Non-restoring division algorithm

Question

Does anyone know the steps for dividing unsigned binary integers using non-restoring division?

It\'s hard to find any good sources online.

i.e if A = 10111

Answer 1

(My answer is a little late-reply. But I hope it will be useful for future visitors)

Algorithm for Non-restoring division is given in below image :

In this problem, Dividend (A) = 101110, ie 46, and Divisor (B) = 010111, ie 23.

Initialization :

Set Register A = Dividend = 000000
Set Register Q = Dividend = 101110
( So AQ = 000000 101110 , Q0 = LSB of Q = 0 )
Set M = Divisor = 010111, M' = 2's complement of M = 101001
Set Count = 6, since 6 digits operation is being done here.

After this we start the algorithm, which I have shown in a table below :

In table, SHL(AQ) denotes shift left AQ by one position leaving Q0 blank.

Similarly, a square symbol in Q0 position denote, it is to be calculated later

Hope all the steps are clear from the table !!!
