PIM-SM (Protocol Independent Multicast - Sparse Mode) is a multicast routing protocol that uses one central node (which we refer to with the Rendezvous Point ??RP??) for all transmitters in a multicast group. It builds source-specific trees to the transmitters whose data rates exceed a predefined threshold. Investigations have been done to improve and provide an efficient mechanism for switching between...
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...
This paper presents an analytical modeling of ballistic and quasi-ballistic transport, implemented in Verilog-A environment and used for circuit simulation. Our model is based on the Lundstrompsilas approach and uses an expression of the backscattering coefficient given by the flux method. The model takes also into account short channel effects and tales into account the effects of different scattering...
A physical yet analytical phase change memory (PCM) model simultaneously accounting for thermal and electrical conductivities is presented. Due to the physics based nature of the model, the essential temperature from heating and cooling of PCM during operation is instantaneously updated. More importantly, the model can be applied to non-conventional circuit design technique. We show that for the first...
We designed and built a novel all-optical re-timing, re-amplifying, and re-shaping (3R) regeneration system based on terahertz optical asymmetric demultiplexers (TOADs) developed in our laboratory. The system is capable of parallel processing multiple wavelengths, a feature which will significantly improve the scalability of current wavelength division multiplexing (WDM) networks. Performance against...
