What are neural processing units (NPUs) and why are they so important to modern computing?

  • Neural Processing Units (NPUs) are circuitries designed to mimic the human brain's parallel architecture, unlike traditional CPUs.
  • NPUs have a history dating back to the mid-1940s, with Warren McCulloch and Walter Pitts' neural network being early examples.
  • The resurgence of neural networks occurred in 1986, gaining traction with the success of speech recognition in the early 2000s.
  • NPUs, inspired by the brain, utilize deep learning instruction sets to execute computations with great speed and low power consumption.
  • Applications of NPUs include edge detection in photos, AI-powered features in smartphones, and enhancing video calls.
  • NPUs have gradually become integrated into various devices such as smartphones, laptops, and even Windows PCs for AI-enhanced functionalities.
  • NPUs are expected to advance rapidly, potentially doubling their processing power every year or two, leading to more sophisticated AI applications.
  • Future implications of NPUs include the development of personal AI agents and their integration into a wide range of devices, transforming user experiences.
  • NPUs have the potential to revolutionize various industries, from personalized news services to AI-powered humanoid robots that understand human behavior.
