floating point characterization

Dear freescalers,

I was looking for documents that help to understand and characterize the floating point support for 8-bit microcontrollers of the family HC(S)08.

I found this nice one for family HC11: AN974 floating-point Package. I was wondering if anything similiar for HC(S)08 microcontrollers have been written.

I need it since I would like to evaluate the worst case when I'm using the floating point implementation of some algorithm. In the forum I've read that a floating point sum/multiplication can take some thousend time the execution time of an integer one, hovever I need a more accurate estimation.

Thank you very much
