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 advantage of using PIC than other micro controllers?

The advantage of using PIC, rather than other microcontrollers, is PIC has many more features. The microcontrollers are very limited.

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 type of scheduling is there in RTOS?

A scheduler is the heart of every RTOS. It provides the algorithms to select the task for execution. Three common scheduling algorithms are > Cooperative scheduling > Round-robin scheduling > Preemptive scheduling RTOS uses preemptive (priority based) scheduling. In some cases, real-time requirements can be met by using static scheduling.

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.


What are the differences between 8051 and 89c51 microcontrollers?

The instructions used by Atmel 89CXX and 89CXXXX are the same or subset of 8051 microcontrollers.Some of the attractions in going for these microcontrollers include:Fully static operation,flash program memory,less pin count andprecision analog comparator ( in case of 89C20510)Due to many similar features in the architecture and instruction and instruction set as that of 8051, it becomes possible for the 8051 designer to directly start using 89CXX and 89C20XX microcontrollers without any more efforts in learning these microcontrollers.

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.


Advantages and disadvantages of rtos?

RTOS are well... realtime.It means that it is possible to create processes with strict time constraints (like : never more than 5ms delay, the "never" is the important part).The disadvantage is that it will try to meet these time constraints at all costs. Even if it means using less efficient algorithms and completely suspending less critical processes.Because they are often designed for embedded systems, RTOS are usually simpler and smaller than non-RT desktop OSes.


Looking for controller projects?

Due to many impressive features of microcontrollers, any engineering student likes to work on projects based on microcontrollers. So, on this page, we are going to publish a list of mini projects based on microcontrollers. These microcontroller based mini projects are very useful for the engineering students


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 the difference between rtos and OS what are the advantages and disadvantages of rtos?

an RTOS is much better than anormal OS because it is time sensitive, fault tolerable and allow multiprocessing. that are not supported by all OSsA real-time operating system 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 platforma rich set of APIs to save coding time and errorsprocessor housekeeping functionshardware abstraction


Which microcontroller is used mostly in industry 8051 or pic?

8051 is an old microcontroller design. It has been updated and expanded into a family of microcontrollers manufactured by several companies. PIC is not a microcontroller, but is an extensive family of microcontrollers designed and manufactured by Microchip, Inc. Both are quite popular, and there are many other microcontrollers available.
