These steps forward and the ability of our unique design-oriented deterministic methodology to yield more extensive multitile systems suggest that proposed general-purpose nanocomputers can be realized in the near future.

The programmable multitile circuit was also reprogrammed to a functionally distinct 2-bit full adder with 32-set matched and complete logic output.
#Finite state automata toy grammar registration#
Our system realizes the complete 2-bit logic flow and clocked control over state registration that are required for a finite-state machine or computer. The nanoelectronic finite-state machine integrates 180 programmable nanowire transistor nodes in three tiles or six total crossbar arrays, and incorporates both sequential and arithmetic logic, with extensive intertile and intratile communication that exhibits rigorous input/output matching. Each tile/module consists of two interconnected crossbar nanowire arrays, with each cross-point consisting of a programmable nanowire transistor node. This methodology allowed construction of the nanoelectronic finite-state machine through modular design using a multitile architecture. The system was fabricated using a design-oriented approach enabled by a deterministic, bottom–up assembly process that does not require individual nanowire registration. We describe how such a strategy has led to the design, construction, and demonstration of a nanoelectronic finite-state machine. It requires a design and fabrication strategy that can address individual nanometer-scale electronic devices, while enabling large-scale assembly of those devices into highly organized, integrated computational circuits. Implementation of complex computer circuits assembled from the bottom up and integrated on the nanometer scale has long been a goal of electronics research.
