What is Neuromorphic Computing?
Neuromorphic computing is a technology that mimics the brain’s neurons and synapses. It differs from the traditional von Neumann architecture, where data and processing are handled by separate memory and processor units. Neuromorphic chips, such as Intel’s Loihi 2, integrate data storage and processing, eliminating the von Neumann bottleneck. This technology employs spiking neural networks (SNNs), which activate only when necessary data is processed, resulting in significantly lower energy consumption.
In 2023, the Indian Institute of Science (IISc) developed a molecular film-based neuromorphic system capable of storing and processing data in 16,500 states. This technology enables training large language models (LLMs) on small devices like smartphones, making it globally unique,Neuromorphic Computing: Brain-Inspired Technology Transforming the Future
