High-performance RISC-V CPU

Overview

The second-generation high-performance RISC-V CPU delivers a major leap in compute capability, designed for deployment across data center, automotive, and edge applications. Veyron V2 is available as licensable IP for integration into custom SoCs or as a complete silicon platform.

Engineered as a server-class processor, Veyron V2 exceeds the demands of modern, virtualized, cloud-native workloads. Ventana's IP portfolio includes key system-level components such as a RISC-V-compliant IOMMU and supports standard AMBA interfaces, enabling seamless integration with third-party IP and acceleration blocks.

IP available now.
Silicon platforms launching in early 2026.
