IT Home reported on May 23 that Beijing Open Source Chip Research Institute (hereinafter referred to as "Kaixin Institute") announced today that on May 21, 2024, Kaixin Institute will hold an online conference, Officially released the world's first open source large-scale network on chip (NoC) IP - R&D code "Wenyuhe" to member units 。 This major breakthrough marks that Kaixin Institute has taken a solid step in promoting the development of server chip technology in the data center.
It is reported that NoC, as the core basic IP of server chips facing the data center in addition to the high-performance processor core, At present, there is only one ARM supplier in the world, and the use of RISC-V processor core is limited to a certain extent 。
Since the establishment of the project, the Open Core Institute has successfully completed the development and verification of NoC IP supporting 64 core interconnection after 18 months of intense development. At present, The NoC IP deliverable enterprise is evaluated , further promoting the development of RISC-V ecology.
Therefore, the Open Core Institute can provide the most important core basic IP for the CPU chip of the data center server, "Xiangshan" high-performance processor core and "Wenyuhe" large-scale on-chip Internet 。 This is also the first time in the world that the CPU chip of the data center server can be built based on the open source project.
▲ On the FPGA simulation platform, use "Wenyuhe" to realize the interconnection of 16 RISC-V cores, load Linux and run multiple programs, and use the Top command to check the CPU utilization
The press conference attracted about 100 engineers from more than 20 RISC-V chip enterprises across the country.
IT Home inquired and learned that, Beijing and Chinese Academy of Sciences In order to develop RISC-V ecology, a group of domestic leading enterprises and top scientific research institutions were organized to initiate the establishment of the core opening institute on December 6, 2021. Kaixin Institute is committed to accelerating the integration of RISC-V innovation chain and industrial chain, striving to initially build an open source chip technology system by 2025, and become the world's leading RISC-V industrial ecological center by 2030.
Bao Yungang, a researcher of the Institute of Computing Technology of the Chinese Academy of Sciences and the main person in charge of the "Xiangshan" RISC-V open-source processor, said:
The high-end processor chip contains two core IPs: one is the CPU core responsible for computing, such as the V1/N1/V2/N2 core of ARM Neoverse series; The other is the NoC (Network on Chip), which connects tens of hundreds of processor cores. It can be seen as a bridge within the chip, such as the ARM CMN-600/700 series IP.
The "Xiangshan" high-performance RISC-V processor core is the first class IP, which has developed to the third generation, and its performance can reach ARM N2. It was just released in Zhongguancun Forum some time ago. However, for the second type of NoC IP, especially the single chip hundred core NoC, currently only ARM CMN series are available in the world (there is no instance of the Arteris FlexNoC series), The price of a single authorization is up to hundreds of millions of yuan, and there are many restrictions 。
It is very difficult to design and implement a large-scale NoC (especially cache consistency), which has become a weak point of the global RISC-V ecosystem. This changed the situation. In 2022, Kaixin Institute launched the first generation NoC "Wenyuhe" project, which was led by teacher Wang Qi and was supported by many enterprises. After 18 months of research and development, we have successfully completed the development and verification of NoC IP that supports 64 core interconnection, and released it online on May 21. About 100 engineers from more than 20 RISC-V chip enterprises across the country participated, attracting widespread attention.
Now the research and development work of the second generation NoC has also started , will form closer adaptation and optimization with "Xiangshan" core, and better support the interconnection and expansion of AI accelerator. We look forward to more enterprise support and participation.

[Wenyu River] Located in the northeast of Beijing, it originates from the foot of Jundu Mountain, Changping District, Beijing, with a total length of 47.5 kilometers. Wenyu River is an important river that was developed earlier in the history of Beijing. As the shipping water source of the North Canal and the water transport channel in the north of Beijing, Wenyu River once played an important role in history. In history, Wenyu River was not only an important waterway for all dynasties, but also the water used by royal courts, gardens and lakes because of its clean and clear water quality.
Previously, a number of major scientific and technological achievements were collectively presented at the launch of major achievements at the opening ceremony of the 2024 Zhongguancun Forum Annual Meeting on April 25. The third generation "Xiangshan" RISC-V open-source high-performance processor core was unveiled, and its performance entered the first echelon in the world.
Bao Yungang also revealed that, Chinese researchers are still developing open source DDR controllers 。
