image-20210508170105959

D1 is Allwinner's first SoC based on the RISC-V ISA. It integrates the 64-bit C906 core of Ali T-Head, supports RVV, 1GHz frequency, and supports Linux, RTOS and other systems. At the same time, it supports up to 4K H.265/H.264 decoding, a built-in HiFi4 DSP, and an external connection of up to 2GB DDR3, which can be used in many fields like smart cars, HMI, Smart home, education, etc.

In order to facilitate the learning of developers , AWOL has customized a high-integration dedicated development board based on the D1 chip, code name: Nezha!
