BRENT KUNG ADDER

 

The Brent Kungs adder works on the principle of O operator. The O operator is defined as (gx , px) O (gy , py) = (gx + px . gy , px. py) = (Gxy , Pxy). And if y = 0, then (Gx0, Px0) = (Gx , Px).

 

Let (Gi , Pi ) = (g0 , p0 ) if i=0

= (gi , pi) O ( Gi-1 , Pi-1) if 1≤ i ≤ n-1 (3.12)

 

Then ci = Gi for i=0,1, 2,3..n-1 . (3.13)

 

Let m = (gm , pm ) and ji = (Gji , Pji )= (gj , pj ) O (gj-1 , pj-1 ) O..O (gi , pi )

 

Lemma2. The operator O is associative i.e. 31= (3 ) O (21 ) = ( 32 ) O (1)

The resultant 16 bit carry generation topologies are given below. In Brent-Kung adders the significance of black and white processors are given in Fig. 4 and delay and power calculation (using standard 90nm CMOS technology)
