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.

Variability-Aware Task Allocation for Energy-Efficient Quality of Service Provisioning in Embedded Streaming Multimedia Applications

by Francesco Paterna, Andrea Acquaviva, Alberto Caprara, Francesco Papariello, Giuseppe Desoli, and Luca Benini

 

Multimedia streaming applications running on next-generation parallel multiprocessor arrays in sub-45nm technology face new challenges related to device and process variability, leading to performance and power variations across the cores. In this context, Quality of Service (QoS), as well as energy efficiency, could be severely impacted by variability. In this work we propose a run-time variability-aware workload distribution technique for enhancing real-time predictability and energy efficiency based on an innovative Linear-Programming + Bin-Packing formulation which can be solved in linear time. We demonstrate our approach on the virtual prototype of a next-generation industrial multi-core platform running representative multimedia applications. Experimental results confirm that our technique compensates variability, while improving energy-efficiency and minimizing deadline violations in presence of performance and power variations across the cores. The proposed policy can save up to 33% of energy with respect to the state-of-the-art policies and 65% of energy with respect to one variability-un-aware task allocation policy while providing better QoS.
