ALU is a combinational device which performs arithmetic and logical operations. It plays an important role in most of the existing commercial processors. The power consumption and area of a processor settle on the structure of an ALU. There are two structures of an ALU one is tree and another one chain. This paper is to design and implementation of 32-bit ALU with chain structure. With this structure the authors are reducing the overall delay and area of an ALU by repositioning functional components based on the frequency of an operation within the specific application.
