2. Real-time issues
2.1 Definitions
A real-time system is an information system whose corrections depend not only on the logical result of the algorithms, but also on the instant at which these results were produced.
It's not enough for the result to be correct, it has to be achieved within a specified time. The raison d'être of the real-time system is to guarantee that all tasks, in all their execution configurations, will satisfy lower and upper time limits. To guarantee execution times, the system must be predictable. To say that a system is real-time or that it is predictable is virtually the same thing. Thus, "real time" does not mean fast, as is commonly believed. In fact, in a real-time system, slower algorithms with predictable...
