RTXC Quadros is a real time operating system (RTOS) written mainly in the C programming language. It is mainly intended for use in embedded systems.
The RTXC RTOS was originally developed by AT Barrett and Associates in the 1970s. It is currently maintained by Quadros Systems, Inc., of Houston, Texas.
RTXC Quadros comes with a tracing tool which give insight in the runtime dynamics and timing, RTXCview.

Nucleus is a Latin word for the seed inside a fruit. It most often refers to:
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 prioritization in multitasking or multiprogramming environments. All operations must verifiably complete within given time and resource constraints or else fail safe. Real-time operating systems are event-driven and preemptive, meaning the OS can monitor the relevant priority of competing tasks, and make changes to the task priority. Event-driven systems switch between tasks based on their priorities, while time-sharing systems switch the task based on clock interrupts.
VxWorks is a real-time operating system 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, energy, transportation, network infrastructure, automotive, and consumer electronics.
An Embedded Operating System (EOS) is an operating system designed specifically for embedded computer systems. These systems aim to enhance functionality and reliability to perform dedicated tasks. When the multitasking method employed allows for timely task execution, such an OS may qualify as a real-time operating system (RTOS).
TRON is an open architecture real-time operating system kernel design. The project was started by Ken Sakamura of the University of Tokyo in 1984. The project's goal is to create an ideal computer architecture and network, to provide for all of society's needs. For different scenarios, the need for different OS kernels was identified.
Nucleus RTOS is a real-time operating system (RTOS) produced by the Embedded Software Division of Mentor Graphics, a Siemens Business, supporting 32- and 64-bit embedded system platforms. The operating system (OS) is designed for real-time embedded systems for medical, industrial, consumer, aerospace, and Internet of things (IoT) uses. Nucleus was released first in 1993. The latest version is 3.x, and includes features such as power management, process model, 64-bit support, safety certification, and support for heterogeneous computing multi-core system on a chip (SOCs) processors.
Green Hills Software is a privately owned company that builds operating systems and programming tools for embedded systems. The firm was founded in 1982 by Dan O'Dowd and Carl Rosenberg. Its headquarters are in Santa Barbara, California.
The ITRON project was the first sub-project of the TRON project. It has formulated and defined Industrial TRON (ITRON) specification for an embedded real-time OS (RTOS) kernel.
FreeRTOS is a real-time operating system kernel for embedded devices that has been ported to 40 microcontroller platforms. It is distributed under the MIT License.
ThreadX is a highly deterministic, embedded real-time operating system (RTOS) programmed mostly in the language C. It was originally released in 1997 as ThreadX when Express Logic first developed it, later it was renamed to Azure RTOS (2019) after Express Logic was purchased by Microsoft, then most recently it was renamed again to Eclipse ThreadX (2023), or "ThreadX" in its short form, after it transitioned to free open source model under the stewardship of the Eclipse Foundation.
A regional transmission organization (RTO) in the United States is an electric power transmission system operator (TSO) that coordinates, controls, and monitors a multi-state electric grid. The transfer of electricity between states is considered interstate commerce, and electric grids spanning multiple states are therefore regulated by the Federal Energy Regulatory Commission (FERC). The voluntary creation of RTOs was initiated by FERC in December 1999. The purpose of the RTO is to promote economic efficiency, reliability, and non-discriminatory practices while reducing government oversight.
Baget RTOS is a real-time operating system developed by the Scientific Research Institute of System Development of the Russian Academy of Sciences for a MIPS architecture and Intel board support packages (BSPs). Baget is intended for software execution in a hard real-time embedded systems (firmware).
Xenomai is a software framework cooperating with the Linux kernel to provide interface-agnostic, hard real-time computing support to user space application software seamlessly integrated into the Linux environment.
μT-Kernel is an open source real-time operating system (RTOS) designed for 16- and 8-bit microcontrollers. "μ” in the name stands for "micro" and pronounced as such. It is not pronounced as "mu". It is freely available under T-License.
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.
OpenComRTOS is a commercial network-centric, formally developed real-time operating system (RTOS), aimed mainly at the embedded system market.
RT-Thread is an open-source real-time operating system (RTOS) for embedded systems and Internet of things (IoT). It is developed by the RT-Thread Development Team based in China. RT-Thread is aimed to change the current situation in China that there is no well used open-source real-time operating system in the microcontroller field.
T-Kernel is an open source real-time operating system (RTOS) designed for 32-bit microcontrollers. It is standardized by T-Engine Forum, which distributed it under T-License agreement. There is also a corresponding Micro T-Kernel (μT-Kernel) implementation designed for embedded systems with 16-bit or 8-bit microcontrollers.
Zephyr is a small real-time operating system (RTOS) for connected, resource-constrained and embedded devices supporting multiple architectures and released under the Apache License 2.0. Zephyr includes a kernel, and all components and libraries, device drivers, protocol stacks, file systems, and firmware updates, needed to develop full application software.
