According to news from this site on November 6, high-performance RISC-V CPU design company Ventana and Imagination jointly developed heterogeneous CPU-GPU SoC. The two companies will display their simulation models at the RISC-V Summit next week.

According to reports, both companies are major members of the RISC-V International and RISC-V Software Ecosystem (RISE) projects, and both Is a strong advocate of open architecture.

Ventana Micro Systems was founded in 2018 and its first product is the Veyron V1, launched at the RISC-V Summit in December 2022. Ventana will launch Veyron V2 next week, and this joint innovation is expected to be around this goal.

It is said that the main change in V2 compared to V1 is that RISC-V ISA will have most of the necessary features to compete with x86/Arm, such as standards Vector extensions and IOMMU specifications. It will include:

  • Hypervisor extension
    Type 1 and Type 2 hypervisors; nested virtualization

  • Advanced Interrupt Architecture (AIA)

  • Includes native MSI handling and interrupt virtualization

  • Debugging can be divided into external debugging and automatic Managed debugging, memory tracking is also a way of debugging

  • The content that needs to be rewritten is: rich performance events and performance counters
