Hello,

I am adding IMGLIB2 into my Code Composer project and am not sure whether to include the library file IMGLIB2.l64P or IMGLIB2_cn.l64P. Can someone please tell me the difference? What do the letters "cn" signify?

Thanks,

Bryan Brudevold

    Bryan,

    Please add the IMGLIB2.l64P library in your CCS project. The suffix "cn" refers to natural C code based functions while the other library is built using DSP specific intrinsics.

    The IMGLIB2.l64P must be used for obtaining optimized performance on the C64x+ DSP.

    FYI, An updated version of IMGLIB v3.x is now available on ti.com. It has CCSv4/v5 based projects and provides an eclipse plugin into the new CCS environment. If you wish you can update your IMGLIB version. Note the new library has a different suffix convention the library extensions are .a64p and ae64p refering to the COFF and ELF version of the library respectively.

    Regards,

    Rahul
