<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: courier, monaco, monospace, sans-serif">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</DIV>
<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: courier, monaco, monospace, sans-serif">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 application on the ARM will get from and give to the DSP Speex encoded data via shared memory. On the outbound flow (to ARM), the DSP basically continuously samples a mic, encodes it in Speex format, and give it to the application on the ARM side via the shared memory; on the inbound flow (from ARM), the DSP gets encoded Speex data via the 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 work for the C64xx series? Thanks.</DIV>

I did some work optimizing the DM642 speex 1.1.11.1 encoder earlier this year. I was able to reduce the narrow band MIPS from approx 30 to 16 using some of the #pragmas and optimizing the functions (Following the BlackFin example.) The project I was working on has been put on hold so I havenąt looked at the more recent changes. If you are tight on MIPS, there are plenty of opportunities to optimize Speex following the BlackFin example.</SPAN></FONT></P>

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 appreciate any insight or comment you may give me or point me to sites where I can get more information. Thanks in advance!</SPAN></FONT></P></DIV>
