Best Answer

RTOS is a real time operating system.The important features are :- - The necessary signalling functions between interrupt routines and taskcodes are handled by RTOS. - It works as an independent system with no internal or external interdependencies. - There are no loop descisions in RTOS - The RTOS can suspend one task code subroutine in the middle order to run another - The time lag is veryless compared to other systems - There are no random time variables, this is good for a direct relationship between instruction and process. - Tasks are simpler to write. - Under most RTOS tasks are simply subroutines.

What type of operation system used in automatic washing machines?

For this kind of appliance, a real-time operating system (RTOS) is the type that has to be used. An RTOS responds to events in real time.


What is a real time operating system used for?

Real Time Operating System (RTOS) aims to serve real time requests. It aims to be fast and not encounter buffering delays on applications and software.


How do you define a process in rtos?

RTOS(Real Time Operating System) can execute multiple programs concurrently. At any time there may be tens of programs executing on a RTOS. A program in execution is called a process. SOMA VARMA G


What are the features of RTOS?

- A RTOS(Real-Time Operating System) has to be multi-tasking and pre-emptible - task priority has to exist - Behaviour of OS should be known - A System of priority inheritance has to exist. - Following parameter should be clearly specified The Interrupt Latency(i.e. time from interrupt arrival to start of execution of ISR) , this has be compatible with application requirements and has to be predictable. RTOS is a real time operating system.The important features are :- - The necessary signalling functions between interrupt routines and taskcodes are handled by RTOS. - It works as an independent system with no internal or external interdependencies. - There are no loop descisions in RTOS - The RTOS can suspend one task code subroutine in the middle order to run another - The time lag is veryless compared to other systems - There are no random time variables, this is good for a direct relationship between instruction and process. - Tasks are simpler to write. - Under most RTOS tasks are simply subroutines.

What is RTOS?

RTOS stands for Real Time Operating System. Typically these are multi-tasking operating systems used in applications where microcontrollers are used to monitor and control embedded systems (e.g. telecom products). Examples include VxWorks, RTLinux.


What are real time operating systems?

A real-time operating system (RTOS)[Generally pronounced as: Or-tos] is a multitasking operating system intended for real-time applications. Such applications include embedded systems (programmable thermostats, household appliance controllers, mobile telephones), industrial robots, spacecraft, industrial control (see SCADA), and scientific research equipment. An RTOS facilitates the creation of a real-time system, but does not guarantee the final result will be real-time; this requires correct development of the software. An RTOS does not necessarily have high throughput; rather, an RTOS provides facilities which, if used properly, guarantee deadlines can be met generally (soft real-time) or deterministically (hard real-time). An RTOS will typically use specialized scheduling algorithms in order to provide the real-time developer with the tools necessary to produce deterministic behavior in the final system. An RTOS is valued more for how quickly and/or predictably it can respond to a particular event than for the given amount of work it can perform over time. Key factors in an RTOS are therefore a minimal interrupt latency and a minimal thread switching latency. An early example of a large-scale real-time operating system was Transaction Processing Facility developed by American Airlines and IBM for the Sabre Airline Reservations System.


Do machines with built in computers use real time operating systems?

Yes, most machines with built-in computers that perform a sequence of tasks in a precise amount of time require a real-time operating system ( or RTOS ).


Which language is used to design a real time operating system?

Maybe C. or Assembler. Linux has some RT capability, and it's written in C. I think VxWorks (a commercial RTOS) is written in C also.


What is the difference between OS and RTOS?

Linux and RTOS are two distinct concepts. Linux is the name given to a specific operating system. An RTOS (Real-Time Operating System) is a specially designed TYPE of Operating System. Where a 'normal' Operating Systems schedule resources/processing time to programs when they are available to the system, whereas an RTOS specializes in allowing programs to run in 'real time', meaning they are able to respond to changes (typically from an external source) as close to instantly as possible. Typically, you would find an RTOS in situations where the computer has to react instantly to changes, such as an industrial control system or systems that monitor and control the power grid. If the operating system prevented the program from responding in a timely fashion, the program would be worthless. Real-time Operating Systems are typically very small, optimized systems, whereas a standard OS is very large, feature-laden and has thousands of different features that run at once. There IS a pared-down version of Linux known as "RTLinux" which falls into the category of an RTOS, but it's not the version of Linux most people are used to seeing. It's very purpose-build, optimized and fast, unusable by anyone but system designers who can work with such an OS.


What is the difference between soft hard RTOS?

hard real time systems are systems that cant tolerate any delay or if delay happens the whole system will be worthless soft real time systems are systems that can tolerate delay In Vechile we are using Hard RTOS. Soft RTOS using in Live telecasting, Flight updation...
