What is RTOS operating system? What stands out? On which devices is RTOS supported?

Perhaps everyone is familiar with the common operating systems that are run on computers such as Windows, macOS or the operating system for smartphones is Android or iOS, then RTOS is a shortened operating system for microcontroller devices. . In this article, I will share some information about the RTOS operating system. Let's see it now!

1. What is RTOS operating system?

RTOS operating system is also abbreviated as Real-time Operating System. This is an operating system (OS) used to serve real-time applications with super-fast data processing capabilities. Since there is no buffer delay.

2. How does RTOS work?

An RTOS is a segment of a program. At that time, the main task of the RTOS is to solve and coordinate tasks, schedule and prioritize them. This can be done using Event Driven and Time Sharing mechanisms.

- Basic functions of RTOS:

+ Scheduler.

+ Real-time service.

+ Synchronization and messages.

- In the Scheduler there will be 3 default states:

+ Ready to run: Prepared status of the task.

+ Running: The status of the task is executing.

+ Blocked: Tasks with insufficient processing resources will be locked.

- Real-time service:

+ Service interrupt handling.

+ Time service.

+ Service management equipment.

+ Memory management service.

+ Connection management service.

- These messages will be used to exchange information between tasks, it includes the following messages:

+ Semaphores: Synchronize access to shared resources.

+ Event flags: Synchronize activities that need coordination.

+ Mailboxes, Pipes, Message queues: Manage sent messages.

3. Advantages of RTOS

The processing speed of RTOS is a big plus, so it will be reserved for devices that require the ability to handle with the lowest possible latency. Its benefits include prioritizing tasks, good multitasking, and shared management of resources. Moreover, it does not require a large amount of resources or RAM.

RTOS operating system is widely used in many industries, IoT healthcare devices (like smartwatch ) or aviation industry.

4. What devices does RTOS support?

RTOS operating system is supported on many devices, usually RTOS operating system is intended for microcontroller devices, IoT healthcare devices.

5. Difference between real-time operating system and normal operating system

Common operating systems such as Windows, Linux, Android, iOS, etc. This is what we often use every day. When opening an application above, you have to wait for it to load for a long time, this waiting does not affect anything. Because most of that software interacts with people, but little interacts with other software or devices or other phones .

Real-time operating systems are designed for operations that require rapid system response, are typically embedded in microcontrollers and do not have an interactive user interface (GUI). Because most tasks involve other devices and technologies, not people. Internal resources are so scarce that even a minor glitch can destabilize the system.

6. Some products run RTOS

Smart bracelet Samsung Galaxy Fit2

Smart bracelet Samsung Galaxy Fit2 is a compact accessory that supports many modern features with a much cheaper price than a Smartwatch. In particular, Samsung Galaxy Fit 2 is a recently launched product line, updated with useful features and improved battery life up to 15 days.
