Ever wondered how your phone can recognize faces, understand voices, or enhance photos in a blink? Spoiler alert: It’s all thanks to super-smart tiny processors called Neural Processing Units, or NPUs. In this blog post, we’re diving into how these little wonders are making on-device AI faster and greener.

Challenges of On-device Generative AI Infrastructure

Let’s kick things off by talking about the hurdles on the road to smart devices. Generative AI, which powers cool stuff like voice assistants and image enhancements, guzzles a ton of computational juice. Here are the hiccups:

• Heavy Lifting: Generative AI needs lots of muscle to process data and learn patterns.
• Cloud Dependency: Traditional AI systems often rely on cloud-based CPUs and GPUs to function, but that’s not always great for on-device use because:
• CPUs: Limited in handling multiple tasks simultaneously.
• GPUs: Generate a lot of heat and consume plenty of power.
• Connectivity Issues: Always needing an internet connection to work.
• Lag and Risks: Facing delays, security vulnerabilities, and higher energy demands.
