TMS320C6748: using AER and Speech CODEC together?

Part Number: TMS320C6748
Other Parts Discussed in Thread: SYSBIOS

Team,

refering to the below SW:
http://www.ti.com/tool/telecomlib
http://www.ti.com/tool/c64xpluscodecs
http://www.ti.com/tool/c66xcodecs

Is a double buffer needed between the AER and the SPEECH CODECs?
Or can the data be passed directly between the two?
How could those two algorithm be pipelined in order to minimize the latency?

Thanks in advance,

Anthony

  • Hi Anthony,

    I've notified the RTOS team. Their feedback will be posted here.

    In the mean time, could you please share which versions of the above libraries are you using/planning to use? Which RTOS SDK version are you running?

    Best Regards,
    Yordan
  • Hi Yordan,

    The SYSBIOS released has not been choosen so far.

    The libs that will be potentially used would be:

        -aer_c64Px_obj_17_0_0_0_Win32.exe either on C674x or C66x

        -G7xx Encoder and Decoder, Version 2.00.00.000

        -OPUS Encoder and Decoder, Version 01.00.02.00

    Additionally to the previous questions:
    The AER docs (AER_installation_verification.pdf at http://software-dl.ti.com/libs/aer/latest/index_FDS.html  ) mention at page 5 some specific CGTools (CGT 7.4.02 for C6000) and XDC version to use to re-build the test.
    Can the test be build and ARE be linked using CGTools 8.x on CCSv 7.x?

    Thanks in advance,

    A.

  • Anthony,

    AER is 10ms frame based signal processing and supports 8KHz and 16KHz sampling rate. Depending on the frame size of speech codec, you may need have more buffers to pass between them.

    The AER is only tested with the CGT7.4 and XDC version as specified in the document, but we don't expect major issue with the new CGT8.x and CCS v7.x.

    Regards,
