AIC33+DM355

Other Parts Discussed in Thread: CCSTUDIO

Hello Everybody,
The project I'm working on consists in streaming audio and video between two DM355 Evm using Gstreamer.
After many searches, I remarked that I require offloading all the audio processing in the gstreamer pipelines (Alsasrc, alsasink, osssrc...) to the DSP side and not to the ARM side because I have had a critical CPU overload.
So, I need to configure the DM355 EVM's AIC33 codec to be supported with my sound drivers.
I am wondering how to do this and what sound driver (ALSA or OSS) I have to activate.
Thanks in advance.

Regards,

    Idriss,

    I'm not certain I understand your comment on moving this to the DSP given that there is no DSP on the DM355, but it might be worth your while to look at the Spectrum Digital site for details on how the AIC33 is programmed on the DM355 EVM.  Please go here and download the test code here:

    http://c6000.spectrumdigital.com/evmdm355/reve/files/EVMDM355_BSL_RevE.zip

    Once you install the file inside go to C:\CCStudio_v3.3\boards\evmdm355_v1\tests\aic33 and you will find the test code.

     

    However, if you are implying that you wish to offload processing from the ARM onto the MJCP video coprocessor, that will not be possible.
