D1 Chip Introduction
【The Light of Domestic Semiconductors】【Allwinner Technology & Ali Pinto Joint Development】
【RISC-V open source instruction set】【World's first chip with Pinto C906 core】
D1 is Allwinner Technology's first chip based on RISC-V instruction set, integrated with Ali Pinto's 64-bit C906 core, supports RVV, 1GHz main frequency, and can support Linux, RTOS and other systems. It also supports up to 4K H.265/H.264 decoding, a built-in HiFi4 DSP and up to 2GB DDR3 external connection, which can be applied to various fields such as smart city, smart car, smart business display, smart home appliance, smart office and research and education.
To facilitate developers' learning and partners' solution evaluation, Allwinner Online has customized a highly integrated dedicated development board based on the D1 chip, code name: Nezha!
