Hard Real-Time Systems • An overrun in response time leads to potential loss of life and/or big financial damage • Many of these systems are considered to be safety critical. • Sometimes they are “only” mission critical, with the mission being very expensive. • In general there is a cost function associated with the system.

What Are Real-Time Embedded Systems What Are Real-Time Embedded Systems? Real-time systems are computer systems that monitor, respond to, or control an external environment. This environment is connected to the computer system through sensors, actuators, and other input-output interfaces. It may consist of physical or biological objects of any form and structure. Often humans are part of the connected external world, but a wide range of other natural and artificial objects, as well as animals, are also possible. The computer system must meet various timing and other constraints that are imposed on it by the real-time behavior of the external world to which it is interfaced. Hence comes the name real time.

Another name for many of these systems is reactive systems, because their primary purpose is to respond to or react to signals from their environment. A real-time computer system may be a component of a larger system in which it is embedded; reasonably, such a computer component is called an embedded system. Applications and examples of real-time systems are ubiquitous and proliferating, appearing as part of our commercial, government, military, medical, educational, and cultural infrastructures.
