Ecosystem Map
“Is there a single organization or website for RISC-V in China?” — there are alliances and communities, but for a long time there has been no single, filterable device-selection library. That is exactly the gap tryriscv.org is trying to fill.
Below are organizations, toolchains, RTOSes, development boards, and community entry points; for device data, head back to MCU Selection.
Who is driving RISC-V
RISC-V International
Switzerland / GlobalDefines the global RISC-V instruction set and extension standards, and owns the ISA specifications, certification, and ecosystem outreach.
https://riscv.org/China RISC-V Industry Consortium (CRVIC)
China · ShanghaiChina's RISC-V industry alliance, coordinating work across IP, chips, toolchains, and talent development.
http://www.risc-v.org.cn/China RISC-V Alliance (CRVA)
China · BeijingInitiated by the Institute of Computing Technology, Chinese Academy of Sciences; focuses on the open instruction-set ecosystem, the XiangShan processor, and open-source community work.
https://crva.ict.ac.cn/RISC-V International China Community
ChinaThe entry point for RISC-V International community events, technical working groups, and developer meetups in China.
