Feisilink Microelectronics launches the first RISC-V processor-managed Layer 2 SoC switch chip

On December 17, the first Dishui Lake China RISC-V Industry Forum was held in Lingang, Shanghai. At the meeting, Yang Qing, product line director of Feisling Microelectronics Technology Co., Ltd., introduced Xuanyuan 1030M, the first managed two-layer SoC switch chip with integrated RISC-V processor.

Wuhan Feisiling Microelectronics Technology Co., Ltd. is an integrated circuit design company jointly funded by FiberHome Communications and China Academy of Posts and Telecommunications Technology, a subsidiary of China Information and Communications Technology. It has a full-process chip solution from "demand to chip design, and then to system application". Feisiling is a leading IC design company in Central China, and a member of the China Semiconductor Industry Association (CSIA), the Design Branch (ICCAD), and the Communications Integrated Circuit Committee (CCIC) of the China Institute of Communications.

Yang Qing introduced that Xuanyuan 1030M is a managed SoC chip with integrated L2 Ethernet switching function, with a processing bandwidth of up to 30Gbps, designed for hub and switch deployment. It has an embedded RISC-V self-controllable CPU with a main frequency of up to 600MHz, which meets the needs of upper-layer protocol processing and device management; it has embedded 2 10G optical interfaces, 4 1G optical interfaces, and 8 1G electrical interfaces, supporting multiple communication protocols; it has complete L2 bridge, VLAN, ACL and Meter functions, supporting L2 multicast, STP, RSTP, mirroring and QinQ, etc.; it has an integrated 1.5Mbytes data cache, supports flow classification based on IEEE 802.1p QoS or DiffServ priority, and rate shaping based on ports and queues with a granularity of 8 Kbps; it has a rich scheduling strategy to ensure the stable operation of high-speed networks.

For different network architecture levels, for core switches, routers, edge gateways, network cards, PHY, etc., Feisiling has launched switching chips such as Xuanyuan 9, 9, 3 series, Fuxi, Nuwa, Shaohao series, etc.

In addition to switching chips, Feisling also has general-purpose and automotive-grade product lines for MCU products. Yang Qing introduced Feisling's automotive-grade MCU products under development. Based on the advantages of switching and security technologies, Feisling has jointly developed products in the three core areas of power safety, driving information, and body electronics with Dongfeng Motor. Among them, the high-performance Fuxi 2360 series chips for the power safety domain are equipped with a high-performance RISC-V Lockstep core, which has better performance than the ARM M7 core and a maximum clock frequency of 400MHz.

In addition, Yang Qing also introduced security chips, which are based on RISC-V+ hardware accelerators. The acceleration of key generation, signing, and signature verification are respectively 54.1 times, 42.8 times, and 17.5 times compared with software implementations, and are at the forefront of the world.
