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.

Analysis of Error Masking and Restoring Properties of Sequential Circuits

by Jinghang Liang, Jie Han, and Fabrizio Lombardi

 

Scaling of CMOS technology into nanometric feature sizes has raised concerns for the reliable operation of logic circuits such as in the presence of soft errors. This paper deals with the analysis of the operation of sequential circuits. As the feedback signals in a sequential circuit can be logically masked by specific combinations of primary inputs, the cumulative effects of soft errors can be eliminated. This phenomenon, referred to as error masking, is related to the presence of so-called restoring inputs and/or the consecutive presence of specific inputs in multiple clock cycles (equivalent to a synchronizing sequence in switching theory). In this paper, error masking is extensively analyzed using the operations of state transition matrices (STMs) and binary decision diagrams (BDDs) of a finite state machine (FSM) model. The characteristics of the state transitions with respect to the correlation between the restoring inputs and the time sequence are mathematically established using STMs; although the applicability of the STM analysis is restricted due to its complexity, the BDD approach is more efficient and scalable for use in the analysis of large circuits. These results are supported by simulations of benchmark circuits and may provide a basis for further devising efficient and robust implementation when designing FSMs.
