A Recursive Growing & Featuring Mechanism for Nanocomputing Structures

The huge amounts of physical possibilities offered by the emerging nanotechnologies must be accompanied, beyond the uniform growing mechanisms supposed by the current serial and/or parallel extensions, by an appropriate structuring mechanism able to support efficiently the increasing functional demands. A recursive growing mechanism is proposed for the upcoming Nano-Era. The current growing mechanism involves only pure quantitative aspects. We consider as mandatory, for the very big sized systems, another mechanism which interleaves the quantitative aspects with the functional ones. Because the computational parallelism is implicit for the big sized systems, the growing mechanism must be supported also by an appropriate computational model. For the current systems we started from gates. For Nano-Era structuring mechanism we will start from cellular automata. The main difference is that for nanoarchitectures the growing mechanism and the featuring mechanism are unified in an unique recursive mechanism.
