Hardware Implementation of a High Speed Deblocking Filter for the H.264 Video Codec
(University of Waterloo, 2012-04-25)H.264/MPEG-4 part 10 or Advanced Video Coding (AVC) is a standard for video compression. MPEG-4 is currently one of the most widely used formats for recording, compression and distribution of high definition video. One ... -
Hardware Implementation of Barrett Reduction Exploiting Constant Multiplication
(University of Waterloo, 2019-10-01)The efficient realization of an Elliptic Curve Cryptosystem is contingent on the efficiency of scalar multiplication. These systems can be improved by optimizing the underlying finite field arithmetic operations which are ... -
Hardware Implementation of Fixed-Point Decoder for Low-Density Lattice Codes
(University of Waterloo, 2022-04-29)Low-density lattice codes (LDLCs) are a special class of lattice codes that can be decoded efficiently using iterative decoding and approach the capacity of the additive white Gaussian noise (AWGN) channel. The construction ... -
Hardware Implementation of Soft Computing Approaches for an Intelligent Wall-following Vehicle
(University of Waterloo, 2007-05-18)Soft computing techniques are generally well-suited for vehicular control systems that are usually modeled by highly nonlinear differential equations and working in unstructured environment. To demonstrate their applicability, ... -
Hardware Implementations of the Lightweight Welch-Gong Stream Cipher Family using Polynomial Bases
(University of Waterloo, 2019-01-28)In this thesis we develop a parametrized generic hardware implementation for the Welch-Gong (WG) stream cipher family for low power and low cost applications. WG stream ciphers operate over finite fields, and are comprised ... -
Hardware Implementations of the WG-16 Stream Cipher with Composite Field Arithmetic
(University of Waterloo, 2014-09-22)The WG stream cipher family consists of stream ciphers based on the Welch-Gong (WG) transformations that are used as a nonlinear filter applied to the output of a linear feedback shift register (LFSR). The aim of this ... -
Hardware-Aware Precoding and Digital Predistortion for Massive MIMO Transmitters
(University of Waterloo, 2022-05-19)To cope with the ever-increasing demand for higher data rates, reduced latency, and improved coverage, new technologies are needed to advance the current state of wireless communication systems. One of the promising new ... -
A Hardware-in-the-Loop Test Platform for Planetary Rovers
(University of Waterloo, 2011-08-02)Hardware-in-the-Loop (HIL) test platform for planetary rovers was designed, fabricated and tested in the present work. The ability for planetary rover designers and mission planners to estimate the rover’s performance ... -
A Hardware/Software Fuel Gauge Analog-to-Digital Converter Solution for Mobile Electronics Applications
(University of Waterloo, 2015-10-22)Power consumption is one of the key considerations in any mobile electronics design. As technology roadmaps advance in the mobile and wearable markets, there will be an evident push for lower power consumption in terms of ... -
Harmonizing the Scale: An End-to-End Self-Supervised Approach for Cross-Modal Data Retrieval in Histopathology Archives
(University of Waterloo, 2023-09-18)In recent years, the exponential growth of data across various domains has necessitated the development of advanced techniques to process and analyze multi-modal big data. This is particularly relevant in the medical domain ... -
A Hash-Chain Based Method for Full or Partial Authentication of Communication in a Real-Time Wireless Environment
(University of Waterloo, 2010-06-25)Real-time media streams are a common application on the Internet today. For many such streams, it is necessary to provide authentication, data integrity, and non-repudiation. Some applications where this type of security ... -
Header Parsing Logic in Network Switches Using Fine and Coarse-Grained Dynamic Reconfiguration Strategies
(University of Waterloo, 2014-04-29)Current ASIC only designs which interface with a general purpose processor are fairly restricted as far as their ability to be upgraded after fabrication. The primary intent of the research documented in this thesis is ... -
Healing Through Architecture
(University of Waterloo, 2015-08-26)Numerous studies show evidence of the body’s ability to “self-heal” when put into positive healing environments. This healing is enabled by the ability of the body to ‘tap into our internal pharmacies’ by activating the ... -
