What is RTOS?A certain capability within a specified time constraint is guaranteed by an operating system called ‘real time operating system’. For example, certain object availability for a robot when it is assembled is ensured by a real time operating system. For making an object available within a designated time, the operating system would terminate with a failure. This is called a ‘hard’ real time operating system. The assembly line will be continued for functioning, but the output of production might be lower as the objects appearance is failed in a designated time, which causes the robot to be temporarily unproductive. This is called ‘soft’ real time operating system. Some of the real time operating systems qualities can be valuated by operating systems such as Microsoft’s Windows 2000, IBM’s OS/390 up to some extent. It means that, if an operating system does not qualify certain characteristics of the operating system enables to be considered as a solution to a certain real time application problem.
There is a requirement of real time operating system in small embedded systems which are bundled as part of micro devices. The requirements of real time operating systems are considered for some kernels. Since device drivers also needed for a suitable solution, a real time operating system is larger than just a kernel.
