Abstract: Power dissipation is the most important issues faced all the designers in modern science. Moreover, a clock pulse is a main reason of power consumption in digital design. Moreover, clock gating method in structure stage can be executed to decrease dynamic power. This study aim to design, implement and compare the various resources consumption utilizing clock gating techniques in 16 bit ALU design. The two clock signals proposed and used in the normal ALU design. Which supply the clock signal for one block only either logical or arithmetic block, while the other is switch OFF. With the purpose of executing arithmetic and logic architecture, 130 nm standard cell technology libraries are employed to realize the implementation. In addition, the simulations are compiled by using the Modelsim Software. Verilog Hardware Description Language (HDL) models is verified the construction of arithmetic and logic process. Similarly, it carried out with Quartus II 14.1 web edition (64 bit). This technique leads to the reduction in dynamic power consumption using AND based clock gating up to 32.88%. Therefore, the proposed design is acceptable to usage in the system to optimize power consumption in modern devices.
