VxWorks is a real-time operating system developed as proprietary software by Wind River Systems, a wholly owned 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 and defense, medical devices, industrial equipment, robotics, energy, transportation, network infrastructure, automotive, and consumer electronics.
An embedded operating system is an operating system for embedded computer systems. Embedded operating systems are computer systems designed for a specific purpose, to increase functionality and reliability for achieving a specific task. Resource efficiency comes at the cost of losing some functionality or granularity that larger computer operating systems provide, including functions which may not be used by the specialized applications they run. Depending on the method used for multitasking, this type of OS is frequently considered to be a real-time operating system, or RTOS. Embedded systems are mostly used as Real-time operating systems.
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 It has been superseded by the Nucleus RTOS.
MontaVista Software is a company that develops embedded Linux system software, development tools, and related software. Its products are made for other corporations developing embedded systems such as automotive electronics, communications equipment, mobile phones, and other electronic devices and infrastructure.
The LynxOS RTOS is a Unix-like real-time operating system from Lynx Software Technologies. Sometimes known as the Lynx Operating System, LynxOS features full POSIX conformance and, more recently, Linux compatibility. LynxOS is mostly used in real-time embedded systems, in applications for avionics, aerospace, the military, industrial process control and telecommunications. As such, it is compatible with military-grade security protocol such as wolfSSL, a popular TLS/SSL library.

Multiuser DOS is a real-time multi-user multi-tasking operating system for IBM PC-compatible microcomputers.
The ITRON project is the first of several sub-architectures of the TRON project.
An operating system abstraction layer (OSAL) provides an application programming interface (API) to an abstract operating system making it easier and quicker to develop code for multiple software or hardware platforms.
PikeOS is a commercial, hard real-time operating system (RTOS) that offers a separation kernel based hypervisor with multiple logical partition types for many other operating systems (OS), each called a GuestOS, and applications. It enables users to build certifiable smart devices for the Internet of things (IoT) according to the high quality, safety and security standards of different industries. For safety and security critical real-time applications on controller-based systems without memory management unit (MMU) but with memory protection unit (MPU) PikeOS for MPU is available.
Novell Embedded Systems Technology (NEST) was a series of APIs, data formats and network protocol stacks written in a highly portable fashion intended to be used in embedded systems. The idea was to allow various small devices to access Novell NetWare services, provide such services, or use NetWare's IPX protocol as a communications system. Novell referred to this concept as "Extended Networks", and when the effort was launched they boasted that they wanted to see one billion devices connected to NetWare networks by year 2000. NEST was launched in mid-1994 countering Microsoft's similar Microsoft at Work efforts, which had been launched in 1993.
Lynx Software Technologies, Inc. is a San Jose, California software company founded in 1988. Lynx specializes in secure virtualization and open, reliable, certifiable real-time operating systems (RTOSes). Originally known as Lynx Real-Time Systems, the company changed its name to LynuxWorks in 2000 after acquiring, and merging with, ISDCorp, an embedded systems company with a strong Linux background. In May 2014, the company changed its name to Lynx Software Technologies.
SYSGO GmbH is a German information technologies company that supplies operating systems and services for embedded systems with high safety and security-related requirements, using Linux. For security-critical applications, the company offers the Hypervisor and RTOS PikeOS, an operating system for multicore processors and the foundation for intelligent devices in the Internet of Things (IoT).
FlexOS is a discontinued modular multiuser multitasking real-time operating system (RTOS) designed for computer-integrated manufacturing, laboratory, retail, and financial markets. Developed by Digital Research's Flexible Automation Business Unit in Monterey, California, in 1985, the system was considered to become a successor of Digital Research's earlier Concurrent DOS, but with a new, modular, and considerably different system architecture and portability across several processor families. Still named Concurrent DOS 68K and Concurrent DOS 286, it was renamed into FlexOS on 1 October 1986 to better differentiate the target audiences. FlexOS was licensed by several OEMs who selected it as the basis for their own operating systems like 4680 OS, 4690 OS, S5-DOS/MT, and others. Unrelated to FlexOS, the original Concurrent DOS system architecture found a continuation in successors such as Concurrent DOS XM and Concurrent DOS 386.
LynxSecure is a least privilege real-time separation kernel hypervisor from Lynx Software Technologies designed for safety and security critical applications found in military, avionic, industrial, and automotive markets.
Empress Embedded Database is a relational database management system that has been embedded into applications, including medical systems, network routers, nuclear power plant monitors, satellite management systems. Empress is an ACID compliant relational database management system (RDBMS) with two-phase commit and several transaction isolation levels for real-time embedded applications. It supports both persistent and in-memory storage of data and works with text, binary, multimedia, as well as traditional data.
Actian Zen is an ACID-compliant database management system (DBMS) developed by Pervasive Software. It is optimized for embedding in applications and used in several different types of packaged software applications offered by independent software vendors (ISVs) and original equipment manufacturers (OEMs). It is available for software as a service (SaaS) deployment due to a file-based architecture enabling partitioning of data for multitenancy needs.
