Description: The core of a real-time operating system (RTOS) is the central component that manages system resources and process execution. Its primary function is to ensure that critical tasks are completed within specific deadlines, which is essential in applications where timing is a determining factor. Unlike conventional operating systems, which may prioritize overall efficiency and multitasking, the core of an RTOS is designed to provide determinism, meaning the ability to predict precisely when a task will be completed. This is achieved through task scheduling algorithms that assign priorities to processes, ensuring that the most critical tasks are executed first. Additionally, the core manages memory, input/output, and inter-process communication, optimizing the use of limited resources. The architecture of an RTOS core can be monolithic or microkernel, each with its advantages and disadvantages in terms of performance and flexibility. In summary, the core of a real-time operating system is fundamental for the efficient and predictable operation of systems that require fast and reliable responses, such as in various sectors including industrial automation, telecommunications, automotive, aviation, and embedded systems.
