\"NPU<\/figure>\n\n\n\n

Artificial intelligence<\/a> has shifted rapidly from cloud-only execution to on-device and <\/strong>edge computing<\/strong><\/a>. A key technology enabling this shift is the NPU \u2014 Neural Processing Unit<\/strong>, a dedicated AI accelerator designed to efficiently run neural-network inference on smartphones, IoT devices, automotive platforms, and industrial systems.<\/p>\n\n\n\n

While CPUs and GPUs can process AI workloads, modern systems are increasingly architected with specialized neural engines<\/strong> to achieve better latency, energy efficiency, and privacy-preserving AI compute<\/strong>. This article explains what NPUs are, how they differ from CPUs\/GPUs\/TPUs, and where they fit in next-generation computing.<\/p>\n\n\n\n

1️⃣. What Is an NPU (Neural Processing Unit)?<\/h2>\n\n\n\n

Purpose-Built AI Compute Engine<\/h3>\n\n\n\n

An NPU (Neural Processing Unit)<\/strong> is a domain-specific processor optimized for neural-network computations \u2014 particularly matrix multiplication, convolution operations, and activation functions<\/strong>. NPUs accelerate inference workloads such as computer vision, audio processing, natural language tasks, and sensor fusion.<\/p>\n\n\n\n
