NPU It is mainly used for mobile phone terminal side AI Reasoning engine for computing acceleration , comparison GPU More professional . Use NPU, It can make the mobile phone calculate more data per unit time , Unit power consumption AI It's also more powerful , Relatively traditional CPU and GPU Achieve an order of magnitude improvement , Achieve better energy efficiency .
