What is RTOS operating system? Outstanding Features of RTOS

RTOS is the operating system commonly used on microcontroller devices, typically smart watches. Let’s find out what RTOS is and how it works through the following article of Tnhelearning.edu.vn!

About RTOS

RTOS operating system has the English name as Real-time Operating System. This is the operating system used for timing applications, supporting super-fast processing because there is no delay from the cache.

RTOS is super fast with no buffering delay

Classification of operating systems RTOS

RTOS is divided into 3 main types:

• Hard RTOS: Responsible for ensuring tasks are completed within a fixed amount of time and without errors.
• Soft RTOS: Has the task of performing tasks within the allowed scope and on time specified.
• Firm RTOS: Ensures the execution of tasks is always successful even in the case of exceeding the specified time.

Normally RTOS operating system will have 3 main types: Hard RTOS, Soft RTOS, Firm RTOS

RTOS operating system

The RTOS operating system is a program segment that is responsible for resolving, coordinating tasks, creating schedulers, and prioritizing. All of this is made possible by Event-driven event-driven mechanics and Time-sharing.

Where the event-driven mechanism will navigate the tasks depending on the priority, while the time sharing will do the switching task.

Functions of the RTOS . operating system

RTOS has 3 main functions including

• Scheduler : includes 3 default states: Ready to run (preparing tasks), Running (tasks are executing), Blocked (tasks that do not have enough resources to process are transferred and status). lock up).
• Real Time Services : includes 5 services, which are interrupt handling services, time services, device management services, and device management services. memory management services and connection management services (IO services).
• Synchronization and Messaging : includes 3 messages: semaphores (synchronize access rights for shared resources), event flags (synchronize the operation of coordinated tasks), and finally, mailboxes, pipes, message queues (manage sent messages)

RTOS owns many useful functions for users

Advantages of RTOS

Some of the outstanding advantages of the RTOS operating system are:

• Small size, low cost.
• Quite stable, high reliability, can operate on its own for a long time without human intervention.
• RTOS is almost error-free and if it does, it will be easy to detect.
• Good performance, low memory consumption so it doesn’t consume a lot of resources or RAM.

The outstanding advantage of RTOS is its small size and low cost

Applications of RTOS

RTOS operating system is used and applied in many fields such as command control system, air traffic control system, airline reservation system, network multimedia system, robotics, equipment, etc. microcontrollers, IoT healthcare devices,…

In addition, some modern technology devices using RTOS operating system such as Samsung Galaxy Fit R370 smart bracelet, Samsung Galaxy Fit2 smart bracelet, Samsung’s intensive health monitoring device, smartwatch, etc. ..

Many smartwatch devices today also use the RTOS operating system

Difference between RTOS operating system and normal operating system

In daily life we often use operating systems such as iOS, Android, Linux, Windows, etc. When starting up we need to wait for a long time to load.

The RTOS operating system is designed for operations that require rapid system response , often embedded in microcontroller devices, without an interface to interact with the user. And most of these tasks involve machines and technology.

Hopefully with the information about RTOS operating system and outstanding features of RTOS to choose the right watch product for you. Leave a comment if you have any questions!
