This is a list of real-time operating systems (RTOSs). This is an operating system in which the time taken to process an input stimulus is less than the time lapsed until the next input stimulus of the same type.
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 ...
Multi-Environment Real-Time (MERT) was the first example of a real-time operating system coexisting with a Unix system. MERT relied on traditional virtualization techniques: the real-time kernel was the host operating system (or hypervisor) and Bell Systems Unix was the guest. RTLinux was an attempt to update the MERT concept to the PC era and ...

iRMX – real-time operating system originally created to support the Intel 8080 and 8086 processor families in embedded applications. ISIS , ISIS-II – "Intel Systems Implementation Supervisor" was an environment for development of software within the Intel microprocessor family in the early 1980s on their Intellec Microcomputer Development ...
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. [2]
Real-time computing (RTC) is the computer science term for hardware and software systems subject to a "real-time constraint", for example from event to system response. [1] Real-time programs must guarantee response within specified time constraints, often referred to as "deadlines".
The emphasis is on compactness and speed of execution. FreeRTOS can be thought of as a thread library rather than an operating system, although command line interface and POSIX-like input/output (I/O) abstraction are available. FreeRTOS implements multiple threads by having the host program call a thread tick method at regular short intervals.
