CCS/TMS320C5517: AER and beamforming algorithms running simultaneously on C5517

Aleksandar Atanasovski

Part Number: TMS320C5517

Tool/software: Code Composer Studio

Hello everyone,

We are running http://www.ti.com/tool/TIDEP-0077 based solution for beamforming a microphone array.

Since we hear a lot of echo in our device that contains 4 microphones linear array and BF/MSS algorithm, we decided that we should try to add AEC/AER processing from the Telecom library.

C5517 chip runs @ 200MHz and our sample rate is 16KHz.

Even then, we are concerned whether C5517 is capable to run beamforming with MSS and ASNR with additional AEC/AER algorithms.

Does anybody already try that since the initial example for EVM doesn't contain any echo cancelation included?

Hello,
I will check if performance of C5517 @ 200MHz / sample rate 16KHz will be enough to add AEC/AER and will come back to you soon.
In the meantime can you tell me if you recalculate coefficients for the beamforming filters or use these in the example?
I am asking this because there was a known bug in the tool for generating filter coefficients and if this is the case you may not need to add AER to achieve satisfactory results. Here is a thread about this

Hello,
can you please answer about recalculated coefficients (or not).
Thanks

Hi Michail,

Thank you very much for your support. We will try that asap. We also have the ability to enable/disable ASNR and DRC in runtime and to record the sound in both cases.

After that, we will share our findings with you.

Thanks,

Aleksandar Atanasovski

Hi Aleksandar,
it is good that you're not blocked and able to make your tests but since this can take some time I'll prefer to close the thread for now and when you come back you can reopen again.

Hi Mihail,

Thanks for your support.

Unfortunately, I was not able to run bfgui tool. I tried on several PCs and always got the following output on the console after running bfgui.exe :

??? Undefined function or variable 'bfgui'.

MATLAB: UndefinedFunction

Is there anything that should be installed additionally on PC besides MCR ? I am using Win10.

Hi,
I found that:
"MATLAB R2015a and later is supported on Windows 10.
Earlier releases of MATLAB are not supported and are not guaranteed to work on Windows 10."
So you can check your version for compatibility.
