Real-time Scheduling Theory and Ada

Real-time systems differ from non-real-time systems in that they react to events of the physical world within a certain duration of time. Such a real-time system monitors and controls external processes, and must react to changes in a timely fashion, sometimes in the order of milliseconds. For simple processes/tasks the response is quick enough, but for many real-time systems that are more complex, a sophisticated coordination is required and rapid response to events becomes challenging.
