CARVER MEAD NEUROMORPHIC ELECTRONIC SYSTEMS PDF

Carver Andress Mead born 1 May is an American scientist and engineer. A pioneer of modern microelectronics , he has made contributions to the development and design of semiconductors , digital chips, and silicon compilers , technologies which form the foundations of modern very-large-scale integration chip design. In the s, he focused on electronic modelling of human neurology and biology, creating " neuromorphic electronic systems. Mead's contributions have arisen from the application of basic physics to the development of electronic devices, often in novel ways. During the s, he carried out systematic investigations into the energy behavior of electrons in insulators and semiconductors, developing a deep understanding of electron tunneling , barrier behavior and hot electron transport. Spitzer established the importance of interface states, laying the groundwork for band-gap engineering and the development of heterojunction devices.

Carver Mead

Biological in forma tion-processing systems operate on completely different principles from those with which most engineers are familiar. For many problems, particularly those in which the input data are ill-conditioned and the computation can be specified in a relative manner, biological solutions are many orders of magnitude more effective than those we have been able to implement using digital methods. This advantage can be attributed principally to the use of elementary physical phenomena as computational primitives, and to the representation of information by the relative values of analog signals, rather than by the absolute values of digital signals. This approach requires adaptive techniques to mitigate the effects of component differences. This kind of adaptation leads naturally to systems that learn about their environment.

Neuromorphic electronic systems

Conventional vision, auditory, and olfactory sensors generate large volumes of redundant data and as a result tend to consume excessive power. To address these shortcomings, neuromorphic sensors have been developed. These sensors mimic the neuro-biological architecture of sensory organs using aVLSI analog Very Large Scale Integration and generate asynchronous spiking output that represents sensing information in ways that are similar to neural signals. This allows for much lower power consumption due to an ability to extract useful sensory information from sparse captured data. The foundation for research in neuromorphic sensors was laid more than two decades ago, but recent developments in understanding of biological sensing and advanced electronics, have stimulated research on sophisticated neuromorphic sensors that provide numerous advantages over conventional sensors.

Computing Technology Overview

Neuromorphic engineering , also known as neuromorphic computing , [1] [2] [3] is a concept developed by Carver Mead , [4] in the late s, describing the use of very-large-scale integration VLSI systems containing electronic analog circuits to mimic neuro-biological architectures present in the nervous system. 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.
