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 ...

Later came source code level debugging, multiprocessing support, and further computer networking extensions. In about 1991, Software Components Group was acquired by Integrated Systems Inc. (ISI) which further developed pSOS, then renamed as pSOS+, for other microprocessor families, by rewriting most of it in the programming language C.
VxWorks is a real-time operating system (or RTOS) developed as proprietary software by Wind River Systems, a subsidiary of Aptiv.First released in 1987, VxWorks is designed for use in embedded systems requiring real-time, deterministic performance and in many cases, safety and security certification for industries such as aerospace, defense, medical devices, industrial equipment, robotics ...
Trace support through generic trace macros. Tools such as Tracealyzer, a commercial tool by FreeRTOS partner Percepio, can thereby record and visualize the runtime behavior of FreeRTOS-based systems for debugging and verification. This includes task scheduling and kernel calls for semaphore and queue operations.
Versatile Real-Time Executive (VRTX) is a real-time operating system (RTOS) developed and marketed by the company Mentor Graphics. VRTX is suitable for both traditional board-based embedded systems and system on a chip (SoC) architectures. It has been superseded by the Nucleus RTOS. [1]
OpenComRTOS uses a uniform architecture with a kernel Task, driver Tasks, and application Tasks, each having a Task input Port. The same interface is used for the Interrupt Service Routines. The underlying architecture relies on the use of prioritised packet switching with communication and routing being part of the underlying system services ...
RTX / RTX64 are real-time operating system (RTOS) by the firm IntervalZero. They are software extensions that convert Microsoft Windows operating system into a RTOS. [ 1 ] It was the first Windows real-time solution on the market.
