This work presents a new energy saving technique for modern digital designs. We propose Time Interleaved Multi-Rail (TIMR) - a method for providing two dynamic supply rails to a circuit. This technique uses the first supply rail to mask the transition delay while changing the voltage of the second rail....
As screen resolution and video decoding capability have increased, high-definition (HD) video in resolutions as high as 1920 x 1080 is rapidly becoming the standard. Ad-hoc streaming of HD video over 802.11 wireless networks, e.g., streaming from a mobile device to a television, is convenient for users, but is hampered...
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....
Information security is an important concern in today’s communication and business world. To achieve these security functions, cryptography is utilized. RSA and the Diffie Hellman key exchange are some examples of cryptography algorithms that use modular multiplication to compute modular exponentiations. Modular multiplication requires division operations which becomes very time...
Engineering students spend a significant amount of their undergraduate careers focused on technical theory and practice. This intensive student prepares them for their technical challenges in the future. This training is so intense that often the more 'soft skills' such as communication, leadership, design, and troubleshooting are left out or...
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...
Currently, there is no accurate, low-cost method to track divers. Watching bubbles can
give you an approximate xy-location, and expensive underwater radios utilizing ultrasonic waves can work if the diver knows where they are. Traditional radio waves do not work well in water due to the conductive nature of water....
Wireless High Definition Video Transmission (WHDVT) over 802.11-based networks enjoys widespread deployment among today's multimedia solutions. Examples include Intel® Wireless Display and Apple Airplay®, to name a few. In these systems, peer-to-peer networks are established over which H.264-encoded video is transported wirelessly to be decoded and played back at the...
With the need for higher spectral efficiency and data rates the rise of simultaneous transmit-and-receive (STAR) radios is becoming increasingly valuable. While many systems employ two separate channels for transmit and receive to double the data speed, this comes at the cost of doubling the RF band. This same performance...
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...
