AIC3254 MAXIMUM DELAY FOR PACDEC DELAY COMPONENT

Other Parts Discussed in Thread: TLV320AIC3254EVM-K

Hello Guys, Hello  and  Justin Bohr , , , and all Engineers,

I want to add delay about 300ms for my audio application. Is it possible?

Pictures depicted below are my current process flow and I manage to achieve about 128ms.

      

If I put size7+size1>700, then I got output error. Is there any limitation of the delay? Any help would be much appreciated!

Thanks and Best Regards,

kal

    Hi Kal,

    Check the Resources window after compiling. It will tell you what caused the limitation. It possibly failed due to exceeding the Data RAM limits.

    Thanks  for the answer.

    Anyhow, could you please suggest an advance version of TLV320AIC3254EVM-K that can have up to at least 13,230 samples with 44.1kHz sampling rate.

    Current  TLV320AIC3254EVM-K version can only have up to 4800 samples.

    Thanks,

    kal

    update: 21/4/2015

    below process flow can support up to 9600 samples.
