IEEE Standard for a Real-Time Operating System (RTOS) for Small-Scale Embedded Systems

This standard is a real-time operating system (RTOS) specification for small-scale embedded systems such as systems with a single chip microcomputer (single chip microcontroller) including 16-bit CPUs, systems with a small amount of ROM/RAM, and systems without a memory management unit (MMU). The RTOS defined in this document is called μT-Kernel. This RTOS specification includes μT-Kernel/OS, which provides the basic functions of RTOS such as scheduling, synchronization, and communication of tasks. The RTOS specification also includes μT-Kernel/SM (System Manager), which provides the extension function for system management.
