Our volunteers share with the wider community their views and experiences on a variety of topics. The volunteers can range from associate editors to authors, reviewers or members from the research community at large. The interviews are intended to cover a wide spectrum of topics that are relevant to our community. These topics can be in the form of "shared experiences" and "lessons learned" or highlighting a new technological or theoretical breakthrough. We hope that members of the community will actively participate in making this new feature a great success. For information on submitting multimedia content, please click here.

Call for Papers: IEEE Transactions on Computers Special Section on Computer Arithmetic

Guest Editors Alberto Nannarelli, Peter-Michael Seidel, and Ping Tak Peter Tang [http://www.computer.org/portal/web/tc] seeking original manuscripts for the IEEE Transactions on Computers Special Section on Computer Arithmetic. Submission deadline: September 15, 2013.

 

Computer arithmetic is fundamental to the design of general-purpose and domain-specific processors. Novel arithmetic algorithms and hardware designs are needed to satisfy the power-performance requirements of numerically-intensive applications in a variety of areas including scientific computing, cryptography, multimedia, graphics and digital signal processing. Specialized number representations and encodings play a significant role in the design of arithmetic algorithms and their implementations. Additionally, understanding the fundamental properties of finite precision number systems is essential in the engineering of efficient arithmetic algorithms, as well as the current and future emerging technologies are important in influencing the design and the implementation of such algorithms.

An algorithmic and architectural study on Montgomery exponentiation in RNS

by Filippo Gandino, Fabrizio Lamberti, Gianluca Paravati, Jean Claude Bajard, Paolo Montuschi

 

The modular exponentiation on large numbers is a computationally intensive operation. An effective way for performing this operation consists in using Montgomery exponentiation in the Residue Number System (RNS). This paper presents an algorithmic and architectural study of such exponentiation approach. From the algorithmic point of view, the opportunities that come from the reorganization of the operations and the use of precomputation are considered. From the architectural perspective, the design opportunities offered by well-known computer arithmetic techniques are studied, with the aim of developing an efficient arithmetic cell architecture. Furthermore, since the use of efficient RNS bases with a low Hamming weight are being considered with ever more interest (as they are expected to be capable of reducing the overall computational effort, though at the cost of additional constraints on representable numbers), four additional cell architectures specifically tailored to these bases are developed and the trade-off between benefits and drawbacks is carefully explored. Based on the above developments, an overall comparison among all the considered algorithmic approaches and cell architectures is presented, with the aim of providing the reader with an extensive overview of the Montgomery exponentiation opportunities in RNS.
