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 understand the math being implemented. Do you know where such documentatio...

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

This build runs 8kbps narrowband, with minimum complexity. Changed files (from 1.1.10 base): arch.h: Add switch for compilers not supporting "long long" (C55x does, C54x, old C64x does not) bits.c: Allow external definition for max buffer size, change MAX_BYTES_PER_FRAME...

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

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.

yes, our DSP is 16 bit based, and if those bits of code aren't using 32 bit variables then yes that is what the warnings would be. Does this mean that the preprocessor and echo canceller won't work as well because of this? -Mike >>> Jean-Marc Valin <jean-marc.valin@usherbrooke.ca> 01/18/08 8:42 PM >>> I think these warnings are due to your DSP being 16-bit and

dear sir/madam, i am runnin the speex codes for the TI-DSP in CCS. i have also given the same input file that has been mentioned in the readme-TIDSP. the code runs perfectly ( i think) but it takes a lot of time for the *.out file to "run". the output file, which is supposed to be "maleout5x" has a size much bigger than the input file "male.snd" (the input file is

I use Speex on a C5509A DSP, which has 256k bytes of RAM for code and data. Speex fits very comfortably in less than half of this memory. However, I do not have room for the echo canceller code in my overall application. In your case, with the large Flash, the code space should not be a problem. However, I believe t...

The TI directory of the Speex source distribution contains a C5509A project that builds and runs in TI's Code Composer Studio simulator. This project does file I/O to files specified in the main source file. See README.TI_DSP in the main directory for some tips. You should use the 1.2 beta 3 distribution. You should be able to load, build, and run this with...

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

There is a port for the TI C55X, in the TI directory of the source tree. This builds and runs directly on the TI C55x simulator (Code Composer). I have run this on the Spectrum Digital C5509A EVMPLUS board, by modifying some of the sample audio drivers (I could provide some details if you chose that board). You can certainly get started in the simulator. The Speex port does not include any assembly optimization for TI, so that is an area that you might be interested in. If you are co...

Mike, I played briefly with the echo canceller on the C5509A back in May 2006. I got the same compiler warnings, and sent a message to the list which included this: "I got several compiler warnings for "shift out of range" in mdf.c, which I fixed by adding EXTEND32 to all of the SHL32s with 16 bit operands (st->frame_size in 6 places, s...
