This paper presents an energy efficient ALU using magnitude comparator designed in GDI(gate diffusion input) technique. The proposed GDI magnitude comparator used ALU has been compared with existing design technologies such as CMOS, Transmission gate logic (TG) and pass transistor logic (PTL). The performance analysis of comparator designed using this technologies is done on the basis of power consumption ,delay and number of transistors using Cadence virtuoso tool and found to be efficient. Based on the performance of GDI comparator in ALU, all blocks of ALU is designed using GDI technology. The simulation results of GDI ALU have shown remarkable performance in terms of power consumption, delay & number of transistors compared to ALU designed using CMOS, TG & PTL. But this GDI ALU suffers from some practical limitation like swing degradation. This limitation can be overcome by modified GDI ALU. Thus proposed GDI ALU can be a viable option for low power application.
