On the Applied Linux & Embedded Internet Show in April 5th, 2001, in Kista,
Sweden, Nicholas MacGuire <der.herr@hofr.at>, from Wien, Austria, presented
a talk on MiniRTL <URL: http://www.thinkingnerds.com>, a minimum real-time
Linux for embedded applications. It boots off a 1.44 MB floppy, requires no
hard disk, and runs with 4 MB memory. People at Finite State Machine Labs,
Inc. <URL: http://www.fsmlabs.com/> wrote the real time Linux kernel
additions <URL: http://www.rtlinux.org/> which the MiniRTL builds on.
The real-time kernel (RTLinux) handles hardware interrupts, runs Linux as
its idle task (U.S. Patent 5,995,745), emulates interrupts to Linux, and
handles timestamps and expensive scheduling. The changes to Linux includes
creation of a RAM MINIX format disk, a special routine (initrd-always) to
set up the RAM disk device and copy files to it from the floppy, and then
boot the RTLinux/Linux combo from the RAM disk.
The RTLinux conforms to POSIX PSE51 1001.13 RT profile.
