emBO++: C++OS: An RTOS For Small Embedded Systems Based On C++

A minimal operating system provides not much more than a mechanism to run different tasks and synchronize between them.

Since C++11 even the C++ Standard provides an interface for this, with more in C++20.

C++OS is a proof of concept that implements the C++ Standard API as pre-emptive multitasking system on bare metal. This makes it possible to explore how far the C++ Standard interface can already provide the interface for portable embedded applications and what's still missing.

C++OS also provides a partial preliminary implementation for the executor interface that's currently proposed for C++23. This allows for more task launching control than simply std::thread.

This presentation will present C++OS as it currently exists, what's there and what's still missing. It will also show some comparisons with other approaches.
