Hi, i'm not an expert in dsp but i've seen there is some code to run speex on omap C5X dsp so i was wondering what is the status of this code. Actually my goal is to run a voip application which uses gstreamer on an OMAP 5912 board. As there is already a speex codec for gstreamer, i was wondering if this plugin can already use the dsp power or if there is the need for a new plugin. thank

Hi, I'm porting speex as a DSP task to run using the DSP gateway project. I have some results, but I still need some improments, because I'm still getting some error messages in the mail box system... If someone wants to help... it would be useful. 2006/1/16, Ralph Giles <giles@xiph.org>: > On Mon, Jan 16, 2006 at 04:43:56PM +0100, Christophe Augier wrote: > > >

The attached file contains build files for TI's Code Composer Studio (CCS) for the C54x, C55x, and C6x DSPs. I had intended to post this a couple of months ago, but it took a long time to get around to doing the little bit of cleanup required. This is a file I/O loopback application suitable for running with the CCS simulators, for evaluating memory and MIPs requirements for these

Dear Sir\Madam; Thanks for your source codes. You mentioned that your speex source code can be compiled for ti-c54 family; but you use linux command-line as following to compile speex for C54 family: % ./configure -prefix=<path> -enable-ti-c55x % make % make install Is it true?! Then what is the output file for loading on DSP chip (C54)?? As I remember the compiled file for C5x family

Hi, Just a couple tips to reduce complexity. First, I think you'd get a good speedup by enabling the PRECISION16 switch (if it's not done already). This (very) slightly reduces quality, but means you convert a lot of "emulated" 16x32 multiplications into 16x16. There are also several routines that would benefit from platform-specific optimizations. There are already

Hello, &nbsp; I have an OMAP5910 OSK board with C55 dsp and ARM9 processor. I just want to use speex as a simple application on the platform in order to check dsp's working well or not. &nbsp; First, I found speex's source codes include "ti/speex_C55_test" directory so I thought speex could run on my platform well. Second, I open "Code Composer

Hi, Over the past few months I've been developing a LLVM backend for TIs C64X family of DSPs. It can be found as a co-processor in a variety of OMAP-based devices such as gumstix, beagleboard and even Nokia's N900 phone. A project I'm working on [0] has had need to put code on it, and we wanted to avoid TIs proprietary compiler. The DSP itself is a VLIW machine, with 64 32-bit

Speex 1.2beta1 announcement: This new release brings many significant improvements. The quality has been improved, both at the encoder level and the decoder level. These include enhancer improvements (now on by default), input/output high-pass filters, as well as fixing minor regressions in previous 1.1.x releases. A strange and rare instability problem with pure sinusoids has also been fixed. On

Hi Jim, > Build 11169 in SVN works correctly. Good. I'll try not to forget the EXTEND32 from now on. > I have attached a zip file (renamed > .txt) with a patch to bits.c to make the byteswapping for TI DSPs > consistent. Seems like unzip can't read it. Either it's in an unknown format or the file got corrupted. Could simply send as multiple (uncompressed)

Hi Jim, Thank for the patch. I'll apply it when I have a few minutes. If I haven't done so after a few weeks, please send it again. I'm in the process of relocating to Australia, so everything's a bit of a mess around here. Also, please post the c5X-specific files to the list (.cmd, .pjt, ...) so they'll be archived. Last thing, I see you defined spx_word64_t as long long for

At the Ogg Vorbis page for developers (http://xiph.org/vorbis/) one can find this line: "The Tremor reference decoder provides an integer-only implementation of the decoder for embedded devices [SVN trunk] [low-memory branch]" I'm interesting in using the integer-only implementation off ogg vorbis but I wonder: what is the difference between these two downloads? (SVN trunk and

We are implementing a driver for a PCIe card that runs Linux. This card needs "virtual" network/disk/console devices, so we have reused the virtio devices on on the card and provided a host backend that interacts with the virtio devices through the card's driver. this approach is very much like what was proposed on this thread

Can we get a response from Verisilicon on this? We spoke at the VoIP developer conference and you seemed to indicate that Speex was too difficult for you guys to implement in your embedded products. Mr. Valin would like to know specifically what your criteria is to run on your silicon. He needs to know the following. What is the maximum code size that you can use? What is the maximum data

Just tried your files and I'm not running into any infinite loops and the cancellation works fine. Unless the C6x has the same problem, I suspect a 16-bit problem. I'll check and see if I find something. About the r=0 problem, I can't find where it ends up in a denominator, so I suspect is not (directly) the problem.

Hi, I'm use a DSP C5510 to implement a solution with voice, but I'm a beginner in the world of DSP, any one has a example or documents about how to use a speex in DSP's ???? Thanks.

Hi ! Can anybody point me how to compile speex for subj ? May be I'm doing something stupid.. I just took all files from /libspeex and added them to my project in Code Composer 2.1. Then I set global definitions CONFIG_TI_C55X, FIXED_POINT, DISABLE_WIDEBAND, RELEASE for entire project and edit arch.h and create speex_config_types.h. Then tried to compile it and run. Code seems to be hang in
