Real-time does not neccessarily mean fast. It only means that tasks take a predictable amount of time. It does NOT say whether the task needs to be ready within 280us or in 3.23h. And there is also the distinction between hard realtime (where the violation of a deadline is catastrophic like in moving tons of cargo) and soft realtime (like audio where violating a deadline only causes a short noise.I've been interested in using the Raspberry Pi for real-time data projects.
Linux is not the right tool for hard realtime with tight, strict requirements. It can be used for soft realtime with somewhat not so tight requirements. You may need additional hardware for dealing with realtime handling of external signals.
