24. Synthesis and Optimization of Threshold Logic Networks with Application to Nanotechnologies.

Author

Lauwereins, Rudy, Madsen, Jan, Rui Zhang, Gupta, Pallav, Lin Zhong, and Jha, Niraj K.

Abstract

We propose an algorithm for efficient threshold network synthesis of arbitrary multi-output Boolean functions. The main purpose of this work is to bridge the wide gap that currently exists between research on the development of nanoscale devices and research on the development of synthesis methodologies to generate optimized networks utilizing these devices. Many nanotechnologies, such as resonant tunneling diodes (RTD) and quantum cellular automata (QCA), are capable of implementing threshold logic. While functionally correct threshold gates have been successfully demonstrated, there exists no methodology or design automation tool for general multi-level threshold network synthesis. We have built the first such tool, ThrEshold Logic Synthesizer (TELS), on top of an existing Boolean logic synthesis tool. Experiments with about 60 multi-output benchmarks were performed, though the results of only 10 of them are reported in this paper because of space restrictions. They indicate that up to 77% reduction in gate count is possible when utilizing threshold logic, with an average reduction being 52%, compared to traditional logic synthesis. Furthermore, the synthesized networks are well-balanced, and hence delay-optimized. [ABSTRACT FROM AUTHOR]

25. Energy Aware Multimedia Messaging Services Across Networks and Across Devices for Mobile Users.

Author

Xiuzhen Cheng, Wei Li, Znati, Taieb, Bin Wei, and Lin Zhong

Abstract

The extensive coverage of wireless networks brings tremendous opportunities for messaging services to satisfy the demands of accessing multimedia and time-critical information from mobile users. This trend makes energy efficiency an increasing challenge on mobile devices. In this paper, we propose a novel solution toward meeting this challenge. We explore communications utilities along both "cross-network" and "cross-device" dimensions for managing multimedia messaging services. Along the cross-network dimension, we consider the multitude of networking capabilities at a mobile terminal and select the most energy-efficient communication medium to maintain the connectivity or accomplish data transfer. Along the cross-device dimension, we consider the multitude of user interface devices by which mobile users can further improve overall energy efficiency in consuming multimedia messages. In this writing, we discuss our method as a position paper. Related experiments were performed and results are presented to justify our approach. Keywords:energy aware, energy efficiency, and multimedia messaging system. [ABSTRACT FROM AUTHOR]
