embOS (Real-Time Operating System)

embOS is a priority-controlled real time operating system, designed to be used as foundation for the development of embedded real-time applications. It is a zero interrupt latency*, high-performance RTOS that has been optimized for minimum memory consumption in both RAM and ROM, as well as high speed and versatility. Throughout the development process of embOS, the limited resources of microcontrollers have always been kept in mind. The internal structure of embOS has been optimized in a variety of applications with different customers, to fit the needs of different industries. embOS is fully source-compatible on different platforms (8/16/32 bits), making it easy to port applications to different CPUs. Its' highly modular structure ensures that only those functions that are needed are linked, keeping the ROM size very small. Tasks can easily be created and safely communicate with each other using a complete palette of communication mechanisms such as semaphores, mailboxes, and events. Interrupt Service Routines (ISRs) can also take advantage of these communication mechanisms.

Note:  High priority interrupts are never disabled by embOS.

- Context Switching Time


  • Preemptive scheduling: Guarantees that of all tasks in READY state, the one with the highest priority executes, except for situations where priority inversion applies.
  • Round-robin scheduling for tasks with identical priorities.
  • Preemptions can be disabled for entire tasks or for sections of a program.   
  • No configuration needed
  • Up to 255 priorities: Every task can have an individual priority => the response of tasks can be precisely defined according to the requirements of the application.
  • Unlimited number of tasks (limited only by available memory).
  • Unlimited number of semaphores (limited only by available memory).
  • Unlimited number of mailboxes (limited only by available memory).
  • Size and number of messages can be freely defined.
  • Unlimited number of software timers (limited only by available memory).
  • Time resolution tick can be freely selected (default is 1ms).
  • High resolution time measurement (more accurate than tick).
  • Power management: Unused CPU time can automatically be spent in halt mode, minimizing power consumption.
  • Full interrupt support: Most API functions can be used from within the Interrupt Service Routines (ISRs).
  • Zero interrupt latency time.
  • Nested interrupts are permitted.
  • Start application and projects (BSPs) for an easy start.
  • Debug build performs runtime checks, simplifying development.
  • High precision per task profiling.
  • Real time kernel viewer (embOSView) included.
  • Very fast and efficient, yet small code.
  • Minimum RAM usage.
  • Core written in assembly language.
  • All API functions can be called from C /C++/assembly.
  • Initialization of microcontroller hardware as sources.
  • BSP for any unsupported hardware with the same CPU can easily be written by user.
