Vhdl Design And Simulation For Embedded Zerotree Wavelet Quantisation, Hung Huynh
Theses : Honours
This thesis discusses a highly effective still image compression algorithm – The Embedded Zerotree Wavelets coding technique, as it is called. This technique is simple but achieves a remarkable result. The image is wavelet-transformed, symbolically coded and successive quantised, therefore the compression and transmission/storage saving can be achieved by utilising the structure of zerotree. The algorithm was first proposed by Jerome M. Shapiro in 1993, however to minimise the memory usage and speeding up the EZW processor, a Depth First Search method is used to transverse across the image rather than Breadth First Search method as initially discussed in Shapiro's …

Networking 8-Bit Embedded Controllers, Using The Controller Area Network Method, Brett Wilkinson
Theses : Honours
The initial aim of this project was to create an ethernet (IEEE 802.3) Communications System. The system was to connect Embedded controllers to facilitate the operation of a real time operation. After extensive investigation and scheduled meetings with industry, it became apparent that a superior communication system for this type of task lay in the Controller Area Network (CAN) standard. Communications Networks are extremely susceptible to volatile surroundings. A vital controller network necessitates that its communication network be invulnerable to high noise levels. It is also imperative that critical messages from one controller reach their destination on time. CAN was …
