What is the difference between the embedded system and RTOS?
An RTOS is an important subset of an embedded system. (See RTOS explanation below) An embedded system has historically been defined as a single function product where the intelligence is embedded in the system. It could be anything from a dishwasher to a hearing aid, if that product includes a microprocessor and software. Many of today's embedded systems are looking more like PCs with user interfaces, touchscreens, displays, keypads and more. Still, these are not general function systems but are designed to perform very specific functions. The processor in these systems are also highly specialized. They are not, generally, the same processor you would find in a PC. A real-time operating system (RTOS) is intended for systems that need to tightly control responsiveness and performance. With an RTOS you can prioritize operations such that the most critical areas of the application get control of the processor exactly when they need it. All other lower priority operations are paused. An RTOS also gives you all of the other advantages of an OS: * a consistent coding platform * a rich set of APIs to save coding time and errors * processor housekeeping functions * hardware abstraction
Weather Rtos is necessary and not necessary in embedded system?
The choice to use a realtime operating system (RTOS) in an embedded system is very subjective. Some developers are more likely to use an RTOS than others would be. This might be because they are familiar with a particular system and very comfortable with implementing it. The advantages are that many components are already implemented and tested in an RTOS, such as time slicing, semaphores, and shared memory. Once a developer is familiar with the quirks of a particular operating system, it can save a lot of development time. The disadvantages can be higher runtime overhead, both in memory usage and execution speed (although this is not guaranteed). If a system is extremely complex, an RTOS is likely to be necessary. For simple systems, an RTOS probably makes the source code less readable and therefore less maintainable.
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.
Advantages and disadvantages of embedded system?
An RTOS is not required for an embedded system but it can offer powerful advantages to the system developer. Without an RTOS the developer must write his own code to handle all of these functions.Enables real-time, deterministic scheduling and task prioritizationAbstracts away the complexities of the processorProvides a solid infrastructure constructed of rules and policiesSimplifies development and improves developer productivityIntegrates and manages resources needed by communications stacks and middlewareOptimizes use of system resourcesImproves product reliability, maintainability and qualityPromotes product evolution and scalingA well-architected RTOS will handle these functions much more efficiently that a programmer could write the code. RTOS developers are expert in how to handle operations with a minimum of processor cycles.

What does the acronym RTOS stand for?
Real-Time Operating System.
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 Web servers work on a RTOS?
Web (HTTP) servers are not RTOS-dependent. They are part of the application layer of a TCP/IP stack. An embedded web server (such as the Quadnet web server offered by Quadros Systems) is licensed as an option for the underlying networking 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 real time operating system RTOS?
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.
