μT-Kernel 3.0 is a real-time OS for small-scale embedded systems such as IoT edge nodes.
- Compliant with the international standard IEEE 2050-2018
IEEE 2050-2018 is an international standard for real-time OSs, "IEEE Standard for a Real-Time Operating System (RTOS) for Small-Scale Embedded Systems." μT-Kernel 3.0 complies with this standard. - High performance and compactness
μT-Kernel 3.0 allows you to use many functions of T-Kernel 2.0. You can easily delete the functions you don't use from the code, reducing memory footprint. - High portability and support for development environments
μT-Kernel 3.0 has been rebuilt from μT-Kernel 2.0 to make it easier to port it to various processors. It is designed to be independent of specific software development environments and tools.
μT-Kernel 3.0 specification can be obtained from the TRON Forum website.
