Porting Volib ECU example application to SYSBIOS

Other Parts Discussed in Thread: SYSBIOS

Hi

I tried to execute the test_rel_ce66le_CE66LE_LE_ELF CCS project on XEVMK2EX and found perfectly working. We also created a new project and followed all settings in CCS for including ECU library to the same. This project also worked with perfect outputs. However we tried same to create a SYSBIOS project and observing input and output of Echo canceller as same. No cancellation is observed as output, same time the exact input file will be regenerated.

i) Kindly request support for the reason behind the generation of same input file as echo canceller output and moreover it will happen only when i use a SYSBIOS.

ii) only difference is SYSBIOS; i add Volib Package through SYSBIOS .cfg available products window anyway the project build is success without any errors.

 

Thanks & Regards,

    Shino,

    I would like to first investigate the Rin samples if echo cancellation doesn't take effect. Are you able to share your SYSBIOS project here so we can take a closer look?

    Hi

    Thanks for the reply. I tried to add libraries in linker command file and found its working fine rather than adding packages from SYSBIOS available products tab.

    Since i was new to the Volib software library i need guidance regarding test_rel_ce66le_CE66LE_LE_ELF CCS project which TI has delivered with volib pacakage. My goal is to make the ECU module work for 64 channels.

    i) Kindly advice me the usage of SIU / PIU and mhm modules which is used in ECU examples. Is there any documents suggesting the usage instructions of mhm/ SIU/PIU 's?

    waiting for help

    Shino,

    I could not find the separate document of SIU/PIU used in the ECU of VoLIB. VoLIB mainly focuses on voice processing instead of generic framework/interface design. ECU provides unit test configuration and execution procedure which you probably already went through, if not, you can find it in volib_C66_2_0_0_3/docs/doxygen/html/ecu_test_html/config.html.

    Hi Garret,

    Could you guide where to look for the filter coefficients of the ecu filter, which keeps updated for each learning sequencce. Is it a part of instance? if so which field refers to it?

    regards,
