Advanced arithmetic for the digital computer - design of arithmetic units

Feel lonely? What about reading books? Book is one of the greatest friends to accompany while in your lonely time. When you have no friends and activities somewhere and sometimes, reading book can be a great choice. This is not only for spending the time, it will increase the knowledge. Of course the b=benefits to take will relate to what kind of book that you are reading. And now, we will conc...

Design of Long Integer Arithmetic Units for Public-Key Algorithms

For many years the terms RSA and Public-Key Cryptography were used more or less synonymously. Consequently, long integer arithmetic units for public-key cryptography were designed to support mainly this specific algorithm. Today, however, the requirements on such an arithmetic unit have changed and are much harder to fulfil than in the past. This is due to growing interest in new public-key alg...

VHDL Library of Arithmetic Units

A comprehensive library of arithmetic units written in synthesizable VHDL code has been developed. The library contains components for a variety of arithmetic operations and for different speed requirements. The library components are implemented as circuit generators in parameterized structural VHDL code. Their modular and well-documented source code allows for simple usage and easy customizat...

Design and Implementation of Three Dimensional Arithmetic Units

We describe the design and the implementation of two three dimensional arithmetic units: a 3D adder and a 3D multiplier. Compared to their 2D counterparts, our 3D adder incurs 10.6–34.3% less delay and 11.0–46.1% less energy when the width increases from 12-bit to 72-bit; the 32×32 3D multiplier incurs 14.4% less delay and 6.8% less energy, according to the post place and route results. The pro...
