Milk-V Vega, the world's first RISC-V-based 10GbE switch, is introduced
Shenzhen MilkV Technology (Milk-V) has announced the world's first 10GbE switch based on RISC-V open architecture. The device is called Milk-V Vega: it is designed for use in broadband access networks, video surveillance and audiovisual services platforms, smart city systems, and so on.
The RISC-V-chip FSL1030M developed by Wuhan Binary Semiconductor Corporation is used. The product operates at a frequency of 400 MHz and has a 1.5 Mbyte cache. The Linux kernel OS is used as a software platform. Milk-V Vega has two 10GbE SFP+ ports, four 1GbE SFP connectors and eight 1GbE RJ-45 ports. Two units can be mounted side by side in a standard server rack.
The processor part is based on the UX608 uCore (Nuclei System Technology) core. RV32/64 IMACFDPB instruction set, AHB-Lite, ILM/DLM interfaces, etc. are supported. A customizable SRAM for instructions and data is provided. The chip configuration includes Cluster Cache in addition to ICache instruction and DCache data caches. JTAG and cJTAG interfaces are supported.
The Chinese switch chip (L2) FSL91030M used in the device provides support for eight Gigabit PHY ports (10/100/1000BASE-T and 100BASE-FX), two 10G SerDes ports (1000BASE-X, SGMII, QSGMII, O-USGMII and 10G BASE-R) and four 1G SerDes ports (1000BASE-X and SGMII). Four combined 1G SerDes and 1 GbE PHY ports are possible. In addition, the FSL91030M allows two ports to be used as expandable RGMII/GMII/MII interfaces.
