Towards noise-driven computing architectures for coarse-grained devices and materials

Research Aim

The object of this research group is the development of a new information processing architectural design that possesses ‘coarse-grained devices’ as calculation elements. ‘Coarse-grained device’ here refers to a device with characteristic variations and fluctuations (ambiguity).

Role and Need in the Group

The role of this group is to combine the characteristics (fluctuation and non-linearity) of the molecular devices that the A01-03 groups have developed and elucidate the elements that can be included in coarse-grain elements, system architectonics, and their combinations. Tight cooperation within these research areas is indispensable for the creation of an ‘exit-oriented hierarchical information processing systems design’ that could not have been accomplished in a single area.

Research Content

We will establish a circuit and systems design for coarse-grained elements. In order to expand the use of coarse-grained elements to new nano-integrated information processing system applications, we will engage in research in the following areas: implementation of logical operation circuits and early brain-like information processing circuits using coarse-grained elements; elucidation of the physics of stochastic resonance gates that are the foundation of circuit applications using coarse-grained elements; and the probability of the design methods of brain-like asynchronous logic circuits that combine stochastic resonance gates.
