Fluctuations in one system affect adjacent systems; mechanistic understanding of linkages helps conservation efforts be more effective by focusing on influential species and areas that facilitate connections between ecosystems. This study explored marine-derived nutrient inputs to adjacent terrestrial communities. We quantified wrack (seaweed and other organic matter) deposition at sites...
Computers using the tagged-token dataflow model are among the best candidates for delivering extremely high levels of performance required in the future. Instruction scheduling in these computers is determined by associatively matching data-bearing tokens in a Waiting-Matching Unit (W-M unit). At the W-M unit, incoming tokens with matching contexts are...
To understand the forces exerted on structures during tsunamis, model cities are subjected to human-generated tsunamis. The study of vertical evacuation, wherein individuals could take refuge in the upper levels of strong buildings, has resulted in a growing need for a low cost wireless acceleration data logger. Such a device...
In the continuing effort to reduce time spent in the product development cycle many industries
have realized the benefits of rapid prototyping. Within a few hours a design engineer can turn a
computer model into an actual three-dimensional object allowing customers, engineers and
marketing agents to evaluate a product early...
This project is a custom output stage for a two-channel signal source design project at Oregon State. Starting in January, I began leading a team tasked with the development of an arbitrary waveform generator via the CreateIT Collaboratory at OSU. Undergraduate students interview into the CreateIT Collaboratory and are assigned...
Efficient methods for simulating the substrate noise generated by complex synchronous and asynchronous digital logic circuits are presented. By simulating digital logic at the gate level, and precharacterizing the gates, the substrate noise generation can be predicted and used in a transistor level simulation of the sensitive analog blocks. This...
The AE32000 processor core, developed by Advanced Digital Chips Inc., Korea, is used primarily in the embedded processing environment. The AE32000 simulator models this embedded processor core having high code density. An enhanced simulator was developed to study the performance of the present Instruction Set Architecture after comparison with the...
A method for improving performance/watt of an embedded single-instruction multiple-data (SIMD) architecture using application-guided a priori scheduling of hardware resources is presented. A multi-core architectural simulator is adopted that accurately estimates power, performance, and utilization of various processor components (logic, interconnect and memory). A greedy search is then performed on...
AE32000 microprocessor was developed mainly to address the need for the reduction in the amount of memory accesses in embedded applications. One of the primary goals of a computer architect is the design and construction of machines, that support the efficient execution of the programs that will run on them....
In this comprehensive thesis, we present a series of experiments and findings that highlight the
critical importance of TDC Voltage Sensors in the hardware security domain. Our research begins
by introducing a novel self-calibrating module, demonstrating its efficiency through preliminary
calibration tests. We then delve into the Peak-to-Peak tests, which...
