Specialized Video Processing NPU IP

Overview

The WAVE-N is a custom NPU designed to work for imaging application at high-quality and high-resolution in edge devices. Compared to typical generic NPU, it provides extreme computation power in 16bit floating point format for high performance together with competitive enough area and power efficiency.

Target Performance

C&M’s imaging solutions powered by WAVE-N, as of 2Q 2025 C&M currently offers three types of neural networks:

  • SR | Scale X2 : 1920x1080 → 3840x2160 60fps @500MHz
  • NR |  RGB / Bayer : 1920x1080 60fps @500MHz
  • NR+Demosaic | 8M(4096x2048) sensor 30fps @500MHz
