GUIMARÃES, Portugal, May 11, 2026 – OSYX Technologies is bringing Bao Hypervisor support to Andes Technology’s AX66 RISC-V processor IP, marking the first step in a broader virtualization effort across Andes’ processor portfolio. The work gives embedded and edge system developers a static partitioning layer for mixed software domains on AX66-based hardware.
AndesCore AX66 is an out-of-order, application-class multicore processor IP with a 13-stage pipeline. It supports 4-wide decode, 8-wide out-of-order execution, the RVA23 profile, Vector, Vector Crypto, the RISC-V Hypervisor extension (H-extension) and AIA.
Each AX66 core includes 64KB private L1 instruction and data caches, along with up to 1MB private L2 cache. Each cluster contains up to 8 cores and a shared L3 cache up to 32MB.
Bao runs multiple software domains on a single platform, including operating systems and real-time workloads. On AX66-based systems, it supports Advanced Interrupt Architecture (AIA) and Input–Output Memory Management Unit (IOMMU) components for interrupt virtualization, device isolation and integration in complex SoCs.
“Virtualization is becoming a key building block for next-generation compute platforms,” noted Sandro Pinto, co-founder of OSYX Technologies. “Supporting Bao on Andes’ AX66 processors brings production-grade virtualization to a widely deployed RISC-V platform and reinforces a consistent approach to system architecture.”
“Virtualization is critical for modern SoC design, and we are excited to partner with OSYX Technologies to bring the Bao Hypervisor to our AndesCore AX66.” said Dr. Charlie Su, president and CTO of Andes Technology. “By combining our RVA23-compliant hardware with Bao’s static partitioning, we provide customers with a high-performance, secure, and production-ready platform that simplifies the integration of complex real-time and rich OS workloads.”
OSYX and Andes plan to extend Bao Hypervisor support to additional Andes processors with virtualization capabilities. The companies also plan further work on system-level software integration and platform security.
Target platforms include industrial automation, robotics, automotive and mobility subsystems, networking and infrastructure equipment, and intelligent edge devices. These systems combine application processing, AI workloads and real-time control. Both companies also contribute to RISC-V technical working groups covering ISA and system-level specifications.
