    Research Projects

    Dr. Bolton's research experience has been in the areas of multiple-valued logic circuits, computer-aided design systems, and pattern recognition. In particular he has carried out work on Application Specific Integrated Circuits (ASICs) in the areas of ECG processing, Viterbi decoding, and Canonical-Signed Digit code filters. He has developed software for use with standard cell libraries for integrated circuit design software. He is particularly interested in the area of minimization and synthesis of multiple-valued logic functions.

    His research on multiple-valued logic has lead to the specification of a new, functionally-compete set of operators for use in multiple-valued logic. Using this set of operators it is possible to more efficiently (based on the number of product terms) realize circuit functionality. This research was done in cooperation with A.K. Jain and M.H. Abd-El-Barr.

    His development of a Canadian Microelectronics Corporation (CMC) Analog Artist version of the Gennum linear bipolar array GA911 technology allows the CMC to offer an undergraduate design technology to Canadian university members at no cost. This initiative is supported by facilities available to the CMC through Gennum and Tundra Semiconductor.

    His research in pattern recognition has lead to an ECG analysis systems capable of identifying harmful ECG morphologies and arrhythmia. This system is based upon Hilbert Transform processing of the ECG data and subsequent recognition using custom ICs and/or software based systems. The process is particularly suitable to real-time processing of Holter type ECGs since it can lead to long term monitoring.

    Current research projects include work in the use of current-mode CMOS logic multiple-valued logic in the area of neural networks. This includes the use of VHDL (using a mixed-signal current-mode CMOS logic multiple-valued library developed with H-Y. Teng and A.K. Jain) to specify the structure of the networks and to use synthesis to construct them. Another research project is the multi-disciplinary NITEOWL (Nightsky Imaging and Tomography Experiment on Ozone using Light from Stars) project. This project combines expertise from the departments of Engineering Physics, Electrical Engineering, Mechanical Engineering, Mathematics and Statistics, and Commerce. The project has reached the final proposal stage with the results of the Canadian Space Agency Small Payloads Program Application Opportunity known in early 1997. Related to this project will be the development of an Attitude Video Camera pattern recognition software system and the development of a mission simulator.
