L'informatica neuromorfa è un campo interdisciplinare che progetta sistemi hardware e software ispirati alla struttura e al funzionamento delle reti neurali biologiche, in particolare del cervello umano. Utilizza architetture non-von Neumann, in cui processori e memoria sono strettamente integrati, consentendo una computazione massicciamente parallela, un'elaborazione delle informazioni guidata dagli eventi e un funzionamento a basso consumo. Utilizzando elementi come neuroni spike e sinapsi artificiali, i sistemi neuromorfi imitano i meccanismi cerebrali di apprendimento, adattamento ed elaborazione sensoriale.

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[...]
