Linux Kernel Used

For the I/O-IPC, an RT-Preempt real-time kernel is used. This is a kernel that has
been provided with the corresponding real-time patch. This, as well as the kernel,
is available under GPL on the Internet:
http://www.kernel.org/pub/linux/kernel/projects/rt/.
This real-time extension provides the following advantages:
• Completely priority-controlled processes in the real-time area.
• Possibility for using processes in the user area with the CVS-Scheduler
("Completely Fair Scheduling").
• Prioritization of interrupt processing.
• The system timer is based on dynamic tick.
This way, reaction times in the I/O-IPC are no longer bound to a fixed time
pattern. As a result, cyclic processes can be started in µs.
