TI-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.

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.
