Adders are the basic building blocks of any processor or data path application. In adder design, carry generation is the critical path. To reduce the power consumption of the data path, we need to reduce the area of the adder. Carry Select Adder is one of the fast adders used in may data path applications. The proposed design is implemented without using multiplexer and RCA structure with Cin=1. Instead of using multiplexer and RCA Cin=1 structure, we use simple combinational circuit. After speed, power dissipation is one of the most important design objectives in integrated circuits. As adders are the most widely used components in such circuits, the design of efficient adder is of much concern for researchers. This study presents a performance analysis of different Fast Adders. The comparison is done on the basis of three performance parameters, i.e. Area, Speed and Power consumption. We also show a modified carry select adder designed at different stages.

The two volumes of this book collect high-quality peer-reviewed research papers presented in the International Conference on ICT for Sustainable Development (ICT4SD 2015) held at Ahmedabad, India during 3 – 4 July 2015. The book discusses all areas of Information and Communication Technologies and its applications in field for engineering and management. The main focus of the volumes are on applications of ICT for Infrastructure, e-Governance, and contemporary technologies advancements on Data Mining, Security, Computer Graphics, etc. The objective of this International Conference is to provide an opportunity for the researchers, academicians, industry persons and students to interact and exchange ideas, experience and expertise in the current trend and strategies for Information and Communication Technologies.

The International Workshop on Power and Timing Modeling, Optimization, and Simulation PATMOS 2002, was the 12th in a series of international workshops 1 previously held in several places in Europe. PATMOS has over the years evolved into a well-established and outstanding series of open European events on power and timing aspects of integrated circuit design. The increased interest, espe- ally in low-power design, has added further momentum to the interest in this workshop. Despite its growth, the workshop can still be considered as a very - cused conference, featuring high-level scienti?c presentations together with open discussions in a free and easy environment. This year, the workshop has been opened to both regular papers and poster presentations. The increasing number of worldwide high-quality submissions is a measure of the global interest of the international scienti?c community in the topics covered by PATMOS. The objective of this workshop is to provide a forum to discuss and inves- gate the emerging problems in the design methodologies and CAD-tools for the new generation of IC technologies. A major emphasis of the technical program is on speed and low-power aspects with particular regard to modeling, char- terization, design, and architectures. The technical program of PATMOS 2002 included nine sessions dedicated to most important and current topics on power and timing modeling, optimization, and simulation. The three invited talks try to give a global overview of the issues in low-power and/or high-performance circuit design.

The proceedings from the June 2001 conference in Vail, Colorado, feature 30 papers on binary strings, multiplication and exponentiation, cryptography, division and square root, elementary functions and rounding, number systems, floating high points, addition, logarithmic number systems, and on-line arithmetic. An abstract of the keynote speech offers a processor architect's perspective on computer arithmetic. And a reprint of Knowles's "A Family of Adders," which was mis-printed in the proceedings from the previous conference, is included. Contributors represent 11 countries. Name index only. c.
