similar to: Patch: ARM: fix inline assembly when compiling for Thumb-2

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

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 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, 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 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, 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 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 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

Features ======== * Win32 and Linux tested * Travis CI test added * Generates working Visual Studio 6.0-2017 solutions * Generates working Unix Makefile * Supported options (<option> - <default value>): * `ENABLE_FLOATING_POINT` - on

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

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...

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

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

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

(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

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
