OMAPL137 EVM G711 and WMA codec examples

Ping Tai
Prodigy 210 points

Hi OMAP Team,

I am using OMAPL137EVM. There is a AIC3106 codec interfaces to the OMAPL137 via McASP1. Microphone input and line output are through AIC3106.

One of my purpose is to take voice from the microphone and encode in G711 in DSP side, this G711 encoded voice stream will then be taken from an application in the ARM side. This ARM side application send this voice stream back to the DSP side. The G711 decodes the coming voice stream and routes the decoded stream to the AIC3106 and then to the line out.

Do you have any similar or close examples that can facilitate my programming?

Regards,

Ping

    Hi Ping,

    The SDK which comes along with the omapL137 EVM includes examples for communicating ARM and DSP processors.

    As well it contains codec engine packages which facilitates communication between ARM and DSP.

    you will find more information on codec engines through this link :http://processors.wiki.ti.com/index.php/Building_The_OMAP-L137_SDK

    May I recommend you to go to the TI Wiki Pages and search for "omapl137 codec" or "omapL1x" (no quotes) to find some documentations that will be helpful for you to go through the already existing information on omapL137.

     

    Regards,

    Shankari.
