VxWorks
The World’s Leading Real-Time Operating System for the Intelligent Edge
For nearly 35 years, VxWorks has been used to ensure the security, safety, and reliability you need to design and build mission-critical embedded systems that simply must work.
VxWorks® is the industry’s most trusted and widely deployed real-time operating system (RTOS) for mission-critical embedded systems that must be secure and safe. It delivers a proven, real-time, and deterministic runtime combined with a modern approach to development. Regardless of industry or device type, companies building intelligent edge systems rely on the VxWorks pedigree of security, safety, high performance, and reliability.
VxWorks is a deterministic, priority-based preemptive RTOS with low latency and minimal jitter. It is built on an upgradable, future-proof architecture to help you rapidly respond to changing market requirements and technology advancements.

Huawei LiteOS
Huawei LiteOS is an IoT-oriented software platform integrating an IoT operating system and middleware. It is lightweight, with a kernel size of under 10 KB, and consumes very little power — it can run on an AA battery for up to five years! It also allows for fast startup and connectivity and is very secure. These capabilities make Huawei LiteOS a simple yet powerful one-stop software platform for developers, lowering barriers to entry for development and shortening time to market. Huawei LiteOS provides a unified open-source API that can be used in IoT domains as diverse as smart homes, wearables, Internet of Vehicles (IoV), and intelligent manufacturing. Huawei LiteOS enables an open IoT ecosystem, helping partners to quickly develop IoT products and accelerate IoT development.

MQX RTOS
The MQX real-time operating system (RTOS) provides real-time performance within a small, configurable footprint. The RTOS is tightly integrated with 32-bit MCUs and MPUs from NXP and is provided with commonly used device drivers. The MQX RTOS is designed to have a modern, component-based microkernel architecture allowing for customization by feature, size, and speed by selecting the components engineers wish to include while meeting the tight memory constraints of embedded systems. The MQX RTOS can be configured to take as little as 8 KB of ROM and 2.5K RAM on Arm Cortex M4, including kernel, 2 task applications,1 LW Semaphore, interrupt stack, queues, and memory manager. Provides a fully-functional RTOS core with additional, optional services. Components are linked in only if needed, preventing unused functions from bloating the memory footprint. Key components are included in both full and lightweight versions for further control of size, RAM/ROM utilization and performance options.
