“Lineo has released AtomicRTAI, a single floppy disk
installation for real-time Linux. AtomicRTAI builds upon an
earlier single floppy installation disk previously released by
Zentropix. AtomicRTAI includes the latest version of RTAI with
auto-clock detection, combined with performance measurement tools
and several programs that demonstrate hard real-time Linux
operation.”
“An included measurement tool can be used to evaluate the key
RTOS parameters of context switch time — the time taken for the
CPU to stop running one task and to start running another, and
jitter — the timing variance between individual scheduling points
of a periodic task. This allows developers to easily evaluate the
performance of RealTime Linux on their own platform without the
need to extrapolate figures of merit from existing tests.”
“AtomicRTAI also includes LXRT, a feature which allows easy
deployment of hard real-time tasks without strict kernel
dependencies (see reference, below). Hard real-time tasks can
thereby be developed on a desktop PC, using the standard Linux
kernel, and then deployed under AtomicRTAI.”
