Examples of real time processing

Answer 1

Computer controlled servomechanisms for heat or other environmental maintenance; medical diagnostic and or exam technologies like MRI's, echocardiograms, etc, Doppler weather monitoring, air traffic control systems, some computerized communications technology...

Answer 2

Real time processing is usually found in systems that use computer control.

This processing method is used when it is essential that the input request is dealt with quickly enough so as to be able to control an output properly. The is called the 'latency'.

For example, the computer inside the Engine Control Unit in a car has to manage the engine at every moment based on what the driver wants to do.

Real time processing has to be programmed very carefully to ensure that no input events are missed.

Hard real-time processing refers to a system in which a deadline that must be met. If the deadline is not met, the task or system is considered a failure. This kind of processing can be found in systems with which there is often little room for failure. Some examples may include airplane control systems, pacemakers, and many medical devices that monitor the health of patients who may be in critical condition.

Soft real-time processing, on the other hand, is a kind of processing in which the deadlines may be missed without the system failing because of the delay. In some cases, the system might suffer from poorer quality or decreased effectiveness of functions. These processes are often found in audio and visual systems. A recorded video, for example, might miss frames, though the video will not fail because of the lateness or deletion of certain frames. Instead, the quality of the video is decreased.
