The Mechanism of The Arithmetic Logic Unit

The Arithmetic Logic Unit is widely used in electrical components nowadays such as the CPU in computers. The traditional research is based on the theory of a combination of multiple logic units, the results are not performed intuitional. This paper provides an introduction to the Arithmetic Logic Unit and its mechanisms, which consist of multiple logic gates to perform binary operations and send commands to the computer. The article discusses binary operations using logic gates, starting from the simplest one-bit half-adder to the more complex four-bit ALU, encompassing functions like addition, subtraction, division, and multiplication. The simulation module is used to justify the mechanism of the ALU. This research provides a new method in the process of developing the ALU, may largely increases the productivity. The approach may be used in the research and development of computer performance, providing visual, instant feedback and reducing the cost.
