Got any good reads on floating point math design?
I saw a particularly efficient VHDL implementation in the mrisc32-a1, though this is lacking support for rounding modes. Together with the rest of the processor this is a very interesting project, I hope that the author progresses it further.

Floating point unit in systemc
In my VHDL implementation I use the same iterative divider for integer and for floating-point: https://github.com/mrisc32/mrisc32-a1/blob/master/rtl/muldiv/div_impl.vhd
