DSPLIB : no Big Endian assembly-optimized DSPLIB available for c67

Hie

I'm looking for an assembly-optimized fft for my c6713 dsp but I'm quite surpised to see that Texas proposes this for :

  • c64x Little endian 
  • c64x Big Endian
  • c67x Little Endian


Why there is no c67x Big Endian DSPlib  ???

Thanks if anybody has a link to the DSPLIB for c6713 in Big-endian.

    Hi Hubert,

    No. It is not available.

    Just went to the C6713 product webpage and downloaded the "TMS320C67x DSP Library" (  ), installed and had a look at the document, "SPRU657B.pdf" under docs folder.

    It is specified that most of the library functions were little endian, few were neutral. There are two functions provided for swapping the 16 bit values and 32 bit values from big endian to little endian and vice versa.

    And, on the whole, I do not see any Big endian support availability for C67xDSPLIB

    Hi,

    Thanks for your post.

    For Big Endian:

    TMS320C64x+ DSP Big-Endian Library Programmer's Reference documentation at:

    http://www.ti.com/lit/spruec5

    SPRC263 is the latest version of the C64x+ BEDSPLIB and you could download at:

    http://focus.ti.com/docs/toolsw/folders/print/sprc263.html (but unfortunately, this page is not available currently).

    May be, you could try download c67x DSPlib (sprc121) @ the below link:

    http://focus.ti.com/docs/toolsw/folders/print/sprc265.html

    Thanks & regards,

    Sivaraj K
