 		 #86827 - Real Time vs Fast
Responding to: ???'s previous message
Erik Malund said:
I do not say do not use a URTOS, what I am saying is : "If you need real time you can not use a real time operating system". Sounds illogical, doesn't it.


This is because you are confusing fast and real. A real time system has to meet specified time deadlines. Whether these deadlines are measured in seconds or nanoseconds does not matter; the point is they have to be met or the system fails in some catastrophic manner.

If your deadlines are nanoseconds or microseconds then I agree - do not use an RTOS, it is not fast enough. For many other applications where deadlines are of the order of milliseconds an RTOS could be applicable.
