The Session of Open-Source Chip Ecosystem Based on RISC-V(OCERV) was Successfully Held in Conjunction with the 2023 Zhongguancun Forum

Date: May 26, 2023
On the afternoon of 26th, May, the session of Open-source Chip Ecosystem based on RISC-V (OCERV) was successfully held in conjunction with the 2023 Zhongguancun Forum. This year event was administrated by the Chinese Academy of Sciences (CAS) and co-hosted by the Bureau of Major Research and Development Programs, CAS as well as the Institute of Computing Technology (ICT), CAS. Dr. YIN Hejun, Vice President of the Chinese Academy of Sciences (CAS) and Mr. YU Yingjie, Vice Mayor of Beijing were invited to deliver opening remarks and initiate release ceremony of achievements from the Strategic Priority Research Program of CAS.

In the achievement release ceremony of OCERV, Prof. Yungang Bao, Deputy Director of ICT, CAS, introduced XiangShan, the cutting-edge high-performace and open-source RISC-V processor. The 1st generation XiangShan with Yanqihu microarchitecture was successfully developed, taped-out and completed chip tests by ICT, CAS in 2021, which were fully sponsored by the Strategic Priority Research Program of CAS. As one of the most attractive open-source hardware development projects, XiangShan has been starred by 3,580 global individual developers and forked by 449 worldwide collaborators on GitHub, the world largest platform for repository hosting service.

As an essential engine of information technology, processor chips exhibit significant influence in building an informational, digital and intelligent human society. In recent years, RISC-V, a free and open instruction set architecture of processor chips, has attracted attentions in the globe for its original purpose — “Instruction sets want to be free”. In this year event, a number of domestic scholars and world-renowned experts in RISC-V-based open-source processor chips were invited to discuss fundamental techniques and efforts in ecosystem construction, share and present the latest achievements in research and development of RISC-V processor cores, arrange future directions, and inspire a worldwide approval to build a global community of open-source processor chips. About 200 attendees were attracted to OCERV this year.
