TMS320F2809: software FPU implementation - benchmark results

Part Number: TMS320F2809


I am having some difficulty finding code examples for software FPU implementation on the F2809 or equivalent. Do we have anything available? If so, do we have performance results?

Thank you!

    Do you mean routines that implement operations like floating point add?  The compiler RTS library includes such functions.  They are called by compiler generated code.  These routines are used to implement floating point operations on devices which do not have floating point math instructions.  You can find them in a directory similar to ...

    C:\ti\ccsv7\tools\compiler\ti-cgt-c2000_16.9.4.LTS\lib\src

    For example, the 32-bit add routine is in the file named fs_add28.asm.

    Unfortunately, I'm not aware of any.

    Thanks and regards,
