ABSTRACT:The digital India is playing an important role nowadays. Indian Vedas and Upanishads are also important and have a great history. That too Vedic mathematics was, is and will be an important basic logic for all mathematical related applications in various fields of science and technology. VLSI is an ever growing field which involves Analog, Digital and Mixed mode Designs. Also in VLSI research, an ALU is a very important system which involves user specifications while designing, for applications like microprocessor, microcontroller, signal processing and various fields. This paper concentrates on the related work on design of Vedic ALU, till date from 46 different IEEE papers and provides some common problem statements and solutions that can be used to design the best ALU, which is not done till date. Importance of reconfigurable feature is also explained in this paper.
