Embedded OS RTEMS Turns 21 54

joelsherrill writes "RTEMS is a free real-time operating system for embedded systems. The project is celebrating the 21st birthday of RTEMS today. RTEMS supports the single process with filesystem POSIX profile on over a dozen processor architectures. To just be entering young adulthood, RTEMS has had a busy life. It has been a Google Summer of Code project twice (Thanks Google!). It has been to Venus on the Venus Express, circles Mars on the Electra radio, powers Herschel and Planck, is on its way to the asteroid belt aboard DAWN, and has been a key part of physics discoveries at the Stanford Linear Accelerator Center."

      You laugh, but there's no other signifigance to "21 years". This would have been better celebrated LAST year.

        Why? It's an important time in a young operating system's life -- Throw some 0xDEADBEEF on the registers and bring the free beer, it's party time! Derive safely, RTEMS, and don't BSOD or have unsafe hex while you're out.

    for the inevitable comparisons to Linux. And yes, we've heard of embedded Linux.

      What about embedded Emacs?

      RTEMS targets a different POSIX profile than GNU/Linux. RTEMS provides a single process, multi-threaded environment with either constant or predictable execution times for nearly every service. A small RTEMS system would be 64Kb total code and data space but that would not be the smallest possible. A large RTEMS system with BSP TCP/IP, filesystem, webserver, and telnetd will fit into less than 512Kb code space. This is tiny, if not impossible, for a GNU/Linux system.

    Well, I've been to Venus on the Venus express too, I've circled Mars (but never landed), I've powered her bell and spank, been on my way to a steroid belt aboard Dawn, and I've been a key part of clinic discoveries too. Where's my f**king parade? //Says the gay girl.

    • But are you 21 and is it your birthday?

    • been on my way to a steroid belt aboard Dawn

      Is that like a fashion piece that dispenses drugs around the midsection?

    • If I understand half of what you said, which I think I do but might be wrong, I'd have to surmise that any parade involving fornication would be modded "redundant" anyway. :)

    • Pics or it didn’t happen! ^^

      Oh, and when you find that one girl on Slashdot... she’s gay... I don’t even know what to say to that anymore... ^^

        She's not the only girl here. There's another girl who mentioned she was a fat lady, so I offered to buy her a beer and she took me up on it.

        Unfortunately the straight, heavy woman lives in Australia, which is about as far from Springfield as you can get without leaving the planet :(

    • Well, I've been to Venus on the Venus express too, I've circled Mars (but never landed), I've powered her bell and spank, been on my way to a steroid belt aboard Dawn

      But I've never been to me.

  • RTEMS has seen(and powered the embedded systems of) attack ships on fire off the shoulder of Orion.
  • Congratulations, Joel! Nice to hear RTEMS is still kicking.

      Jake.. 2009 was one of the most active years yet. The Google Summer of Code students were absolutely wonderful. I have pushed on test coverage to get as close as possible to 100%. Santosh was the GSoC student who worked with me and we got test reports near 100% on 5 target architectures (x86, sparc, powerpc, arm, and m68k/coldfire).
  • Yay! Its party time and I am extremely proud to have been part of RTEMS :-) Thanks to Google Summer of Code!
