<DIV>Hi Andy,<BR><BR>Speex itself (the library) should work fine on the C64xx because from<BR>the libspeex point of view, just just another 32-bit architecture with<BR>no FPU. There wasn't anything special to do to port Speex to the C64<BR>(unlike the C5x).<BR><BR> Jean-Marc<BR><BR>ndno72-speex@yahoo.com a écrit :<BR>> Jerry,<BR>> <BR>> Thanks for the response; basically, I need to get just the narrow<BR>> band working now (maybe use advanced features such as jitter buffer,<BR>> echo cancellation, VAD, etc in the future); the DSP will do the<BR>> encode and decode simultaneously as data are available. My main<BR>> objective is just do a voice application that runs on the ARM side of<BR>> the DaVinci with the codec running on the DSP side; the application<BR>> on the ARM will get from and give to the DSP Speex encoded data via<BR>> shared memory. On the outbound flow (to ARM), the DSP basically<BR>>
continuously samples a mic, encodes it in Speex format, and give it<BR>> to the application on the ARM side via the shared memory; on the<BR>> inbound flow (from ARM), the DSP gets encoded Speex data via the<BR>> shared memory, decodes it and then plays it to the speaker.<BR>> <BR>> I know there's a Speex port for the TMS320VC5510 but will that port<BR>> work for the C64xx series?

I did some work optimizing the<BR>> DM642 speex 1.1.11.1 encoder earlier this year. I was able to reduce<BR>> the narrow band MIPS from approx 30 to 16 using some of the
#pragmas<BR>> and optimizing the functions (Following the BlackFin example.) The<BR>> project I was working on has been put on hold so I haven’t looked at<BR>> the more recent changes. If you are tight on MIPS, there are plenty<BR>> of opportunities to optimize Speex following the BlackFin example.<BR>> <BR>> -----Original Message----- From: speex-dev-bounces@xiph.org<BR>> [mailto:speex-dev-bounces@xiph.org] On Behalf Of<BR>> ndno72-speex@yahoo.com Sent: Friday, December 01, 2006 5:18 PM To:<BR>> speex-dev@xiph.org Subject: [Speex-dev] Speex support for TI DaVinci<BR>> processor<BR>> <BR>> Hi,<BR>> <BR>> My company just recently bought a TI DaVinci development board and<BR>> I'm trying to port Speex to run on it.
