Allwinner V837S

Overview

Allwinner V837S is a new generation of high-performance H.264/H.265 encoding SoC targeted for the field of IP Camera. It integrates single-core Cortex-A7@900MHz and single-core RISC-V@600MHz, and also supports deep learning for built-in dedicated human detection module. Allwinner V837S is also designed with a new generation of high-pertormance ISP image processor and video encoder with professional encoding quality, low encoding bit rate and mainstream-level image processing capability. In addition, Allwinner V837S supports 64MB DDR2 and rich peripheral interfaces, such as USB, SDIO, and Ethernet, to meet the requirements of various IP Camera products.
