RODOS (Real time Onboard Dependable Operating System) is a real-time operating system for embedded systems and was designed for application domains demanding high dependability.
The first directive of RODOS is "As simple as possible".
We target the "Irreducible Complexity" which is very difficult to reach.
Our target is: every developer shall be able to understand the whole code.
This is important to achieve a very low error number.
RODOS can run as "bare metal": directly on the hardware (it is self-contained) or on the top of other operating systems, like Linux, Posix derivates, RTEMS, FreeRTOS, etc. We have many ports to many different processors, but here only a few are published. In the future more will come.
An important aspect of RODOS is its integrated real-time middleware. Developing the control and payload software on the top of a middleware provides maximal modularity today. Applications/modules can be developed independently, and it is very simple to interchange modules later without worrying about side effects.
RODOS was implemented as a software framework in C++ with an object-oriented application programming interface (API). It is organized in layers: The lowest layer (1) is responsible for control of the embedded system hardware (HAL: Hardware abstraction layer). The next layer (2) kernel: administrates the local resources, threads and time. On top of the kernel we have the middleware (layer 3) which enables communication between building blocks (BB) using a publisher subscriber multicast protocol. And on the top of the middleware the user may implement his applications (layer 4) as a distributed software network of simple BBs. The Building Blocks API on the top of the middleware is a service-oriented interface. BBs interact by providing services to other BBs and using services from other BBs.
