Wireless networks-on-chips (WINoCs) hold substantial promise for enhancing multicore integrated circuit performance, by augmenting conventional wired interconnects. As the number of cores per IC grows, intercore communication requirements will also grow, and WINoCs can be used to both save power and reduce latency. In this article, we briefly describe some of the key challenges with WINoC implementation, and also describe our example design, iWISE, which is a scalable wireless interconnect design. We show that the integration of wireless interconnects with wired interconnects in NoCs can reduce overall network power by 34 percent while achieving a speedup of 2.54 on real …


Design And Simulation Of Interconnected H-Bridge Inverter, Samuel Muehleck Jun 2012

Design And Simulation Of Interconnected H-Bridge Inverter, Samuel Muehleck

Computer Engineering

In this project, the research, design and simulation of an interconnected H-bridge single-phase inverter was explored. The inverter design was divided into three separate sections. First, a VHDL programmed CPLD was used to generate control signals for the transistors of the inverter circuit. Second, power electronics was used to create an inverter circuit to change a DC input to a 60 Hz AC output. Lastly, additional circuits were used to link the generated control signals to the MOSFET transistors of the inverter circuit. The operation of the three components was then validated with computer simulations. Results of computer simulation demonstrate …

Riley The Cat, Nicholas Zankich

Computer Engineering

There are many toys that exist that are comfort objects. Generally these are toys that are soft such as blankets, stuffed animals, and pillows. Robotic toys also exist such as games, interactive books, and instruments. There exists a crossover market that includes Furbys, Tomagachi pets, and Fur Real Friends. While being very popular, I believe that this crossover isn’t perfect, and that there is a lot of room for improvement. Riley (Figure 1) was created to make something that is both completely a robot and a comfort object.


Iphone Breathalyzer: Point Oh Wait!, Gurpal Bhoot Jun 2012

Iphone Breathalyzer: Point Oh Wait!, Gurpal Bhoot

Electrical Engineering

This final year project combines hardware and software components to create an alcohol breathalyzer that is compatible with the iPhone. The final design of the circuit and the iPhone application is original and combines multiple components to create the final product. Most of those components are seen in a simplified version of a breathalyzer, while the added components take care of the interface to the iPhone.

Bluemote!, Philip Kaye

Computer Engineering

In today’s society, our mobile phones are an extremely useful device when we are on the go and away from our homes; however, when we return home, our smart phone becomes just a communication tool again. Home automation is inevitable, and it will find its way into every house. The first person to commercialize it to the point where it is as easy to set-up and as affordable as a home router will end up breaking this slow trend. The key to this success is the smart phone; this should end up being the most expensive piece of hardware for …


Measurement And Modeling Of Passive Surface Mount Devices On Fr4 Substrates, Rahulkumar Sadanand Koche Jan 2012

Measurement And Modeling Of Passive Surface Mount Devices On Fr4 Substrates, Rahulkumar Sadanand Koche

Dissertations and Theses

Passive components like resistors, capacitors and inductors are used in every electronic system. These are the very basic components which affect the system performance at higher frequencies and it is necessary to understand and model the behavior of these components in a very accurate manner. This work focuses on utilizing Printed Circuit Board (PCB) test boards, or fixtures, made of FR4 for characterizing Surface Mount Device (SMD) components. Agilent's Advanced Design System (ADS) microwave circuit simulation software was used for designing the microstrip transmission lines as well as for generating the layout for manufacturing of the PCB. SMD resistors, capacitors …
