Micro-Controller Operating Systems (MicroC/OS, stylized as μC/OS, or Micrium OS) is a real-time operating system (RTOS) designed by Jean J. Labrosse in 1991. It is a priority-based preemptive real-time kernel for microprocessors, written mostly in the programming language C. It is intended for use in embedded systems.
A synchronous programming language is a computer programming language optimized for programming reactive systems. Computer systems can be sorted in three main classes: Transformational systems take some inputs, process them, deliver their outputs, and terminate their execution. A typical example is a compiler.
The runtime system of the C language is a particular set of instructions inserted by the compiler into the executable image. Among other things, these instructions manage the process stack, create space for local variables, and copy function call parameters onto the top of the stack.
The Embedded Configurable Operating System (eCos) is a free and open-source real-time operating system intended for embedded systems and applications which need only one process with multiple threads. It is designed to be customizable to precise application requirements of run-time performance and hardware needs.
Based on the RCS Reference Model Architecture the NIST has developed a Real-time Control System Software Library. This is an archive of free C++, Java and Ada code, scripts, tools, makefiles, and documentation developed to aid programmers of software to be used in real-time control systems , especially those using the Reference Model ...
Some examples of hard real-time systems: A car engine control system is a hard real-time system because a delayed signal may cause engine failure or damage. Medical systems such as heart pacemakers. Even though a pacemaker's task is simple, because of the potential risk to human life, medical systems like these are typically required to undergo ...
Oracle's HotSpot Java Virtual Machine uses an SSA-based intermediate language in its JIT compiler. [30] Microsoft Visual C++ compiler backend available in Microsoft Visual Studio 2015 Update 3 uses SSA [31] SPIR-V, the shading language standard for the Vulkan graphics API and kernel language for OpenCL compute API, is an SSA representation.

A real-time operating system (RTOS) is an operating system (OS) for real-time computing applications that processes data and events that have critically defined time constraints. An RTOS is distinct from a time-sharing operating system, such as Unix , which manages the sharing of system resources with a scheduler, data buffers, or fixed task ...
