Abstract: Arithmetic Logic Unit (ALU) is a substantial fragment of microchip. Cutting-edge computerized processors, legitimate and math activity accomplishes making use of ALU. This paper depicts an 8-Bit ALU operating with a lowest power 11-Transistor Full Adder (11-T FA) and Gate dispersion input (GDI) centered MUX. All structures were simulated using Tanner EDA software version-15 with 32 nanometer BSIM4 innovation. Execution examinations were furnished as for voltage, power, postponement and power delay item. In this paper 8-bit ALU operated in subthreshold region, selected 0.7 VDD for maintain the both power as well as delay. In 8-bit ALU of GDI proposed model, less than 82% power consumption reduced as compare with CMOS 8-Bit ALU due to voltage level improvement.
Keywords: ALU (Arithmetic logic unit), FA (Full Adder), GDI (Gate diffusion input), MUX (Multiplexer)
Scope of the Article: Software Engineering Techniques and Production Perspectives.
