Abstract

In this paper the design and implementation of fused adder using novel carry generation unit is done. In this A and B are considered as inputs. In pre processing stages both propagator and generator signals are generated. Shifter will shift the signals and aligned in particular order. Carry propagation unit will propagate the carry and carry generation unit will generate the carry using GDI technique. At last in post processing stage output is generated. From results it can observe the comparison of total delay, logic delay and route delay for fused adder NCGU, PPA and RCA. Compared to those, entire fused adder NCGU reduces the delay in effective way.
