Transactions on Computers Media Center

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.

QCA Systolic Array Design

by Liang Lu, Weiqiang Liu, Maire O’Neill, Earl E. Swartzlander Jr.

 

Quantum-dot Cellular Automata (QCA) technology is a promising potential alternative to CMOS technology. To explore the characteristics of QCA and suitable design methodologies, digital circuit design approaches have been investigated. Due to the inherent wire delay in QCA, pipelined architectures appear to be a particularly suitable design technique. Also, because of the pipeline nature of QCA technology, it is not suitable for complicated control system design. Systolic arrays take advantage of pipelining, parallelism and simple local control. Therefore, an investigation into these architectures in semi-conductor QCA technology is provided in this paper. Two case studies, (a matrix multiplier and a Galois Field multiplier) are designed and analyzed based on both multilayer and coplanar crossings. The performance of these two types of interconnections are compared and it is found that even though coplanar crossings are currently more practical, they tend to occupy a larger design area and incur slightly more delay. A general semi-conductor QCA systolic array design methodology is also proposed. It is found that by applying a systolic array structure in QCA design, significant benefits can be achieved particularly with large systolic arrays, even more so than when applied in CMOS-based technology. This research work will lead the way for the design of more complex QCA circuits allowing researchers to develop new QCA design methodologies and demonstrate the full potential of QCA nanotechnology.
