With the surging popularity of the Internet of Things, you may have heard a lot of talk about RTOS’s. But what are they, exactly?. Given below difference between RTOS and GPOS. RTOS – Real time operating system. it is dedicated to a single work; flat memory model. In a GPOS, the scheduler typically uses a fairness policy to dispatch threads and processes onto the CPU. Such a policy enables the high overall throughput.

Difference between RTOS and GPOS | Aswin’s Blog

A GPOS is made for high end, general purpose systems like a personal computer, a work station, a server system etc. Some kernels can be considered to meet the requirements of a real-time operating system.

Fill in your details below or click an icon to ros in: Lets take the case of task scheduling first.

Before going deep down, it will be good if you read this article from Howstuffworks- about Operating Systems. Normally, in OS terminology, we call this kind of signals interrupt. An RTOS is used for time critical systems.

Its a different topic alltogether.


Discuss to Learn: Difference between RTOS and GPOS (General Purpose Operating Systems)

This ensurers the fairness with which programs are executed. All other service requests are treated as external processes and threads.

For example, an operating system might be designed to ensure that a certain object was available for a robot on ggpos assembly line. Many Embedded interviewer ask this question. Here throughput means — the total number of processes that complete their execution per unit time.

What is the main difference between GPOS and RTOS?

And most naive answer you could come up with is ‘ROTS differsnce fast’. Here a high priority process gets executed over the low priority ones. Scheduler flexibility enables a wider, computer-system orchestration of process priorities, but a real-time OS is more frequently dedicated to a narrow set of applications.

You are commenting using your Facebook account. RTOS guarantee you diffrence particular operation would complete at the worst this much time. Email required Address never made public.

It does not have any upper bound. Some real-time operating systems are created for a special application and others are more general purpose. Well, never use these words. A high priority process execution will get override only if a request comes from an even high priority process. Google it, Mars Path finder robot has this problem. So preemptive kernel is must. Google betwefn, Mars Path finder robot has this problem.


In highly time constraints RTOS system this delay could be devise. So an ATM is a time critical system. To sum up interrupt latency comes from 1.

What’s The Difference Between A RTOS And A GPOS?

Disabling of interrupts spin lock etc 2. Here a high priority process gets executed over the low priority ones. I betwee tried to go from layman terms to more technical stuff. The card user will not wait 5 minutes at the ATM after he pressed the confirm button.

More appropriate answer would be ROTS are deterministic. After pressing the Ane button of a finished document, there is no particular time limit that the doc should be saved within 5 seconds.

However, since other components, such as device drivers, are also usually needed for a particular solution, a real-time operating system is usually larger than just the kernel.
