At this conference, Bao Yungang, a professor at the University of Chinese Academy of Sciences and a researcher at the Institute of Computing Technology of the Chinese Academy of Sciences, released a domestic open source high-performance RISC-V Processor core-Xiangshan. He said that there is currently no open source mainline like Linux in the CPU field, so the R&D team judges that the industry needs an open source high-performance RISC-V core that can be widely used in the industry and can support the academia to experiment with innovative ideas. The goal is to survive at least 30 years like Linux. With the support of the Institute of Computing Technology of the Chinese Academy of Sciences and Pengcheng Laboratory, Xiangshan has developed an open source high-performance RISC-V processor core through the China Open Instruction Ecology (RISC-V) Alliance and industry companies. The first mass-produced version “Yanqi” “Lake” plans to tape out in July this year, using TSMC’s 28nm process. Bao Yungang said that after more than a year of preparatory work, the project established a team and applied for funding. On June 11, 2020, Xiangshan established a code repository on GitHub. In one year, 25 classmates and teachers participated in the development of Xiangshan, and submitted 3296 codes, with a total of more than 50,000 lines and more than 400 documents. Xiangshan is an open source RISC-V processor core, its architecture code name is named after the lake. The first version of the architecture is codenamed “Yanqi Lake”. The RTL code for this processor was completed in April 2021, and it is scheduled to be taped out in July based on TSMC 28nm process. The current frequency is 1.3GHz. The second edition of the framework is codenamed “Nanhu”, which is a tribute to the 100th anniversary of the founding of the party. “Nanhu” plans to tape out by the end of this year, and will use SMIC’s 14nm process with a target frequency of 2GHz. Specifically, the “Yanqi Lake” architecture is an out-of-order processor core with 11 stages of pipeline, 6 launches, and 4 memory access components. The launch width is already comparable to some ARM high-end processor cores, but it has not been fully optimized, so there is still a big gap in actual performance. Professor Yungang Bao’s team hopes that through continuous iterative optimization (“Nanhu”–> “X Lake”–> “Y Lake”–> …) in the future, the performance will reach the level of ARM A76. In 2020, the team completed a test tape out of an 8-core tagged RISC-V processor based on Chisel, using TSMC’s 28nm process. The R&D staff built a set of process-oriented automatic regression test framework based on GitHub CI. Starting from September 2020, this test chip has successfully started the Linux/Debian system on the FPGA. One of the important decisions for the development of the “Xiangshan” processor core was to choose the agile design language Chisel, because the development efficiency is much higher than that of Verilog, and the same function is realized. The amount of Chisel code is only 1/5 of Verilog. Another important decision in the development process of “Xiangshan” is to attach great importance to building processes and tools that support agile design. This provides a scientific process for chip development and ensures the success rate. In addition, the R&D team has developed more than a dozen unique tools to support this agile design process. IT Home understands that Xiangshan is currently developing the next-generation architecture “South Lake”. The goal is to tape out by the end of this year. Based on SMIC’s 14nm process, the frequency will reach 2GHz, and the SPECCPU score will reach 10 cents/GHz, supporting dual channels DDR memory and more functions such as PCIe, USB, HDMI, etc. According to the official, the research and development of the Xiangshan processor core is supported by Beijing Zhiyuan Artificial Intelligence Research Institute and senior experts from Beijing Microcore. In the second phase, it will also be jointly developed with partners such as ByteDance, ESWIN, and Unisilicon Technology.

Faced with an attractive market, there is no reason to give up.
The Great Wall, which once claimed that it would no longer build cars without being the first in the field of SUVs, still broke its promise after all.

In 2014, Great Wall Motor said it “temporarily abandoned” its car business. At that time, competition in the car market was extremely fierce. Faced with the continuous downward pressure of joint ventures, the market dividends that independent brands could receive were limited. In order to focus resources on advantageous sectors, Great Wall Motor resolutely chose to temporarily abandon its car business. A few days ago, Li Ruifeng, vice president of Great Wall Motors and general manager of the WEY brand, revealed that Great Wall Motors has restarted the sedan project. The first sedan will be placed under the WEY brand and is scheduled to be released in May this year. First of all, regardless of whether Great Wall Motor’s decision to plunge into the embrace of SUVs was right or wrong, Great Wall Motors now only relies on SUV products. Although not the first, it has indeed been firmly among the top three domestic car companies. This coincides with the critical period when the tank brand is separated from the Wey brand. WEY needs more business support and only relies on high-end urban SUVs. The product line is still slightly monotonous. Diversification will be the way out for the WEY brand to grow. And choosing to enter the car field this year, Great Wall Motors is obviously well prepared. In 2020, the Great Wall lemon, tank, and coffee platforms will be officially released. With the support of intelligent and modular platforms, it will be able to quickly launch a variety of new models to achieve product empowerment, technology empowerment, and rapid coverage of more categories. This is undoubtedly the confidence that Great Wall Motor chose to enter the car market at this time. No company is willing to give up the car production line that is close to hand after working hard to develop a modular architecture, not to mention that the market has been suffering from the absence of cars in the Great Wall for a long time. According to the investment project of Great Wall Taizhou Branch, Great Wall will establish complete vehicle manufacturing and chassis manufacturing projects in Taizhou’s factory. The main models put into production are two sedans, a compact car and a medium-sized car. All models are new energy vehicles and will be driven by pure electric power. In addition, in addition to the gradual maturity of core technologies, Great Wall Motor’s factory layout and dealer layout have matured, and the road for the production of cars has been paved. Let’s look at the domestic car market. Let alone joint venture cars, among the independent brands, Geely Emgrand and Changan Yidong have performed well in the domestic car market. Geely Auto’s Emgrand sales have surpassed 3 million in 2020, with an average monthly sales of more than 10,000; Changan Auto’s sales have remained high since the launch of the Yidong PLUS model, and Changan Yidong surpassed Emgrand in February and March. First place for autonomous cars. Great Wall Motors has entered the sedan project at this time, and has made B-class cars a key model. The opportunity for WEY is obviously great. (Fictional picture of netizens) Only relying on SUV models can be the leading auto company of independent brands. Now that the sedan project is restarted, sales growth is one aspect. Once “abandoning” has achieved Great Wall Motor’s SUV dominance, but now it is regaining the “old dream” of cars, which is even more exciting. What do you think of the upcoming B-class sedan of the WEY brand? Welcome to leave a message below and discuss with us!
