similar to: Speex crashing on ARM with assembler optimization enabled.

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

Hi All, I'm trying to build speex for the mini2440 board, with this toolchain: http://www.friendlyarm.net/dl.php?file=arm-linux-gcc-4.3.2.tgz because speex is a dependency of the sip softphone 'linphone'. The 'configure' string I'm using is this: ./configure --prefix=/usr --host=arm-linux --with-gnu-ld --disable-static --enable-fixed-point --enable-arm-asm Other

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

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 am attempting to port the speex library to TI Davinci DM35x Family. My questions are: 1. What is the best ./configure option for it? Is it ARM5e / ARM4 ? when I tried these two the during the compiled a warning "I suppose you can have a [ARM4/ARM5E/Blackfin] that has float instructions?" 2. is there any available demos for the echo cancellation because I can get it

Hi there, I've just started to work with the great speex encoder on ARM9-based embedded platform. This is my configuration: CPU: Cirrus Logic EP9315 @ 200 MHz (ARM920T) o.s.: Linux 2.6.9-rc2-ep93xx GCC: gcc version 3.3.3 (DENX ELDK 3.1 3.3.3-10) without MaverickCrunch support ogg library: 1.0 speex command line configuration: ./configure --enable-fixed-point --enable-arm4-asm The code is

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

Hi there. The attached patch adds If-Then (IT) instructions to the ARM inline assembly in Speex, allowing it to compile in Thumb-2 mode. Traditional 32 bit ARM instructions can be conditionally executed depending on which flags are currently set. Thumb-2 requires an 'IT' instruction instead that affects up to the next four instructions. Note that when compiling for ARM 32, IT

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

wouldn't it be a good idea to have the libraray available as a binary for non-PC platforms like the PocketPC, Symbian and Mac? i am suggesting this as it will allow the developers to go ahead and program to an interface while the development continues. there are builds for symbian, pocket pc and linux already in the tar ball. putting their binaries on the download section will probably

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

The attached patch eliminates some warnings while compiling for ARM4 targets. It also simplifies the asm constraints a bit. Now we can use the ARM4 optimisations when compiling for PortalPlayer targets in Rockbox. Cheers, Dan -------------- next part -------------- A non-text attachment was scrubbed...

Hi! It seems that using a different compiler (I assume the development is done with MSC) uncovers various issues with the floating point. Here is the second one I'm seeing - DOMAIN error from sqrt(). In the open_loop_nbest_pitch(), this line: g = DIV32(corr[i-start], 10+SHR32(MULT16_16(spx_sqrt(e0),spx_sqrt(energy[i-start]) ),6)); The values are: e0 is 7.2 i is 142, start is 17

I have found that filter_mem2 fixed point does not match the inlined assembly version for arm4. Looking closer there appears to be an off by one error. It occurs when setting the value of mem at the end of the inner loop. In the C fixed point version this is done with a subtract. In the arm4 version instead of multiplying den by yi, it is multipled by nyi and then an add is done. This

Hi, I have one question: Will Speex run in realtime (both encode / decode probably simulateusly) on Nokia 6600 --- basicaly ARM9 104MHz with Symbian 7s after porting to its C++ or Java? I am thinking mostly about the worst quality encoding (optionally duplex). Can this processor make it? Oh 6600 has something about 6mb memory if I remember good.

Patch applied. Thanks. In case you're interested, there's plenty of ARM4 optimisations that need to be updated (since 1.1.12) :-) > Apart from that, the 1.2beta2 release is

Hi everyone, I'm planning on releasing Speex 1.2beta2 in the next few days. I'd appreciate if everyone could try and test the current svn to make sure no bug crept in for your favourite plarform/application. Cheers, Jean-Marc
