Energy-aware analysis of electrically long high speed I/O links
This paper presents a novel approach for an energy-aware analysis of electrically long high speed I/O links. ABCD-parameters are used to analyze the passive link model, which takes into account termination impedances at transmitter and receiver as well as the network parameters of the interconnect. Voltage transfer function and input impedance of the link model are used to carry out a combined evaluation of frequency dependent signal transmission and power consumption of the link. The combined analysis allows to carry out an optimization of the energy efficiency under the given constraints. It is applied to a realistic high speed backplane link, which is modeled using measured interconnect network parameters. Simulated interconnect network parameters are used to study the impact of link improvements on signal transmission and power consumption. © 2012 Springer-Verlag.
