RTOS or Real-Time Operating System is an OS intended to serve a real-time app that processes data as it comes in, essentially without buffer delay.

In RTOS, the requirement for processing time is calculated in 1/10th of seconds of time increments. It is a time-bound system, which means that the processing needs to be completed in specified time constraints.

Else, the system fails.

Our zealous team of developers have been working closely in partnership with the world’s top-notch chip companies for over a decade to give you market-leading, high-quality, commercial-grade RTOS and tools. 

FreeRTOS

FreeRTOS is a kind of RTOS that’s designed to be cramped enough to run on a micro-controller.

However, its use is not restricted to just microcontroller apps.

FreeRTOS provides core real-time scheduling functionality, inter-task timing and communication, and synchronization primitives only.

Extra functionality, like networking stacks or command console interface, can be included with the add-on components.

Keil RTX

Keil RTX is a deterministic, royalty-free, Real-Time OS designed for Cortex-M and ARM devices.

It lets you create programs that perform multiple functions simultaneously and aids in creating apps that are better structured and are easier to maintain.

scmRTOS

Single-Chip Microcontroller Real-Time OS is a free minor preemptive Real-Time operating system that’s used with single-chip microcontrollers.

It can run on small uCs with RAM as little as 512 bytes only. The RTOS is written in C++. 

TNKERNEL

TN Kernel is a very fast and compact real-time kernel for embedded 32/16/8 bits microprocessors.

It was inspired by ITRON specs and follows the μITRON 4.0 requirements. 

There are 4 task states in TNKernel- 

RUNNING state

READY state

WAIT OR SUSPEND State

DORMANT state

Choosing an RTOS

An RTOS can be beneficial for your project in many ways.

Before going to an RTOS, make sure that your MCU- based system needs an RTOS solution. 

RTOS solutions are required- 

If you need to run a number of tasks at the same time to meet specified deadlines. 

If high-priority tasks need assurance of immediate execution.

If a timely response is critical for the system and the inactivity or abeyance should be anticipated. 

Consideration for Choosing the Right RTOS

This is where we can help you. We can aid you in making the right choice.

Here are some essential factors that should be considered while choosing an RTOS.

Performance

Unique features 

IT team

Middleware

Performance is the main factor that should be considered for choosing an RTOS.

Real-time OS are different, and they perform differently.

Every RTOS has some unique features that tell how it operates for executing commands.

Hence, the features should be evaluated for your system to work effectively and choosing the RTOS with relevant features is very important.

The right RTOS will favour your IT team by bringing down the labour intensity to focus more on the product differentiators. 

Almost every RTOs feature third-party components or the middleware components that are integrated with it.

It’s critical to evaluate the middleware to guarantee a seamless integration process.
