According to Milk-V's official introduction, Ruyi Xiangshan laptop was developed by the Institute of Software, Chinese Academy of Sciences, with the participation of Qunxin Shining Technology, Yingqi Intelligent, and Beijing Kaixin Institute. It is the world's first notebook equipped with Xiangshan Nanhu processor.

The Ruyi Xiangshan laptop is equipped with a Xiangshan Nanhu processor with a maximum speed of 2.5GHz and 8GB DDR5 memory;

In terms of display, it uses a 14-inch high-definition LCD screen, and the notebook is integrated with an AMD RX 550 independent graphics card, which supports dual-screen display;

In terms of interfaces, it provides 2 USB 3 interfaces, 2 2.5Gbps Ethernet ports, and is also equipped with a touchpad that supports 9 gesture operations.

The internal structure of the Ruyi Xiangshan notebook was also demonstrated on site, and the Xiangshan Nanhu laptop security challenge was announced. The Ruyi Xiangshan Nanhu notebook was used as a physical test object to try to discover possible security vulnerabilities of the Xiangshan IP, with an initial prize pool of 50,000 RMB.

IT Home Note: Xiangshan uses lakes to name each generation of architecture - the first generation architecture is Yanqi Lake, the second generation architecture is Nanhu Lake, and the third generation architecture is Kunming Lake.

The second-generation "Xiangshan" processor (Nanhu architecture) supports the RV64GCBK instruction set. The V1 version is for dual-core scenarios. The RTL code freeze was completed in February 2023, the GDSII freeze was completed in June 2023, and it was put into production in November 2023. The frequency reached 2GHz at the 14nm process node. The Nanhu V2 version includes improved designs such as MBIST. The RTL code freeze was completed in February 2023, and it was put into production in April 2023. It was returned in October 2023 and successfully lit up and started Linux.

On August 24, 2022, the Institute of Computing Technology of the Chinese Academy of Sciences, Beijing Open Source Chip Research Institute, Tencent, Alibaba, ZTE, ThunderSoft, Eswi, and Suanneng formed a joint R&D team to carry out the joint development of the third-generation Xiangshan (Kunming Lake architecture).

At the opening ceremony of the 2024 Zhongguancun Forum Annual Conference in April this year, the third-generation "Xiangshan" RISC-V open source high-performance processor core was unveiled, and its performance entered the first echelon in the world.
