Take a look at "Computer Arithmetic - Principles, Architecture and Design"
by Kai Hwang. Chapter 8 is entitled "Convergence Division and Cellular
Array Dividers."
Also, if you take a look at the November issue of High Performance
Systems, there is an article called "Advancing the Standard" by Tom
Brightman of Cyrix Corp. He claims that Cyrix has a method for doing
"radix 128k" division and square root. This gives 17 bits per iteration
(note, this isn't per cycle). This method uses the multiply array.
