The implementation of neuromorphic computing on the hardware level can be realized by oxide-based memristors , [6] spintronic memories, [7] threshold switches, and transistors. A key aspect of neuromorphic engineering is understanding how the morphology of individual neurons, circuits, applications, and overall architectures creates desirable computations, affects how information is represented, influences robustness to damage, incorporates learning and development, adapts to local change plasticity , and facilitates evolutionary change.

Neuromorphic engineering is an interdisciplinary subject that takes inspiration from biology , physics , mathematics , computer science , and electronic engineering to design artificial neural systems, such as vision systems , head-eye systems, auditory processors, and autonomous robots, whose physical architecture and design principles are based on those of biological nervous systems. As early as , researchers at Georgia Tech published a field programmable neural array. In November , a group of MIT researchers created a computer chip that mimics the analog, ion-based communication in a synapse between two neurons using transistors and standard CMOS manufacturing techniques.

In June , spintronic researchers at Purdue presented a paper on the design of a neuromorphic chip using lateral spin valves and memristors. They argue that the architecture works similarly to neurons and can therefore be used to test methods of reproducing the brain's processing. In addition, these chips are significantly more energy-efficient than conventional ones.

Research at HP Labs on Mott memristors has shown that while they can be non- volatile , the volatile behavior exhibited at temperatures significantly below the phase transition temperature can be exploited to fabricate a neuristor , [14] a biologically-inspired device that mimics behavior found in neurons. Neurogrid , built by Brains in Silicon at Stanford University , [16] is an example of hardware designed using neuromorphic engineering principles.

The circuit board is composed of 16 custom-designed chips, referred to as NeuroCores. Each NeuroCore's analog circuitry is designed to emulate neural elements for neurons, maximizing energy efficiency.

The emulated neurons are connected using digital circuitry designed to maximize spiking throughput. A research project with implications for neuromorphic engineering is the Human Brain Project that is attempting to simulate a complete human brain in a supercomputer using biological data. It is made up of a group of researchers in neuroscience, medicine, and computing. The three primary goals of the project are to better understand how the pieces of the brain fit and work together, to understand how to objectively diagnose and treat brain diseases, and to use the understanding of the human brain to develop neuromorphic computers.

That the simulation of a complete human brain will require a supercomputer a thousand times more powerful than today's encourages the current focus on neuromorphic computers. The chip uses an asynchronous spiking neural network SNN to implement adaptive self-modifying event-driven fine-grained parallel computations used to implement learning and inference with high efficiency. Brainchip holdings will release an NSoC neuromophic system on chip processor called Akida in late While the interdisciplinary concept of neuromorphic engineering is relatively new, many of the same ethical considerations apply to neuromorphic systems as apply to human-like machines and artificial intelligence in general.

However, the fact that neuromorphic systems are designed to mimic a human brain gives rise to unique ethical questions surrounding their usage. Significant ethical limitations may be placed on neuromorphic engineering due to public perception. Neuromorphic engineering, by definition, is designed to replicate a human function: the function of the human brain. The democratic concerns surrounding neuromorphic engineering are likely to become even more profound in the future.

The European Commission found that EU citizens between the ages of 15 and 24 are more likely to think of robots as human-like as opposed to instrument-like than EU citizens over the age of The human-like nature of neuromorphic systems, therefore, could place them in the categories of robots many EU citizens would like to see banned in the future. As neuromorphic systems have become increasingly advanced, some scholars have advocated for granting personhood rights to these systems.

If the brain is what grants humans their personhood, to what extent does a neuromorphic system have to mimic the human brain to be granted personhood rights?

Critics of technology development in the Human Brain Project , which aims to advance brain-inspired computing, have argued that advancement in neuromorphic computing could lead to machine consciousness or personhood. However, skeptics of this position have argued that there is no way to apply the electronic personhood, the concept of personhood that would apply to neuromorphic technology, legally.

There is significant legal debate around property rights and artificial intelligence. In Acohs Pty Ltd v. Ucorp Pty Ltd , Justice Christopher Jessup of the Federal Court of Australia found that the source code for Material Safety Data Sheets could not be copyrighted as it was generated by a software interface rather than a human author.

Neuromemristive systems are a subclass of neuromorphic computing systems that focus on the use of memristors to implement neuroplasticity. While neuromorphic engineering focuses on mimicking biological behavior, neuromemristive systems focus on abstraction. There exist several neuron inspired threshold logic functions [6] implemented with memristors that have applications in high level pattern recognition applications. Some of the applications reported recently include speech recognition , [35] face recognition [36] and object recognition.

For ideal passive memristive circuits, it is possible to derive a system of differential equations for evolution of the internal memory of the circuit: [40]. This equation thus requires adding extra constraints on the memory values in order to be reliable. From Wikipedia, the free encyclopedia. Integrated circuit technology.

No notes for slide. Analog vlsi implementation of feed forward neural network for signal processing 1. Artificial intelligence is integral part of a neural network is based on mathematical equations and artificial neurons. The artificial neural network comprises of analog components like multipliers and adders along with the tan-sigmoid function generating circuit.

The given architecture uses components such as Gilbert cell mixer GCM , neuron activation function NAF to implement the functions an artificial neural network. With the balanced operation of the Gilbert cell clearer output is obtained by eliminating unwanted signals. Though computers are widespread in use, a human brain is considered to be far more superior to a digital computer. A simple example would be the way human brain processes a visual image or a fast reflex of human muscle when it comes in contact with an extreme heat source.

The human brain consists of neurons that send activation signals to each other thereby creating intelligent thoughts. The electronic version of a neural network algorithm called an artificial neural network also consists of neurons which send activation signals to one another. The goal of a neural network is to create an artificial intelligence which could replicate the functions of a human brain.

Thus neural is receiving much attention in past decade. A neural network is composed of highly interconnected processing units neurons which work together in parallel to achieve a specific task. Artificial Neural Networks are indeed self-learning mechanisms which don't require the traditional skills of a programmer. With the advent of new technologies there is a need to develop the processor to processes the information artificially as our biological system performs inside our body.

Test Pattern Generation of VLSI Circuits Using Hopfield Neural Networks

Artificial intelligence is realized based on mathematical equations and artificial neurons. An elaborate representation of the artificial neural network is as shown in figure1.

In this network, inputs v1, v2 are applied with the weight matrix, and then these weighted inputs of the adder are summed up. The output generated by adder blocks is given to the Neuron Activation function. The output of activation function is multiplied by weights again and given to the input blocks of output layer. Figure 1. This layered structure of neural network is implemented in VLSI using analog components. Gilbert cell multiplier and differential amplifier are used for different blocks.

Multiplication can be performed by various circuits.
