3d-Softchip: A Novel 3d Vertically Integrated Adaptive Computing System [Thesis], Chul Kim
3d-Softchip: A Novel 3d Vertically Integrated Adaptive Computing System [Thesis], Chul Kim
Theses: Doctorates and Masters
At present, as we enter the nano and giga-scaled integrated-circuit era, there are many system design challenges which must be overcome to resolve problems in current systems. The incredibly increased nonrecurring engineering (NRE) cost, abruptly shortened Time-to- Market (ITA) period and ever widening design productive gaps are good examples illustrating the problems in current systems. To cope with these problems, the concept of an Adaptive Computing System is becoming a critical technology for next generation computing systems. The other big problem is an explosion in the interconnection wire requirements in standard planar technology resulting from the very high data-bandwidth requirements …

Opto-Vlsi Based Wdm Multifunction Device, Selam T. Ahderom
Theses: Doctorates and Masters
The tremendous expansion of telecommunication services in the past decade, in part due to the growth of the Internet, has made the development of high-bandwidth optical net-works a focus of research interest. The implementation of Dense-Wavelength Division Multiplexing (DWDM) optical fiber transmission systems has the potential to meet this demand. However, crucial components of DWDM networks – add/drop multiplexers, filters, gain equalizers as well as interconnects between optical channels – are currently not implemented as dynamically reconfigurable devices. Electronic cross-connects, the traditional solution to the reconfigurable optical networks, are increasingly not feasible due to the rapidly increasing bandwidth of the …

Adaptive Applications Of Opto-Vlsi Processors In Wdm Networks, Mehrdad Raisi
Theses: Doctorates and Masters
Communication is an inseparable part of human life and its nature continues to evolve and improve. The advent of laser was a herald to the new possibilities in the communication world. In recent years technologies such as Wavelength Division Multiplexing (WDM) and Erbium Doped Fiber Amplifiers (EDFA) have afforded significant boost to the practice of optical communication. At the heart of this brave new world is the need to dynamically/ adaptively steer/route beams of light carrying very large amounts of data. In recent years many techniques have been proposed for this purpose by various researchers. In this study we have …

Implementation Of Arithmetic Primitives Using Truly Deep Submicron Technology (Tdst), Sholeh Eshraghian
Theses: Doctorates and Masters
The invention of the transistor in 1947 at Bell Laboratories revolutionised the electronics industry and created a powerful platform for emergence of new industries. The quest to increase the number of devices per chip over the last four decades has resulted in rapid transition from Small-Scale-Integration (SSI) and Large-Scale-lntegration (LSI), through to the Very-Large-Scale-Integration (VLSI) technologies, incorporating approximately 10 to 100 million devices per chip. The next phase in this evolution is the Ultra-Large-Scale-Integration (ULSI) aiming to realise new application domains currently not accessible to CMOS technology. Although technology is continuously evolving to produce smaller systems with minimised power dissipation, …
Intelligent Approaches To Vlsi Routing, Maolin Tang
Intelligent Approaches To Vlsi Routing, Maolin Tang
Theses: Doctorates and Masters
Very Large Scale Integrated-circuit (VLSI) routing involves many large-size and complex problems and most of them have been shown to be NP-hard or NP-complete. As a result, conventional approaches, which have been successfully used to handle relatively small-size routing problems, are not suitable to be used in tackling large-size routing problems because they lead to 'combinatorial explosion' in search space. Hence, there is a need for exploring more efficient routing approaches to be incorporated into today's VLSI routing system. This thesis strives to use intelligent approaches, including symbolic intelligence and computational intelligence, to solve three VLSI routing problems: Three-Dimensional (3-D) …
