China’s top chip designers form RISC-V patent alliance to promote semiconductor self-sufficiency

At a RISC-V industry forum held in Shanghai’s Lingang New Area on Monday, nine chip companies – including Alibaba Group Holding’s chip unit T-Head and Shanghai-listed VeriSilicon Holdings – agreed to form the alliance that includes a condition for members to not sue each other over patent infringement, according to local media The Paper, under the state-run Shanghai United Media Group. Members of the alliance will share patents with each other and license them to third parties in the name of the alliance, according to Dai Weimin, chairman of VeriSilicon and head of the China RISC-V Industry Alliance, formed in 2018. The new alliance aims to contribute to a “healthy” open-source chip ecosystem and promote the rapid development of RISC-V technologies. China bets on open-source RISC-V for chip design to avoid ‘being cut off’ The alliance, which also includes RISC-V intellectual property (IP) vendor Nuclei System Technology and Baidu-backed chip maker StarFive, marks the latest move to support the development of an open source alternative to standards controlled by foreign tech giants. RISC-V is an open-standard instruction set architecture that gives chip developers the ability to configure and customise their designs. First published in 2010, it is the fifth generation of cooperative projects from researchers at the University of California, Berkeley. It has gained popularity in China amid hopes that the technology can help it break what is largely a duopoly controlled by US-based Intel and UK-based Arm, bringing the country closer to its strategic goal of technological self-sufficiency. Intel’s x86 is the dominant chip design architecture for personal computers and servers. Arm develops the architecture behind most mobile chips, predominantly found in smartphones and tablets. The British firm is currently owned by Japan’s SoftBank, but it is set to go public in what may be the largest initial public offering of 2023. China’s enthusiasm for RISC-V stems from its numerous benefits as an open standard. As the cost of innovation in chip design is high, a chip start-up has to raise around US$20 million to deliver a working prototype, compared with US$3 million for an internet start-up, according to the RISC-V Foundation, which manages the standard. As an open source chip ecosystem, RISC-V can offer faster time to market with lower costs, lowering barriers to entry for the industry, the foundation said in an article published earlier this month. Shanghai – China’s hub for semiconductors, which along with artificial intelligence and biomedicine is one of the city’s three leading industries – became the first place in the country to kick-start RISC-V development. In 2018, the city introduced specific financial incentives to encourage companies to develop RISC-V processors and related IP as part of the city’s larger incentive package for the chip industry. Since the city founded the RISC-V Industry Alliance with local start-ups that same year, its membership has grown to 173 companies. Chinese scientist says semiconductor talent can help weather decoupling. Chinese scientist Bao Yungang recently said in a post online that China could weather sanctions better than Russia because of its semiconductor talent and the ability to fork the open source RISC-V architecture. Dai from VeriSilicon said the alliance has learned from a dispute in the early 2000s between Microsoft and the Linux Foundation, the consortium that maintains the Linux operating system, which will help it address challenges from chip giants. In 2018, Microsoft joined the Open Invention Network, giving the Linux community royalty-free access to the software giant’s 60,000 patents and ending the years-long patent war with the Linux Foundation.
