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 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?

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

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

Hello everybody (I'm new here) I am looking for 2 specific functions. The first one is a variance formula that does not divide by n-1 (I don't want the unbiased formula, that's it). In case it does not exist, how do I modify the default function code? Yes, a workaround would be to multiply the result by n-1 and then divide it by n, but I'd like to use a separate function, if

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, I'm trying to determine the phase of irregularly sampled data. Is there any particular reason why both spec.pgram and spec.ls return phase<-NULL for vectors? Thank you.

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, I was wondering if anyone had managed to get speex to run (nicely) on an IXP425 processor. The current version does not seem to have the necessary optimisations for the ARM v5te, just the v5 which has assembly optimisations not understood by this target. Failing that, does anyone know where I might get a reference for this model of processor? I have look on the Intel site, but I can't

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?

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 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, I am getting the following dump while trying to build for arm ./configure --prefix=/root/dump --host=arm-linux --with-gnu-ld --disable-static --enable-fixed-point --enable-arm-asm -enable-arm5e-asm configure: WARNING: unrecognized options: --enable-arm-asm Type "make; make install" to compile and install Speex root at rony-ubuntu:~/speex# make make all-recursive make[1]:

Hi all Speexers, I've done some optimization to current SVN fixed-point on ARM9E platform. If the RVDS simulator gives the MCPS(Million Cycle Per Second) value A, then actual MCPS on real CPU will be around 2*A. I don't know what cause the big gap between the simulator and real CPU. What do you think? BR, Lianghu -------------- next part -------------- An HTML attachment was

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
