LG8111: Artificial Intelligence SoC Solutions for On-Device AI

A Highly-integrated AI Platform Enables Connectivity, Machine Learning, and Evolution

LG8111 AI Chip supports artificial intelligence functions such as visual/voice/control intelligence. LG8111 AI Chip is equipped with LG Neural Engine (LNE) which is an AI processor that mimics the neural network of the human brain to improve the processing of deep learning algorithms (low-power and low-latency). Products utilizing the LG8111 AI Chip can implement the ‘On-Device AI’ that learns and infers by itself.
