the ARM720 has the MAC instructions. It also lists 75Mhz and 100Mhz as possible

Hello Greg If money isn't a problem Intel has an optimized compiler for eVC and XScale processors http://www.intel.com/software/products/compilers/techtopics/PCA_Optimization_WP.pdf If you have any luck getting the eVC compiler closer to realtime I'd really like to know. I'm still far from realtime when using Speex 1.1.3 on a HP iPAQ (Intel pxa255). Best regards Bjoern D.

Hi, I am probably missing something really simple (since I don't know very much about compiling or anything) but I am trying to compile the latest version of Speex (1.1.10) into a .lib file. I have compiled it with GCC under Cygwin with -enable-fixed-point and --enable-static, and have produced a .a file. I want to be able to use it with eMbedded Visual C++ 4.0. I guessed that I would need

I'll try fixing that. It's funny "gcc -ansi -Wall" doesn't even complain about it despite the fact it's not C89-compliant. In the mean time, you can always replace it with: spx_word16_t w[1024]; and you'll be fine (unless you try AEC with a frame size > 512). Sorry about the inconvenience. <cheap shot>Must be the price to pay for using an inferior

Hi all, I'd like you to know i'm not able to build Speex library anymore from CVS without modfing the code in mdf.c. This is due to the fact that EVC++ compiler doesn't like memory allocations in this form: spx_word16_t w[N]; where N is not a constant. I know this is not an error for gcc compiler and ANSI standard but it is in VS2005 and EVC++ 4.0 If someone knows how to compile

Yeah, MSVC doesn't like that notation.. You can use alloca which allocates stuff on the stack instead I believe. -----Original Message----- From: speex-dev-bounces@xiph.org [mailto:speex-dev-bounces@xiph.org] On Behalf Of Ralph Giles Sent: Tuesday, December 20, 2005 9:52 AM To: Jean-Marc Valin Cc: Speex Mailing List Subject: Re: [Speex-dev] CVS compilation and EVC++ 4.0 On Tue, Dec 20, 2005

Target is Spv & Nokia phones ARM and also ipaq ARM. With the generic fixed point at complexity 0 I am still about 1.6x realtime for narrowband. The MS eVC compiler does not support inline assembler, only separate assembler functions. Does anyone have a feeling on whether a 2x speedup is possible if I hand tune a few functions? -greg. --- >8 ---- List archives:

How big is difference between encoding speeds of libspeex compiled with arm-asm, and without it? My application is written in EVC++, but there is no inline assembler, so I have to compile speex without arm-asm. But I still trying to find a way to use speex with arm-asm under my EVC++ application. I tried to compile speex with arm-asm under gcc (arm-wince-pe), but generated static link

Hi Fabio, In theory, speex would run in real time, because now it was implemented with integer functions (before only floting point). I'd like test it in my arm processor. I hope to port speex to ppc soon. For your thesis see this link http://www.chl.chalmers.se/~numa/theses/voicemail.pdf Regards, Rodrigo <p>-----Mensaje original----- De: owner-speex-dev@xiph.org

I've been able to do real-time with about 20% CPU on an ARM 400 MHz. Here are the settings I used: - Compiled with FIXED_POINT (--enable-fixed-point) and ARM_ASM (--enable-arm-asm) -

Well, you seem to be using FRAME_SIZE but only defining frame_size. Otherwise, the code looks OK, but it's always hard to tell. I suggest you start from speexenc/speexdec or from the example I wrote in the manual at: http://www.speex.org/manual/node12.html Jean-Marc Le ven 19/12/2003 à 05:22, Fabio a écrit : > Hi > i'm developing a sort of VoIP application > for my

Hi Rodrigo, I'm Fabio and i'm in your identical situation, i need Speex to run on PocketPC in real time mode for my tesis. I've to develop a sort of VoIP apllication for pocketPC... I recently discover speex (Only yesterday i joined this mailing list....) and I'm doing many test using mostly VC++ 6.0 but only because i'm still undestandig speex... I did many works with EVC++

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
