On March 26, during the RISC-V Eco-Technology Forum at the 2026 Zhongguancun Forum Annual Conference, the Chinese Academy of Sciences showcased the notable advancements made by Chinese research teams in the chip sector. These include the 'Xiangshan' open-source computing system and the 'Ruyi' native operating system, both of which are built upon the fifth-generation Reduced Instruction Set Computing (RISC-V) architecture. 'Xiangshan' stands out as the sole open-source high-performance processor system globally that utilizes this instruction set, challenging the dominance of high-end processor IP through its fully open-source design. Meanwhile, the 'Ruyi' system is tailored specifically for chips based on this architecture, effectively resolving compatibility challenges between chips and software. It circumvents the issue of 'fragmentation in the software ecosystem,' adheres to international high-performance standards, and guarantees the seamless and stable operation of both chips and software.
