Based on the impact of the scattering effect on latency and bandwidth, this letter presents the quality-factor model that optimizes latency and bandwidth effectively with consideration of the scattering effect. Then, we get the optimization analytical model with target interconnect linewidth and line spacing by the curve-fitting method. The proposed model has been verified and compared for nanoscale...
High-speed optical circuit-switched networks are being deployed to support highly demanding applications in the eScience research community. File transfers were identified as an ideal application for high-speed circuits because such transfers can utilize any rate, limited only by end-host capabilities. This paper addresses the question of how a circuit-switched network can be shared efficiently amongst...
Current mode (CM) scheme provides suitable alternative for the high speed on-chip interconnect signaling. This paper presents a energy-delay optimization methodology for the current-mode (CM) signaling scheme. Optimization for the CM circuits for on-chip interconnects requires a joint optimization of driver and receiver device sizes, as their parameters which affect the energy-delay performance depend...
We present a generic method for analyzing the effect of process variability in nanoscale circuits. The proposed framework uses kernel and a generic tail probability estimator to eliminate the need for a-priori density choice for the nature of circuit variation. This allows capturing the true nature of the circuit variation from a few random samples of its observed responses. The data-driven, non-parametric,...
In this paper, we study bandwidth management of a wireless/optical based access/metro network in support of voice and data services. For voice services, we use a finite state Markov Chain to estimate the blocking probability of voice circuits over an Adaptive modulation and coding wireless channel, as a function of the channel parameters. For data services, we evaluate a rate matching and a buffer...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
