Neuromorphic Computing: A New Frontier in AI Hardware and Software

The rapid evolution of artificial intelligence (AI) requires innovations not just in algorithms but also in the underlying hardware and software architectures. Neuromorphic computing is at the forefront of this revolution, offering a paradigm shift in how AI-driven applications are designed and deployed. By mimicking the brain’s neural structures and functioning, neuromorphic chips promise to revolutionize both hardware efficiency and software design, enabling smarter and more energy-efficient AI systems.

What is Neuromorphic Computing?

Neuromorphic computing refers to designing computer systems that emulate the human brain's architecture and operation. These systems rely on neuromorphic chips, which use spiking neural networks (SNNs) to process information in a manner similar to biological neurons.
