Driver

Flow embark multiple drivers.

Coroutine

Drivers are useful to essentially provide asynchronous programming by using coroutines. Thus, this can be implemented in severals ways in most popular programming languages.

Coroutine are very similar to threads and provide concurrency but not parallelism. Advantage of using coroutine :

• this can be a preferred usage to thread for hard-realtime context.
• there is no need for synchronisation primitives such as mutexes, semaphore.
• it reduces the usage of system lock for sharing resources.
