Alibaba’s chip design subsidiary launches RISC-V chip to boost performance of its cloud data centres
- The Zhenyue 510 chip provides support for applications such as artificial intelligence training, online transactions and big data analysis
- RISC-V has become the new hope for China in reducing dependence on foreign intellectual property providers amid the tech war with the US
Chinese tech giant Alibaba Group Holding’s chip design subsidiary launched a RISC-V-based controller chip for server storage at its annual Apsara cloud computing conference on Tuesday.
Zhenyue 510, a controller integrated circuit (IC) for enterprise solid-state drives (SSDs), will initially be deployed in Alibaba Cloud’s data centres, providing support for applications such as artificial intelligence (AI) training, online transactions and big data analysis, according to a statement from Alibaba Cloud. Alibaba owns the South China Morning Post.
The IC represents the first such chip developed by T-Head, Alibaba’s chip design unit, as Chinese cloud service providers adopt their own in-house chip designs to boost performance.
China’s RISC-V community appears unfazed by US threats to target chip standard
Alibaba Cloud said the chip provides a 30 per cent lower latency for input and output operations when compared with other ICs on the market.
An SSD controller is responsible for managing the underlying NAND flash memory in a server, and handling data input and output requests from the host.
The Zhenyue 510 is based on the RISC-V architecture, an open-standard instruction set architecture which gives chip developers the ability to configure and customise their designs. It has become the new hope for China in reducing dependence on foreign intellectual property (IP) providers amid an escalating tech war with the US.
American-based RISC-V IP companies, including SiFive, have been barred from selling their commercial IP cores to Chinese companies on the US export control blacklist.
US lawmakers, including Republican and Democratic Senators, are urging the Biden administration to take action on RISC-V on national security grounds, marking the first time that US politicians have looked at restricting the technology standard.

Before Zhenyue 510, T-Head had launched two proprietary silicon designs. The Hanguang 800 neural processing unit, its first AI chip, was released in 2019, and Yitian 710, an Arm-based central processing unit for cloud servers, was launched in 2021. Zhenyue 510 and the two previously announced chips are primarily used in-house, according to Alibaba Cloud.
In 2019, T-Head also debuted XuanTie 910, an Internet-of-Things processor that incorporates its RISC-V XuanTie series IP cores, which are licensed to other semiconductor design firms. Alibaba has made XuanTie IP cores open source on Github.
