Introduction

Nick lectures in digital and computer engineering. His research work has one focus - the design of faster processors. Whether general purpose microprocessors, or special-purpose devices for applications such as DSP and graphics, he is interested in any new techniques for increasing computation speed. His main work to date is the development of the European Logarithmic Microprocessor, details of which will be found at the link above.
