Why embedded systems require rtos?
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 prioritization Abstracts away the complexities of the processor Provides a solid infrastructure constructed of rules and policies Simplifies development and improves developer productivity Integrates and manages resources needed by communications stacks and middleware Optimizes use of system resources Improves product reliability, maintainability and quality Promotes product evolution and scaling A 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.
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 ).
ROM preserves its contents even when the computer is what?
Off ROM (Read Only Memory) is typically used to write permanent data or instructions to a system for use even after the computer is turned off. Examples of ROM are your BIOS and Firmware

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.
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 the rules to be followed by the interrupt routines in rtos?
1)an interrupt routine must not call any rtos function that bmight block the caller inthe future2)an interrupt routine may not call any rtos function that might cause rtos to switch task unless the rtos knows that an interrupt routine is not a task executive.
What is classification of RTOS?
Classification of RTOSRTOS can be classified into three types : Hard RTOS : These type of RTOS strictly adhere to the deadline associated with the tasks. Missing on a deadline can have catastrophic affects. The air-bag example we discussed in the beginning of this article is example of a hard RTOS as missing a deadline there could cause a life.Firm RTOS : These type of RTOS are also required to adhere to the deadlines because missing a deadline may not cause a catastrophic affect but could cause undesired affects, like a huge reduction in quality of a product which is highly undesired.Soft RTOS : In these type of RTOS, missing a deadline is acceptable. For example On-line Databases.

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.
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
