Daftar Isi: Design and Implementation of an Optimum VLSI Based 16-BIT ALU

Daftar Isi:

The three most important performance parameters for a VLSI design are logic delay, chip area and power consumption. In this paper, The VLSI design of a 16-bit ALU is described, and it is optimised in terms of speed, power consumption, and chip area. Various logic families have been implemented the development of various logic modules used in the design of a 16 BIT ALU. For each module, the selection of the logic family depends on the factors such as speed and power consumption provided by the specific logic family. The most significant aspect in the arithmetic operations of an ALU is the adder circuit. A detailed analysis of the different available adder circuit configurations is carried out in this research paper and the best fitted one is selected for the design of the required ALU. Carry Skip Adder is utilised to create the best ALU. By the end of this paper, a 16-bit ALU will be developed which will be portraying various logic families like CMOS for basic operations and pseudo-NMOS for advanced logic families.
