RISC-V Breakthrough: SpacemiT Develops Server CPU Chip V100 for Next-Generation AI Applications
HANGZHOU, China , Jan. 8, 2025 /PRNewswire/ -- Recently, SpacemiT, a RISC-V AI CPU company from China , announced breakthrough progress in the development of its server CPU chip SpacemiT Vital Stone® V100. It now provides a complete RISC-V CPU chip hardware and software platform that fully supports server specifications.
RISC-V CPU core X100, AIA and APLIC supporting interrupt virtualization, IOMMU supporting memory virtualization, IOPMP supporting security functions, LPC and eSPI supporting communication with mainstream BMCs, etc.
The 64-bit server-grade RISC-V CPU core X100 delivers a single-core performance of >9 points/GHz on SPECINT2006 at 2.5GHz@12nm. X100 supports the RVA23 Profile, full virtualization (Hypervisor 1.0, AIA 1.0, IOMMU), RAS features, Vector 1.0 extension, vector encryption and decryption, security, 64-core interconnect, and more.
The IOMMU IP adheres to the RISC-V IOMMU architecture specification and the AXI4-Stream DTI interface, supporting configurable DID, PID, virtual address, physical address width, and various levels of translation cache sizes. It can be flexibly integrated into different locations within the SoC bus system to enable distributed peripheral virtualization and accelerator acceleration.
