Quintauris has introduced Altair, a RISC-V profile specification tailored for embedded systems, including automotive applications. Altair aims to reduce fragmentation in embedded RISC-V implementations, ensuring long-term binary compatibility and architectural flexibility for semiconductor vendors.

The specification outlines mandatory and optional instruction set architecture extensions, privilege modes, and execution assumptions for MCU-class systems in industrial and automotive sectors. It aims to balance standardization with innovation, promoting scalability within the embedded RISC-V ecosystem. Angel Berrio will present the Altair specification at embedded world 2026 in Nuremberg on 12 March.
