The objective of this thesis is to describe the design and
implementation of a VSLI reduced instruction set computer (RISC).
The RISC machine constitutes a new style of computer architecture.
It differs significantly from the complex instruction set computer
architectures (CISC) of the past. RISC architectures are
characterized by their...
In the past, multimedia technology focused mainly on designing high quality audio and graphical imagery as well as providing adequate performance levels that the users demand for multimedia applications. However, the concept of multimedia has expanded into New-Media that involves variety use of multimedia data in consumer-oriented applications, such as...
The multimedia capabilities of computers have recently become the focus of computer developers due to the increasing demand for advanced computer graphics and new media capabilities, such as video conferencing, 3-D visualization, and animation. To support these multimedia capabilities, specialized graphics hardware, such as MPEG encoding/decoding card, 3-D graphics card,...
Sorting is typically a compute intensive operation used in many
areas of industry. With improved technology, both in the VLSI and CAE
areas, we can afford to develop hardware based database computers to
move the work load off the main computer. In this thesis the
architecture of a VLSI parallel...
The objective of this thesis is to present the architecture and
design of a neural network-based pattern classifier. The classifier
detects textual characters which have been translated, rotated, and
corrupted by noise. This form of pattern classifier differs
significantly from traditional pattern classifiers. The neural network
architecture used in implementing...
This thesis is concerned with the development of a unique
parallel sort-merge system suitable for implementation in VLSI.
Two new sorting subsystems, a high performance VLSI sorter and a
four-way merger, were also realized during the development
process. In addition, the analysis of several existing parallel sorting
architectures and algorithms...
In microwave network analysis, proper matching of the measurement system is necessary to prevent measurement errors and provide a
proper terminating impedance for the device-under-test. To obtain
this matching, a buffer amplifier is often used in the first stage of
the network analyzer.
This study describes the design and analysis...
A relatively new development in the electric machines field has been the written-pole technology, of which the latest product is the large single-phase electric motor, the single phase Written-Pole Motor (WPM). The WPM is a synchronous, permanent-magnet single-phase motor having a weak rotor cage for start-up which in addition exhibits...
Team pursuit-evasion games are studied here with one performance
index for the team as a unit in competition with one common opponent.
Particular structures of team games are discussed after a brief introduction
of the two-player differential games. The classical calculus
of variations is used to derive the feedback strategies...
This thesis discusses a special type of a versatile, distributed control system, the Taskmaster II. It includes a detailed specification of a readily realizable Taskmaster system utilizing a layered communication among units, oriented on the ISO OSI seven layer model. The specification was developed from the analysis of previous research...
The advent of superior power semiconductor devices and converter topologies
has renewed interest in ac drive systems. Although considerable research efforts have
gone into improving power electronic converter devices and topologies, very little has
been reported on the overall performance optimization of induction machine drive
systems. The report of the...
Advances in VLSI array processing have led to many new
parallel structures for real-time Digital Signal Processing (DSP)
applications. Among all the architectures, systolic arrays have played
an important role because systolic arrays have regular, local
interconnections with modular structure. In ordinary systolic arrays,
however, all processing operations and data...
The problem of synchronization arises in the interaction among
digital systems not sharing a common clock reference. The reliability of synchronizers is related to metastable operation of
bistable elements. Because of its subtle nature, the phenomenon
until recently was not widely researched. However, the literature
now contains a sound theoretical...
An analytical expression is derived which allows the
bulk minority carrier recombination lifetime, t, and the
surface recombination velocity, S, to be extracted from a
single noncontact photoconductivity decay (PCD) measurement. This analytical expression is rather complex, but
can be reduced to a first order approximation. The first
order approximation...
Substrate switching noise is becoming a concern as integrated circuits get larger and speeds get faster. Mixed-mode integrated circuits are especially affected as the substrate noise interferes with sensitive analog circuits resulting in limited signal to noise ratios. This thesis serves to study the cause of the noise at the...
An EMCON-D distributed process controller is evaluated
for control and monitoring of an experimental doubly-fed
machine system. A closed-loop control circuit is
implemented to operate the doubly-fed machine with
constant rotor current. A standard PID algorithm as well
as an algorithm tailored to the doubly-fed machine are
evaluated.
A scalable macromodel for substrate noise coupling in lightly doped substrates with and without a buried layer has been developed. This model is based on Z-parameters and is scalable with contact size and separation. This model requires process dependent parameters that can be extracted easily from a small number of...
