CCS/TMS320C6748: A question about the compatibility between TMS320C6711 and TMS320C6748

Part Number: TMS320C6748
Other Parts Discussed in Thread: OMAP-L138, TELECOMLIB

Tool/software: Code Composer Studio

Hello DSP experts. I am pretty new to DSP boards and I am currently trying to assist one of the PhD students in my department by implementing her algorithm on TMS320C6748.

During the last semester, I used OMAP-L138 for one of my classes but I did not learn the details such as its hardware spec and how to set the environment properly. I just used it to implement my assignment.

Anyway, the PhD student that I am helping gave me this paper about acoustic echo cancellation. And it used TMS320C6711 and a bunch of CCS support files to implement normalized least mean square algorithm.

The support files include c6xdskinit.c, c6x.h, c6xdsk.h, c6xdskinit.h, c6xinterrupts.h, vectors_11.asm, rts6701.lib and C6xdsk.cmd. According to the TI website, they do not provide TMS320C6711 and instead they

have TMS320C6713. I was trying to find the datasheet of TMS320C6713 but it is not easy. I just want to see if I can still use the CCS support files above on C6748. And I would be glad if anyone knows where I can get

those files. Thanks in advance.

    Hi,
    have TMS320C6713. I was trying to find the datasheet of TMS320C6713 but it is not easy. I just want to see if I can still use the CCS support files above on C6748

    Probably not, at least not with some modifications in your project. The TMS320C6748 has its own implementation of Acoustic Echo Cancellation/Removal. Find it here:
    www.ti.com/.../telecomlib

    The TMS320C6713 does NOT point to the above telecomlib, so most likely you will have to modify the above mentioned files inorder to use them in your TMS320C6748 project.

    Thanks a lot. 

    I will test the link you gave me. However, have you ever seen those CCS support files I mentioned above? According to the paper, I can get them from the CD accompanying Chassaing 2002, or the Texas

    Instruments DSK 2002. I have been trying to find them but it was not easy. Probably is it because they are too old? 

    Anyway, thanks a lot.

    Hi,

    Sorry these seem to be quite old and I am not familiar with them.
