[Allwinner V853-High-performance edge AI vision processing chip]

V853 is a new generation of high-performance, low-power processor SOC launched for the field of intelligent vision. It can be widely used in intelligent upgrade related industries such as intelligent door locks, intelligent attendance access control, network cameras, driving recorders, and intelligent desk lamps. .

V853 integrates Arm Cortex-A7 and RISC-V E907 dual CPU, built-in maximum 1T computing power NPU, uses Allwinner's self-developed Smart video engine, supports up to 5M@25fps H.265 encoding and 5M@25fps H.264 encoding and decoding, and at the same time Integrated high-performance ISP image processor to provide customers with professional-level image quality. V853 also supports 16-bit DDR3/DDR3L to meet the high bandwidth requirements of various products; supports 4lane MIPI-CSI/DVP/MIPI-DSI/RGB and other rich dedicated video input and output interfaces to meet the needs of various AI vision products; advanced The 22nm process has better power consumption and smaller chip area.

At the same time, Allwinner provides a stable and easy-to-use Linux SDK and hardware and software reference designs for the V853, which can help customers quickly achieve mass production.
