Pointers requested on 2's complement non-restoring divider

Hi!
Does anybody know where I can find out about implementing : 2's complement
divider with non-restoring
algorithm (and in VHDL)?
I'm not a computer science student, but have an assignment along these
lines. Have tried reading through some comp/arith books by Parhami / Berhooz
/ Koren but much of the content is above my head. Any serious advice
welcomed!
TIA, Rgds Chris
