Real Time Computing Systems

The real time computing systems respond to input immediately therefore there are strict timing constraints that have to be met to get the correct output. Real time applications are expected to generate output in response to stimuli within some upper bound. Real t ime systems change its state in real time even after the controlling processor has stopped its execution. The real time application respond to the stimuli within a particular deadline. Scheduling is deciding how use the processor’s time on the computer and to provide efficient service to all users i t is an arrangement of performing functions at specified time. The intervals between each function have been defined by the algorithm to avoid any overlapping. The scheduling techniques has been used in order to achieve optimized results in real time. In the paper we analyze various scheduling techniques and observes the various issues on which there is still a need to work.
