ELinOS Real-Time -- Industrial Grade Hard Real-Time Linux
[Vendor: Sysgo]

Embedded Linux has gained a massive growth in popularity over the last years. But there are still domains where Embedded Linux is not an option. No hard real-time capability, safety issues, a lack of quality assurance and supportive development tools are the critical arguments. ELinOS Real-Time proves them wrong.

ELinOS Real-Time at a glance
  • Industrial Grade
  • Microkernel based
  • Linux in separate address space
  • POSIX compliant real-time API
  • Integrated application development environment
  • Runs out of the box
  • Available for PowerPC and x86


ELinOS Real-Time enables a concurrent and secure execution of Linux and POSIX applications on a single CPU

Reliable Hard Real-Time

The basis of ELinOS Real-Time is a micro-kernel derived from SYSGO's PikeOS technology. This provides excellent real-time performance combined with proven safety technology used in avionics. Embedded Linux is running in user space, on top of the microkernel, complemented by a POSIX compliant environment for real-time applications. Thus, Linux cannot interfere the execution of the real-time applications. The ELinOS Real-Time toolchain is based on the standard ELinOS quickstart tools to enable an out off the box experience.

Application Development

Developing embedded applications requires different support from the development environment than developing standard applications. Remote debugging, target memory utilization analysis and timing behavior are features an embedded developer almost always needs in addition to standard application development. With CODEO, SYSGO offers a complete development environment for either Linux or POSIX application development.

Service and Support

Providing an outstanding support and a broad range of services was the fundament of the success of ELinOS in the past years. With ELinOS Real-Time we extend this support consequently to serve your needs more precisely. SYSGO strengthens its online support and training capabilities to accommodate the ongoing globalization of project teams.

Reliable Hard Real-Time
  • Kernel -- Provided Kernel includes necessary security patches and is qualified on the supported hardware platforms.
    • Kernel 2.6.15

  • Embedded Linux Configurator -- Graphical front-end for an easy, fast, reproducible and validated embedded Linux configuration.
    • ELK 4.1

  • Supported Hardware -- ELinOS Real-Time is available for PowerPC and x86 architectures.

  • Hard Real-Time -- Linux and POSIX are running in user space of the PikeOS microkernel. They run in separate partitions (memory and I/O secured areas). Thus, Linux can not interfere the execution of the POSIX tasks.

  • POSIX Compliant -- The provided POSIX has a compliant single task, multi-threaded compliant interface (PSE51) that has been tested against the Open Group test suite. Two POSIX tasks can be created, running in separate partitions.

  • Secured IP -- Partitioning provides clear separation between proprietary and Open Source code.

  • Linux to POSIX Communication -- Message queues and shared memory areas are provided to exchanging data. Both mechanisms are configured through the graphical configuration editor ELK.

  • Accessing the Linux File System -- The Linux File System can be accessed from any POSIX task. Provided file access functionalities are:
    • open
    • read
    • write
    • fstat
    • create
    • close

  • Configuration and Application Templates -- Several templates are supplied to provide a fast and easy project start:
    • POSIX to Linux communication
    • Inter-partition data exchange
    • Real-time trace and debug
    • RTC Driver
    • High Resolution Timer
    • etc.

  • Upgrades and Add-ons -- Available ELinOS Real-Time Add-ons:
    • Java real-time runtime environment
    • POSIX PSE52
    • POSIX IPv4/IPv6 TCP/IP Stack
    • Ada real-time runtime environment
    • VXWorks API (instead of POSIX)
    • CoDeSys
    • EtherCAT

Application Development
  • Embedded Application Development -- Developing embedded applications needs special support from the development environment. Direct target connection for remote debugging, timing analysis and to gather runtime information is vital, thus supported by SYSGO's CoTools which are included in ELinOS Real-Time.

  • Application Debugging -- CODEO includes a graphical debugger based on eclipse utilizing the GDB defined by the selected cross tool chain. Register contents, variable values, and breakpoints can be displayed and edited, either for Linux and POSIX.

  • Target Analysis -- CODEO also includes a target analyzing system based on eclipse. The CODEO Trace Tool offers a customizable timing analyzer as well as a target system viewer to display process information, memory utilization, semaphore status and much more.

Service and Support
  • Peer-to-Peer Support -- Support requests are always handled by the ELinOS product team professionals who are able to solve problems live, together with the customer.

  • Training -- SYSGO offers standard trainings such as "Embedded System Development" or "Linux System Programming" as well as customized trainings based on the background and requirements of the customers' trainees.

  • Solution Support -- Telephone and e-mail support for one year is included with every ELinOS Real-Time license.

  • Lifecycle Updates -- Customers can benefit from ongoing improvements, by accessing the SYSGO customer portal where the latest updates of target binaries, new BSPs, and add-ons are available.
