Networks of language processors: a language theoretic framework for mainly locally connected processor arrays

We offer a new framework for describing mainly locally connected processor arrays, where the cell processors are defined by rewriting systems (grammars). The notion of the CNN template is defined by the local communication rules and the rewriting process following the communication. A striking similarity of the dynamics of the cellular network of language processors to the analog CNN dynamics can be demonstrated. As a future example, the dynamic activity pattern of the Internet could also be modelled in this way. In addition to the concepts and results pertinent to locally connected arrays, this contribution can be considered as a tutorial on networks of language processors as well. The introduction of coloring above the strings, the signals of the array, may lead to an analogic CNN system where strings and analog signals could be used in interaction.
