Re-Build of TI DSP C64x+ Big Endian Library

Suresh Ramalingam

Hello,

I am using TI C64x+ Big Endian DSP Library . In the installed "lib" directory , there are three .src files and a lib file.

My Question is if I make a modification to the .Src files , how to compile them ? I tried using mk6x , but I am getting an error "File "dsp64pluse.src" not an archive" .

How to rebuild Big Endian TI DSP library ? ( In the installation folder there is no src folder as in Little Endian)

 

Thanks and Regards,

Suresh

    Suresh,

    I think you are using an older version of DSPLIB Big Endian. Please download the new DSPLIB 3.X that contains CCS v4, projects to recompile the library easily. The download for the new DSPLIB is mentioned below:

    http://www.ti.com/tool/SPRC265

    I am not sure why the src file is not being recognized as an arhive on your system but you might want to try unarchiving the .src files using ar6x -x <file_name.src> to obtain individual source files, modify the required file and then create a DSP project to rebuild the library with the extracted sources or directly use the source file in your project.

    Regards,

    Thanks Rahul. I will try the new BE DSP Lib. Also I have a question with this new Lib, does it have some fixes to the known scaling issues with the FFT16x16 of old BE DSP Lib ?

    I installed it. In the library installation folder there are two libraries :

    1)dsplib.a64P

    2)dsplib.a64Pe

     

    Which is Big Endian Library out of these two ? I couldn't find any readme.txt .

     

    Thanks

    dsplib.a64Pe is the big endian library. The release notes in the root install directory contains links to the documentation.
