Can you do me a favor and talk about fix_ed_point arithmetic/optimizations?
Because fixpoint has a totaly different meaning mathematically[1].
Especially when talking about transformation operators in video coding.

To me it's highly confusing and i need each time a second to realize
that you talk about fixedpoint arithmetic instead of arithmetics related
to the fixpoint.

Thanks a lot
