Alibaba introduces a range of RISC-V processors with the Xuantie family ranging from the E902 micro-controller class core to the C910 core for servers in data centers. This also includes the XuanTie C906 core found in the Allwinner D1 single-core RISC-V processor.
While RISC-V is an open standard and there’s a fair share of open source RISC-V cores available, many commercial RISC-V cores are closed source, but Zhang Jianfeng, President of Alibaba Cloud Intelligence speaking at the 2021 Apsara Conference, announced that T-Head had open-sourced four RISC-V-based Xuantie series processor cores, namely Xuantie E902, E906, C906, and C910, as well as related software and tools.
The RTL for the four cores released on T-Head Semiconductor’s Github account under Apache 2.0 license. Each repository has its own instruction and code. Alibaba also highlighted software support for their RISC-V cores with AliOS, RT-Thread, FreeRTOS, Linux, and Android, and claims to have shipped over 2.5 billion XuanTie cores so far.
