Hello

Is there any available documentation on the RTS Library (rts55.lib) for C55x DSP ?

Regards

    Hi

    Thanks for the answer.

    Ok there is some information about the lib in spru281g.pdf.

    Unfortunately, the information are only about how to use or recompile it.

    I am looking for documentations like a programmer's reference like this for fastRTS (spru653.pdf).

    Regards

    Cedric,

    Can you please help us understand your motivation to get more information on the RTS library. The TI C5000 Compiler is a pretty mature offering that has documentation included in the compiler installation. Additionally, the RTS library is provided in source for reference and to rebuild. 

    Beyond this if you need specific information on implementation of standard RTS libraries, I will need to move the post to our compiler forums. To help obtain this information , please share the RTS functions regarding which you need more information, so the compiler champs can provide this information

    Regards.

    Dear Rahul

    I work in an engineering school and we give some practical sessions with the DSP.

    We show to students the assembly code generated by the C compiler. Two functions are called (_mpyd and _addd) but they are not documented.

    That's why I ask if there is some documentation.

    Regards

    Cedric

    Those functions are called to perform floating point multiply and add.  They are not documented.  The source code for all of the RTS library, including these functions, is in the compiler package.  If you have CCS installed, a zip file is in a location similar to ...

    C:\ti\ccsv7\tools\compiler\c5500_4.4.1\lib\rtssrc.zip

    Search those files for the name of those functions.

    Thanks and regards,
