RISC-V CPU and AI Computing

RISC-V CPU and AI Computing

SpacemiT K3 integrates eight X100 CPU cores and eight A100 AI cores, delivering 130 KDMIPS and 60 TOPS of AI performance. RVV 1.0, native FP8 inference and multimodal acceleration support offline 30B model inference at over 10 tokens/s for private LLM deployment and low-latency edge AI.

RVA23 and Hardware Virtualization

RVA23 and Hardware Virtualization

The RISC-V platform supports the mainline Linux 7.0 kernel and Chinese-developed operating systems including Deepin, openKylin and OpenHarmony 6.1. RVH 1.0, AIA and IOMMU provide CPU, memory, interrupt and I/O virtualization for isolated workloads and flexible system deployment.

Extensive Connectivity and Hardware Security

Extensive Connectivity and Hardware Security

The standard 170 × 170 mm Mini-ITX board provides four Gigabit Ethernet ports, PCIe 3.0, SATA 3.0, MIPI, DP 1.2, CAN FD and RS485. M/S/U privilege levels, secure boot and hardware-accelerated SM2/SM3/SM4 cryptography support secure edge deployments, alongside hardware protection against side-channel attacks such as Spectre and Meltdown.
