Abstract

In this paper, pattern formation occurring on the ACE16k CNN chip is presented. The CNN chip can be programmed with a cloning template in order to generate spiral waves and autowaves. The waves diffract from the internal sources which cannot be relocated on the network. However, by using initial and/or input images, sources (external sources) can be located at any place on the network. Furthermore a competition between autowaves generated by external and internal sources is observed. Propagation of autowaves on the inhomogeneous CNN array, formed by the fixed-state map, is presented.
