RPMSG is an endpoint based protocol where a server CPU can run a service that listens to incoming messages at a dedicated endpoint, while all other CPUs can send requests to that (server CPU, service endpoint) tuple. The software framework allows users to create different ADAS application data flows involving radar capture, radar processing, video capture, video pre-processing, video analytics algorithms and video display. The Linux Foundation hosts Zephyr under a permissive Apache 2. Turning off the RTOS was an option, but that would nuke Bluetooth and Wi Real-time operating system (RTOS) is an operating system intended to serve real time application that process data as it comes in, mostly without buffer delay. The modular Zephyr RTOS supports multiple architectures, so developers are able to easily tailor a solution to meet their needs. A real-time operating system (RTOS) must be fast and responsive, schedule tasks and manage limited resources, and ensure functions are isolated and free of interference from other functions. Smart devices are becoming more complicated and challenging to manage. Real-time operating systems (RTOS) are designed for real-time applications such as embedded systems, industrial robots, scientific research equipment and others. An application is expected to be partitioned into a small hard-real-time part, which runs in the kernel as one or more RTLinux threads, and the rest of the application, which runs as one or more ordinary Microsoft also introduced new branding today for the ThreadX RTOS technology it acquired when it bought Express Logic in April 2019. You stated "ARM cortex M". Some folks consider Linux built with its real-time extensions an RTOS, others envision something off-the-shelf like VxWorks, and others would include simple schedulers in that definition. The hard real-time property makes it possible to control robots, data acquisition systems, manufacturing plants, and other time-sensitive instruments and machines from RTLinux applications. Applications that link into the microkernel will get hard real-time for interrupt and context switching. It is the only Commercial-off-the-Shelf (COTS) OS to be awarded a Reusable Software Component (RSC) certificate from the FAA for re-usability in DO-178B/C certification projects.
