A new high radix non-restoring divider architecture
A.E. Bashagha, M.K. Ibrahim · International Journal of Electronics · 1995
This paper presents a new radix-2k non-restoring area-efficient fast divider architecture where k quotient bits (one digit) are calculated in one step. Unlike the existing non-redundant high radix architecture, the proposed architecture makes use only of the odd multiple values of the divisor. Therefore, it requires nearly half the area of the existing one. The input operands are in the two's complement form, whereas the output quotient is in their's complement form. This architecture is general for any value of k and can deal with positive and negative operands. Any adder can be used in the basic cell. This can be a ripple carry adder or a carry lookahead adder.
