  • Minor cleanup

Reference model

  • Add support for checking against a provided TOSA level
  • Update test generators to handle the EIGHTK TOSA level
  • Add a precise mode which calculates operators in FP64 precision to work with Main inference floating-point conformance testing

Thanks for the new update!

Is there a place where we can see a more formal diff (e.g. git diff?) of the specification to make sure that we really catch also small changes?

I had a whole writeup of how I couldn’t do this, but then just before pressing reply I think I have the right way to do this with cgit. This should give you the 0.60.0 to 0.70.0 diff for the specification:

https://git.mlplatform.org/tosa/specification.git/diff?id=v0.60.0&id2=v0.70.0

You will see that a lot of the changes are the XML cleanup to be more consistent/organized with arguments to the operators.
