Windows NT as Real-Time OS?
More and more companies are trying to use Windows NT as a standard Operating System (OS) at all levels of the industrial hierarchy. The use as server and workstation is obvious, but some people want to use it also on the factory floor. These factory floor applications demand real-time system behaviour. Can Windows NT be a component to fulfil this need?
First, we will define what a real-time system is and the OS characteristics we need to allow developers to build such a real-time system. The distinction will be made between hard and soft real-time systems. In the second part, we demonstrate how and why Windows NT cannot fulfil the requirements of a hard real-time system. We show, however, that for some simple soft real-time applications, Windows NT could be used under certain circumstances.
