Quintauris Introduces Altair: The Unified RISC-V Profile for Embedded Systems

March 3, 2026 -- Quintauris, a leading provider of RISC-V solutions, today announces Altair, the profile specification that defines a stable, binary-compatible RISC-V foundation for embedded systems.  

By precisely defining mandatory and optional ISA extensions, privilege modes, and execution assumptions, the profile guarantees long-term binary compatibility across compliant implementations, addressing fragmentation while preserving architectural flexibility. 

Intentionally designed for MCU-class systems, Altair delivers the consistency required for industrial, automotive, and real-time embedded deployments where product lifecycles span a decade or more.

Reducing fragmentation while preserving innovation 

By providing a clear specification of mandatory and optional RISC-V extensions to eliminate architectural uncertainty and establish a consistent baseline across vendors, it defines clear privilege modes architecture to ensure predictable RTOS and firmware behavior.

With binary compatibility as a foundational principle, applications following Altair Profile enable binary compatibility at CPU level across compliant implementations, protecting long-term software investments and enabling true cross-vendor portability.

The Altair profile specification strengthens the software ecosystem around embedded RISC-V and reduces effort for compilers, RTOS, and software stack providers to optimize once and scale broadly.

It delivers the stability required for efficient, resource constraint, safety-conscious, and long-lifecycle deployments.

Accelerating Industrial-Grade RISC-V Adoption 

Altair allows semiconductor vendors to differentiate at the microarchitectural level while adhering to a common execution profile. This balance between standardization and innovation is essential for industrializing embedded RISC-V and enabling ecosystem-wide scalability. 

“Altair represents a foundational milestone in making embedded RISC-V truly production-ready,” said Angel Berrio, Chief Product Officer at Quintauris. “By guaranteeing long-term binary compatibility and defining a stable execution profile, we are enabling software portability at scale an essential requirement for automotive and mission-critical embedded systems.” 

The Altair profile specification will be introduced at embedded world 2026 through a presentation on March 12th by Angel Berrio, CPO at Quintauris.
