Hello,
I'm doing my B.S. thesis in the field of real-time system.
The project's goal is to build a railway simulator
that will be used in the Real-Time Programming course
next year (Fall 2001).
For the reason that I like Linux very much, and
Real-Time Linux is free, I choose RTLinux for this project.
I have download the software with some manuals.
The controlling computer will communicate to the simulator computer
via parallel port, both computer will run Real-Time Linux.
I have some things that aren't clear, and I didn't found in manuals:
(Forgive me for the newbie-ness both in RTL and in the field of real-time
computing)
1. What is the highest and lowest priority of a task ?
Can a thread change its priority dynamically ?
2. What is the difference between one-shot clock and periodic clock ?
(There's no explanation in the manual)
3. Can I call a Linux system call ? Of course this will screw up the hard
real-time constraints, but in case ...
Sorry for my English,
thanks in advance
