Office

Professor Morley joined the Department of Electrical Engineering in 1981 after founding Micro-Term, Inc. and serving as its vice-president of engineering for five years. While at Micro-Term he designed the first microprocessor-based computer terminal and communication devices for the hearing impaired.

Since joining the department he has actively pursued research in low power VLSI signal processing circuits for developing a digital hearing aid. Work to date has fabricated a three-chip system that provides noise reduction, feedback equalization and custom fitting.

Professor Morley is currently conducting research to develop and commercialize a magnetic fingerprinting technique, useful for authenticating all types of magnetic media. Use of this technique is expected to dramatically reduce credit card fraud world-wide. A custom integrated circuit is currently under development at the University. This research is funded by the Mag-Tek Corporation.

In the area of computer architectures, Professor Morley and his students designed and built a massively parallel computer system featuring 2304 SIMD GAPP processing elements.

Other completed research projects that Professor Morley has supervised include: devising methods for achieving fault tolerance in neural networks; fabricating a VLSI-based power meter for appliances; designing and constructing a multi-processor DSP system; developing a VLSI voice activated switch for NASA; and developing a VLSI coprocessor chip for the GAPP SIMD processing element.
