Hi3796CV300
8K+AI flagship SoC
Our flagship 8K+AI SoC, Hi3796CV300 supports 8Kp120 decoding and display and H.265, AVS3 and AV1 protocols for 8K ultra-HD TV and smart home applications. The octa-core 64-bit Arm Cortex-A73 CPU and Mali-G52 MC6 GPU and 4K UI combine to form an intelligent human-machine interface. The independent NPU is capable of powerful edge intelligent computing while the dual-core HiFi 3 high-performance audio DSP supports 3D audio decoding, audio effect processing, and intelligent audio processing. Gaming, intelligent interactions, and smart audiovisual applications are a reality thanks to flexible connection solutions.
