fixstars/cRTOS

cRTOS is a niche embedded project originating from Fixstars, a company specialized in high-performance computing. While the technical concept of a 'Compound RTOS' (mixing GPOS and RTOS capabilities on a single many-core chip) is complex, this specific repository is effectively stagnant. With only 19 stars and zero activity over the last several years (nearly 6 years old), it lacks the community momentum or developer adoption required to be considered a viable piece of infrastructure. In the current market, this approach has been largely superseded by frameworks like OpenAMP or standardized hypervisor-based solutions (e.g., Xen for Embedded, Jailhouse). Frontier labs have zero interest in this space, but the project faces high displacement risk from semiconductor giants (NXP, STMicro, Renesas) who provide their own proprietary or better-supported open-source AMP stacks. It serves more as a historical reference for many-core resource partitioning than a living project.
