RIOS Retreat 2023


Since its establishment, the RISC-V International Open Source (RIOS) Laboratory has garnered widespread attention and support from various sectors of society. In order to further promote and enhance the development of the global RISC-V open-source technology ecosystem, RIOS, in collaboration with the CityU Architecture Lab for Arithmetic and Security (CALAS) of City University of Hong Kong, co-hosted the “RIOS & CALAS HK RISC-V Day 2023” on October 27-28, 2023.

The visit to Hong Kong aimed to deepen understanding of the academic and innovation ecosystem in Hong Kong, strengthen exchanges and cooperation between academia in Hong Kong and mainland China, promote academic research and knowledge sharing, and facilitate collaboration among domestic and international chip and computer industry leaders. Together, they explored the current development status and future opportunities of RISC-V in the Guangdong-Hong Kong-Macao Greater Bay Area.

On one hand, the laboratory showcased recent research achievements to industry experts and scholars; on the other hand, the laboratory invited frontline experts from internationally renowned universities and supercomputing centers to deliver exciting cutting-edge academic presentations on the new computing architecture revolution driven by RISC-V and core technologies of open-source chips. This initiative aimed to provide students with a more comprehensive understanding of the international academic environment, enhance their cross-cultural communication skills and professional capabilities, and lay a solid foundation for their future development on international platforms.

The Highlights of the Event

Cutting-edge Technology Presentations: The RIOS Laboratory showcased its advancements in chip design, large language models, AI chip engineering, low-level computer compilation, vector extension instruction set testing and verification, and Open EDA/PDK to renowned experts and scholars from around the world.

Student Achievements: Notable achievements by students were highlighted, including winning first place in international semiconductor design competitions and receiving awards for designing the world’s first AI-designed RISC-V CPU in the “AI-generated Open Source Chip Challenge.”

Special Presentations by Experts: World-class experts in relevant fields delivered specialized presentations, sharing insights into research trends and the latest developments in international advanced semiconductor initiatives, including open-source chip design and high-efficiency supercomputing architectures based on RISC-V and AI.

Personalized Guidance: Senior experts provided face-to-face, one-on-one guidance to students on their research topics and future development, fostering open and engaging discussions and providing invaluable mentorship.

Opportunities for Students: The event provided students with a rare opportunity to gain insights into the latest industry technologies, understand the newest innovations and technological trends in the industry, and maintain their research capabilities at the forefront of relevant disciplines.

The RIOS Laboratory organized a trip for students to visit the Hong Kong Science Park, where they had the opportunity to tour multiple international research laboratories. This experience allowed them to gain firsthand knowledge of the forefront of innovation and technological development in the Guangdong-Hong Kong-Macao Greater Bay Area, as well as insights into the ecosystem and industrial prospects. The students found the experience to be highly enriching and gained valuable insights into the region’s innovation and technology landscape.

    RISC 40TH Anniversary Exhibition

    Ecosystem Wants To Be Free

    Recently, the “RISC 40th Anniversary Exhibition” was officially opened in Shenzhen Industrial Exhibition Hall. It was jointly held by the Municipal Industrial Exhibition Hall, the RISC-V International Open-Source Laboratory of Qinghua-Berkeley, Silicon Valley Computer History Museum and other units. Zheng Hongbo, member of the Standing Committee of Shenzhen Municipal Committee and the Party Leading Group of Shenzhen Municipal Government; Zhang Lin, Vice Minister of the Organization Department of Shenzhen Municipal Committee; Yu Xiquan, Secretary of the Party Leading Group and Director of the Municipal Bureau of Industry and Information Technology; Zheng Xuan, first-level researcher; Li Huilai, Deputy director of the Municipal Science and Technology Innovation Committee; Li Zexiang, Professor of the Department of Electronic and Computer Engineering of Hong Kong University of Science and Technology and founder of Shenzhen Institute of Science and Technology; Gao Hong, Vice Provost of Tsinghua University, Executive Dean of Tsinghua University Shenzhen International Graduate School and other guests attended the opening ceremony.

    Yu Xiquan, secretary of the Party Group and director of the Municipal Bureau of Industry and Information Technology, said in his speech that RISC 40th anniversary exhibition showed the open-source concept of RISC in an all-round way by reviewing the development course of RISC for 40 years, and embodied the spirit of seeking truth, being innovative and pursuing excellence of the industry. With the global popularity of RISC-V, this open source and streamlined instruction set will bring more opportunities for source innovation, technological innovation, achievement transformation and enterprise cultivation to the chip field, and infuse new vitality into the chip industry.

    David Patterson, Director of RIOS Laboratory, delivered a speech online. David Patterson said that although the chip and computer industry has been deeply internationalized, there is still pressure for global cooperation. He hoped that open source could bring the world together and find areas of cooperation, so as to help everyone in the world.

    Gao Hong, vice provost of Tsinghua University and executive dean of Tsinghua University Shenzhen International Graduate School, mentioned at the opening ceremony that for enterprises, RISC-V open-source system can reduce the threshold of architecture authorization and save the cost of chip research and development. It is a new choice to solve key problems in the field of computer chip design, and also a new breakthrough with bright prospects. It is hoped that the public can come to the scene to see the development process and application status of RISC reduced instruction set computer, to further enhance the attention and awareness of the chip industry, and hope that this activity can inspire more aspiring young people to devote themselves to RISC technology and chip industry.

    After the open ceremony, the guests visited the “RISC 40th Anniversary Exhibition”. The exhibition reviews the origin, foundation, core, invention, and creation of the development of the global electronics computer industry and echoes the innovation and application of the development of electronics and computer industry in China, integrating the four decades of innovation and entrepreneurship stories from coast to coast. This exhibition aims to build a platform for chip technology exchange and exhibition, stimulate innovation, deepen cooperation, form the driving force for the development of RISC-V open-source chip, promote the development of the entire chip industry with the source innovation of chip design, promote the linking innovation of the whole chain, and build an open and win-win open-source chip design ecosystem.

    At the same time, the Industrial Culture research class of Shenzhen Industrial Exhibition Hall was opened, which will be held every weekend for two months, showing students the development history of RISC and Shenzhen’s industrial construction achievements in the semiconductor field. It is hoped that through normal research activities, teenagers’ interest in chip industry and even manufacturing industry can be cultivated, and the seeds of intelligent manufacturing in China can be planted in the growth of young people.

    The show is open and inclusive.

    A tiny nanoscale chip can reveal its intricate internal structure to everyone.

    Just like RISC-V’s open-source ecosystem provides a more innovative and free sense of use to all users.
