Not only is this enough to encode/decode in real-time, but you can probably do ~50 channels (or more) at the the same time.

They claim to max out at 1,800 MFLOPs And have a clock speed of up to 300 mhz.

Anyone have any idea if the any of the Sharc or TigerSHARC DSPs are powerful enough to do realtime Speex? <p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'speex-dev-request@xiph.org' containing only the word 'unsubscribe' in the body.

Jamey, There is a previous posting in the speex archives with a link to the dsp c5x patch.

hi list, SHARC, is a kind of DSP Processor from ADI. Who are making a backend for it, or already have one? If your code's not for business, would you mind share it for me? even incomplete is appreciated. Thanks, all. linduan at isoftstone.com -------------- next part -------------- An HTML attachment was scrubbed... URL:

Sorry everyone, but I figured it out; it's working now. The problem was in my monoToStereo and stereoToMono functions (the Linux OSS driver on the ARM side only supports stereo so I had to convert it to mono before feeding it to Speex); also I had an alignment issue with my buffers I was using on the DSP side. Thanks Jim/Jean-Marc for your help! Regards, Andy ----- Original Message ----

Jean-Marc, I have attached a small patch with modifications to arch.h, bits.c, and misc.c. This contains the few mods remaining to support the various fixed point TI DSPs after the work that you did at the end of May (thank you for this). arch.h: Add switch for compilers not supporting "long long" (C55x does, C54x and older C64x does not) bits.c: Allow external definition for max

Hi, I've been trying to get Speex to compile and run on the DSP of TI's new DaVinci System-On-Chip processor, which has both an ARM (ARM926) and a DSP (C64+, based on the C6400). I used the latest code (1.2beta) and followed the example in the speex- 1.2beta1/ti/speex_C64_test trunk to build the Speex library for the DSP. Basically I have a loopback application on the ARM that samples

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

We are bellow 30MIPS for our 16bit single MAC fixed point DSP. 8khz/8kbps I aggree with Jean-Marc that MIPS is dependent from the target DSP, but it's a very good indication when you compare same architecture DSPs. It is very difficult (impossible) to use effecient a DSP using only c. George ----- Original Message ----- From: "Andre Borrelly" <andre@myavalaunch.com> To:

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

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...

Hello Jean-Marc, et al: I'm sorry to have been unclear. I do prefer two separate code bases. How do you suggest that we get a mailing list together? Please include me. I'm still suggesting another addition to the agenda ... again looking to acceptance by a using community. I'd like to see us target specific processor/s with the fixed point code we are creating ... inlining
