Cost Efficient and Low-Power Design for MCUs, Wearables, and AIoT Devices
VeriSilicon's Vivante DCNano series IPs are small-footprint, cost efficient, and low-power display controllers targeting wearable devices including smart watches and AR glasses, MCUs, AIoT, and IP cameras (IPC). Currently consisting of DCNano and DCNanoUltra, this series supports compressed and non-compressed inputs. DCNano series also provides diverse pre-processing and post processing features such as rotation and flip, swizzle, color space conversion, blending, and dithering.
