CNN: Twenty years later

This speech will present the state-of-the-art of the CNN (Cellular Neural Network) universal chip and its future applications. The speech will last two hours without coffee break. After the speech, a 20 minutes interactive talk among the speaker and audience will be held on the great event: Experiment Verification of Memristor by HP researchers has been done last month. As is well known that the Memristor is predicted by Prof. Chua 37 years ago as the fourth basic circuit element besides the other three elements: resistor, capacitor and inductor.Thus this event is recognized as the basic natural science discovery besides those made by Ohm, Maxwell and Faraday in the 19
^th
century.
