Thanks to all the responses !

I actually do have several math books that describe dividers. I
was trying to see if there was a clever (very small & fast) way
to build a 1/x function without pulling out my last gray hairs !

The end result would be to build a divider using a 1/x and then
multiply operations. The rational is that I already have a multi-
plier, and I was hoping to be able to build a 1/x function in much
smaller space and higher speed than a full divider.

I will post any finding I'll come across.

Cheers !
