La computación neuromórfica es un campo interdisciplinar que diseña sistemas de hardware y software inspirados en la estructura y el funcionamiento de las redes neuronales biológicas, en particular el cerebro humano. Emplea arquitecturas no von Neumann, en las que los procesadores y la memoria están estrechamente integrados, lo que permite la computación paralela masiva, el procesamiento de información basado en eventos y el funcionamiento de bajo consumo. Utilizando elementos como neuronas artificiales y sinapsis, los sistemas neuromórficos imitan los mecanismos cerebrales de aprendizaje, adaptación y procesamiento sensorial.

Neuron circuit
Patent published on the 2025-02-19 in EP under Ref EP4510043 by GUDE MICHAEL [DE] (Gude Michael [de])
Abstract: Convolutional neural networks (CNN) or spiking neural networks (SNN) are usually applied for implementation. Although CNNs can be realized purely digitally, they require a lot of energy due to the high processing power (MAC structures). SNNs can usually only be implemented with analog components and are therefore difficult to implement in circuits with a technology node below 10 nm.The present disclosure is aimed to realize electronic neurons that process pulse-width modulated signals. These neu[...]

Dynamics Research of the Hopfield Neural Network Based on Hyperbolic Tangent Memristor with Absolute Value
Published on 2025-02-17 by Huiyan Gao, Hongmei Xu @MDPI
Abstract: Neurons in the brain are interconnected through synapses. Local active memristors can both simulate the synaptic behavior of neurons and the action potentials of neurons. Currently, the hyperbolic tangent function-type memristors used for coupling neural networks do not belong to local active memristors. To take advantage of local active memristors and consider the multi-equilibrium point problem, a cosine function is introduced into the state equation, resulting in the design of an absolute val[...]
