Anish (02EC3014) 2 ACKNOWLEDGEMENTS It is with great reverence that we wish to express our deep gratitude towards our VLSI Engineering Professor and Faculty Advisor, Prof. Sw apna Banerjee , Department of Electronics & Electrical Communication, Indian Institute of Technology Kharagpur, under whose supervision we completed our work. Her astute guidance, invaluable suggestions, enlightening comments and constructive criticism always kept our spirits up during our work. We would be accused of ingratitude if we failed to mention the consistent encouragement and help extended by Mr. Kailash Chandra Ray, Graduate Research Assistant, during our Term-Project work. The brainstorming sessions at AVDL spent discussing various possible architectures for the FFT were very educative for us novice VLSI students. Our experience in working together has been wonderful. We hope that the knowledge, practical and theoretical, that we have gained through this term project will help us in our future endeavours in the field of VLSI.
