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.
