?What Are Real-Time Embedded Systems
Real-time embedded systems are one of the most exciting and challenging
Areas of computer engineering. Real-time embedded systems are used in a
Wide range of industries, from medical to military applications. Society is
Growing increasingly reliant on embedded systems, but so many people are
Completely unaware of their existence. This guide is here to help you understand
More about this exciting frontier of computing.
?What is a Real-Time Embedded System
When a system needs to respond to an event or a request within a defined time
Frame, it is called a real-time system. These systems are deterministic as they
Need to be predictable and deadline-responsive. when real-time systems are
Embedded, they are called real-time systems. Embedded systems are a combination
Of both hardware and software. they are application-oriented, meaning they are
Computer systems that have a dedicated function within a larger machine or electrical System. Essentially, a real-time system is a subcategory of systems. It has time constraints Such as external events or input stimuli which the system has to respond to in a timely Fashion. There are many examples of real-time embedded systems, from mission-critical Systems like antilocking breaks and aircraft controls to email and mobile systems.
Types of Real-Time Embedded Systems
In other words there are three main types of real-time embedded systems; they are called Hard, firm, and soft. Classifications of real-time systems are based on the timing Constraints of the system.
Hard Real-Time Systems
In this paragraph this type of system is one in which all of the critical processes have to be completed Within a given time frame. these systems are used in addition situations where missing a Time constraint is absolutely unacceptable, for example, in airplanes or missiles and even website tool and design
Soft Real-Time Embedded Systems
Soft real-time systems are used in situations where meeting time constraints is desirable But not essential. for example, email systems and WIFI have soft real-time embedded Systems. Unlike hard system applications, the consequences of missing time constraints Can cause issues, but they are much less severe with a soft real-time embedded system.
Firm Real-Time Embedded Systems
Systems that operate on a spectrum from hard to soft are called firm. It is common for Instance these systems to be programmed so that it is not acceptable to miss a deadline, But when a deadline is missed, the operation being performed immediately loses all value.
Uses of Real-Time Systems
There are various examples and applications of real-time systems that are being used as Fundamental components of commercial, military, medical, educational, and cultural Infrastructures.however examples of real-time embedded systems in use today include:
Vehicle systems for automobiles, railways, aircrafts, and ships *
Traffic control systems for highways, air traffic, and railways *
Manufacturing processes in the customer product, food and beverage industries *
Medical systems such as radiation therapy, heart treatments, patient monitoring *
Military uses, such as missiles, tracking, and command and control*
Communication systems such as radio, telephone, and satellite communications*
Multimedia systems that provide text, graphic, audio, and video interfaces*
Building control systems that look after heating, lighting, locking, or elevator systems*
Computer games
Systems with artificial intelligence or robots*
Space operations such as spaceship launch, monitoring, and space station control*
