In recent years, with the rapid development of embedded systems, embedded real-time operating systems are widely used in the manufacturing industry, process control, communication, instrumentation, automobile, ship, aerospace, military, equipment, and consumer products. Nucleus PLUS is a preemptive multi-task operating system kernel designed for real-time embedded applications. 95% of its code is written in ansic, so it is very easy to transplant and supports most types of processors. It is also widely used because of the open source code, convenient development/transplantation, rich functional modules, and ease of cropping of Nucleus PLUS.
This topic series introduces the Nucleus PLUS system architecture, startup process, task scheduling, inter-task communication mechanism, and interruption.
