It combines a basic neuron with nine binary-programmable synapses and a programmable bias term. With these synaptic inputs the neuron is suitable for building a processing array like the

Such approach leads to a very compact implementation of the coefficient circuits and fast (digital) programming. In this programming scheme, the more complex templates are split into subtasks that are run successively. The structure allows a direct or algorithmic evaluation of the majority of templates proposed for B/W images. The transient mask is utilized in performing the local logic operations as well as in template operations. The proposed architecture is suitable for high-density implementations. A test structure of a 4 × 4 network has been implemented with a standard digital 0.18-m CMOS process. One cell occupies only 155 m 2 , making possible the implementations of very large networks on a single chip. The algorithms used for the logic function computations and selected template evaluations are described, and the corresponding measurement results are shown.

The scoping of technologies has been conducted by means of direct interactions with bioeconomy stakeholders and technology providers, analysis of the reports from bioeconomy-related projects, literature surveys, and internet searches. It is to highlight that technology mapping investigated here is focused on commercially available tools and services, which usually come with support, thus removing the necessity for expert knowledge or unusual technical proficiency. The list with over 100 items represents the current best knowledge of its creators and it is currently available through the ICT-BIOCHAIN project platform, serving as a database with technology descriptions and capability for updating the information. The ultimate objective of the database and the platform is to serve as a common point facilitating the cross-sectorial connection, where biomass stakeholders looking for new ICT, IoT, and Industry 4.0 solutions to make their work more efficient and sustainable can browse and filter out the records of their interest and obtain the contact information of the providers.

A device with an area of 5 mu m x5 mu m has been fabricated and tested. The structure has been simulated and analyzed using circuit equivalents with parameters obtained from measurements. The memristor is represented by a sinh (center dot)-type model. The performance of the memcapacitor is discussed, and some methods to improve it are proposed.

Binary programmable interconnections assure system versatility by providing the means of computing different logic operations. They also allow setting the redundancy level via the number of columns clustered to compute a certain function. A system operation is explained and visualized with a number of examples. The embedded scheme of fault tolerance can effectively mitigate permanent, as well as transient, faults. Some implementation and performance aspects are approached through simulations of single-electron tunneling structures. However, the proposed architectural concept is generic and can be applied to systems implemented with alternative nanotechnologies.

When using such a binary-programmable network, some templates need to be processed algorithmically, in other words, divided into subtasks that are processed consecutively. We classify templates into groups based on their properties and give guidelines as to how the division into subtasks (when applicable) is performed. A large collection of templates suitable for the proposed model is shown. We also describe one possible cell structure that realizes the binary-programmable model. The cell is modeled with Matlab and selected template simulations are shown.
