similar to: speex optimisation for ARM 5TE architecture

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 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, 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

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?

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 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, 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, 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 llandre, I think it's worth trying the float version on your CPU. However, I wouldn't be surprised if the fixed-point was still faster than float. BTW, you can use --enable-arm5-asm instead of --enable-arm4-asm. While both are currently almost the same, eventually it would be possible to get better performance using the ARM5E DSP-like instructions. Jean-Marc > This processor

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

(Resending since the archive seems to have eaten the text.) I'm working on getting Speex running on a TI Davinci (6441), on both the ARM and the DSP. My immediate goal is to understand the processing requirements on different architectures so that I can properly specific an engineering project. I have it up and running on the ARM, and I just wanted to see if anyone could sanity-check

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

Well, all ARM9E cores use the v5TE architecture, which means Thumb and DSP-friendly instructions. Ettore Benedetti THALES COMMUNICATIONS B.V.

I thought a 416 MHz XScale should be able to encode+decode in real-time at pretty much any narrowband or wideband bit-rate, though in some case, it may be good to reduce the complexity to 1. There may be a few bit-rates that could cause problems because they aren't fully converted to fixed-point. Also, if your ARM chip supports the ARM5E architecture, there may be some big gains you could get

Hi All, I have downloaded libogg-1.3.0 along with speex.But,during build speex is exiting with ogg.h missing.Any suggestions will be highly appreciated. --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
