This article will explain in detail the purpose of the real-time operating system. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

The goal of the real-time operating system is to respond quickly. Real-time operating system is an operating system that guarantees to complete specific functions within a certain time limit. Real-time operating system requirements: 1, multitasking; 2, processing process lines that can be prioritized; 3, a sufficient number of interrupt levels.

What is a real-time operating system?

Real-time operating system is an operating system that guarantees to complete specific functions within a certain time limit. Real-time operating system can be divided into hard real-time and soft real-time, hard real-time requires that the operation must be completed within a specified time, which is guaranteed when the operating system is designed, while soft real-time can complete the operation as soon as possible according to the priority of the task. The operating system we usually use can become a real-time operating system after a certain change.

For example, an operating system can be designed to ensure that robots on the production line can acquire an object. In a "hard" real-time operating system, if the computation that makes the object reachable cannot be completed within the allowed time, the operating system will end up with an error. In the "soft" real-time operating system, the production line can still work, but the output of the product will slow down because the product can not arrive within the allowable time, which makes the robot have a temporary non-production phenomenon.

Some real-time operating systems are designed for specific applications, while others are generic. Some general purpose operating systems call themselves real-time operating systems. But to some extent, most general purpose operating systems, such as Microsoft's Windows NT or IBM's OS/390, have the characteristics of real-time systems. That is to say, even if an operating system is not a strict real-time system, they can solve some real-time application problems.

In general, real-time operating systems (RTOS) require:

Multitasking

Process lines that can be prioritized

A sufficient number of interruption levels

Embedded small operating systems that are loaded as part of micro-devices often require real-time operating systems. Some core issues can be considered to meet the needs of real-time operating systems. However, because other components such as device drivers are often required by special methods, a real-time operating system is usually larger than the core.
