Abstract:

There are various modeling approaches of biomimetic hardware.

The first typical approach would be to model a biological system by using a nonlinear ordinary differential equation, which has a continuous time and continuous states (CTCS) and can be implemented by a nonlinear electronic circuit. The second typical approach would be to model a biological system by using a nonlinear difference equation, which has a discrete time and continuous states (DTCS) and can be implemented by a switched capacitor circuit. The third approach would be to model a biological system by using a numerical integration in a fixed-point or a floating-point number format or by a cellular automaton, which have discrete times and discrete states (DTDS) and can be implemented by a digital signal processor or a sequential logic.

On the other hand, in this talk, the fourth missing approach is discussed: to model a biological system by using an asynchronous cellular automaton, which has a continuous (state transition) time and discrete states (CTDS) and can be implemented by an asynchronous sequential logic. Also, advantages and recent applications of the fourth approach are introduced.

About CiNet's Friday Lunch Seminars:
The Friday Lunch Seminar is CiNet's main regular meeting series, held every week at 12.15 in the beautiful main lecture theatre on the ground floor at CiNet. The talks are typically 40mins long and orientated towards an inter-disciplinary audience. They are informal, social, and most people bring their own lunch to eat during the talk. They are open to anyone who is feeling curious and wants to come, regardless of where you work.
