1. Good Luck 2. Keep posting, we are interested in a fixed point version of speex and would try to colaborate. Our need isn't as immediate but if you set this up correctly we and (hopefully) others will try to collaborate. 3. I'm interested in the methodology for creating a fixed point implementation and guaging how "good" it is relative to the floating point golden standard

Then I'll enter into serious discussions about

I''m building a 10 branch/1 headquarter network with Shorewall/Linux as gateway on all locations. The TI guy asked me if there is a way to ''cache'' TCP/UDP traffic between them. I crawled on Internet and I only find very expensive solutions for this. Some of them appeared in this comparison article: http://www.networkcomputing.com/showitem.jhtml?docid=1524f5 Does anyone

Hi, I can see that there has been some effort to compile the SPEEX codec to operate on the TI c54x and c55x DSPs and I am wondering if anyone would be able to update the mailing list with their current MIPs and Memory resource requirements for their c54x and/or c55x compilation? The only estimate I was able to find in the mailing list archive was 42MIPs but I'm not sure if this is an

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

Hello ! I am developing a kind of phone using TI's OMAP 5912 and speex. The soft works great on ARM, and it is time to move speex and voice processing stuff to DSP. Could some one point me how to do it ? Should I install CCS ? Or it possible to compile speex using just ti_dsptools ? Does anybody ran speex and dsp gateway ? It would be great, if some one share makefile, cmd etc. for

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, My name is Jean Quirion and I am a DSP engineer. Currently I am working on a project where it is desired to implement a VoIP solution over a GSM GPRS link. I would like to use Speex as the vocoder for this application. This application would require the Speex encoder/decoder and possibly the pre-processor to run on a low power fixed-point DSP such as a TI C55x. Thus, I am interested in

Jim, Thank you very much for your suggestions. I managed to get the C55x code working on the simulator. I would like to port Speex both on a C5502 EVM and a C5509A EVM. As such, if you can provide me with the details of your port on the C5509A, it would be greatly appreciated. Furthermore, I am looking for some technical documentation on the CELP algorithms. I would like to better

Hi Jim, > Build 11169 in SVN works correctly. Good.

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)

Greetings, I have found that QCONST16(32.f, 10) yields different result (from gcc 4.4.7 ) when the code is compiled for TI C55 or C64 DSPs. gcc - result is 32767 TI compiler result is -32768 (C55 compiler version 4.4.1 and C6x compiler version 7.4.2) Although not in the current code, QCONST32(32.f, 26) results differ in similar fashion. Judging by the use #ifdef TI_C.. in the code base, these

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

Jerry, Thanks for the response; basically, I need to get just the narrow band working now (maybe use advanced features such as jitter buffer, echo cancellation, VAD, etc in the future); the DSP will do the encode and decode simultaneously as data are available. My main objective is just do a voice application that runs on the ARM side of the DaVinci with the codec running on the DSP side; the

Thanks Jean-Marc. Is there a Speex trunk for the C64xx I can use? Or do I have to figure what options to turn on (in configure) when building the library? Thanks.

Hi, My company just recently bought a TI DaVinci development board and I'm trying to port Speex to run on it. The TI DaVinci chip has an ARM926 processor and a TMS320C64+ DSP in it. I was able to get Speex somewhat working on a TMS320VC5510 about a year ago but I was wondering is there anything special I need to do to get Speex working on the TMS320C64+ DSP in the DaVinci chip. I

It would be great to get some idea of what chips and DSPs people have tried to compile Speex for, and what success they've had. So, if you've tried Speex on a chip, could you take a second to fill in the following and post it to the list? Chip Name: Speex Version: Floating or Fixed: Encode, Decode, Both or Simultaneous: MIPS (if known): Other comments: Many thanks, Gerv

Hi Developers, I searched the archives and found a discussion about hardware decoders using dsp chips. Has anyone done any research or development on a high-speed encoder? I think it would be cool to have an encoder that could keep up with the high speed cdroms on the market. I was thinking of getting one of the evaluation kits from TI or Analog Devices and trying to port the library to them.

I saw a thread in the list archives about a speex port to TI 55x DSP. Wondering how that worked out (is working out)? Also wondering if there is a source archive for it, or if the patch in the email archives is still current, or if there's been updates. Any info appreciated. Thanks Paul
