Real-time System is a system that is put through real time which means response is obtained within a specified timing constraint or system meets the specified deadline. Real time system is of two types — Hard and Soft. Both are used in different cases. Hard real time systems are used where even the delay of some nano or micro seconds are not allowed.

Soft real time systems provide some relaxation in time expression. Characteristics of Real-time System: Following are the some of the characteristics of Real-time System:. Attention reader!

Last Updated : 04 May, Characteristics of Real-time System: Following are the some of the characteristics of Real-time System: Time Constraints: Time constraints related with real-time systems simply means that time interval allotted for the response of the ongoing program.

This deadline means that the task should be completed within this time interval. Real-time system is responsible for the completion of all tasks within their time intervals. Correctness: Correctness is one of the prominent part of real-time systems. Real-time systems produce correct result within the given time interval. If the result is not obtained within the given time interval then also result is not considered correct. In real-time systems, correctness of result is to obtain correct result in time constraint.

Embedded: All the real-time systems are embedded now-a-days. Embedded system means that combination of hardware and software designed for a specific purpose. Real-time systems collect the data from the environment and passes to other components of the system for processing.

Safety: Safety is necessary for any system but real-time systems provide critical safety. Real-time systems also can perform for a long time without failures.

It also recovers very soon when failure occurs int he system and it does not cause any harm to the data and information.

Concurrency: Real-time systems are concurrent that means it can respond to a several number of processes at a time. There are several different tasks going on within the system and it responds accordingly to every task in short intervals. This makes the real-time systems concurrent systems.

Distributed: In various real-time systems, all the components of the systems are connected in a distributed way. The real-time systems are connected in such a way that different components are at different geographical locations. Thus all the operations of real-time systems are operated in distributed ways. Stability: Even when the load is very heavy, real-time systems respond in the time constraint i.

You all must have this kind of questions in your mind. Below article will solve this puzzle of yours. Just take a look.

The hardware infrastructure that provides the support of ubiquitous embedded computing may be shared by different applications. Many of those applications have real-time requirements, where events from the environment require the reaction of the computing system. The meeting of deadlines is hindered by the fast system dynamics. At the same time, the embedded system must deal with overload situations.

Real-time operating system RTOS is an operating system intended to serve real time application that process data as it comes in, mostly without buffer delay. It is time-bound system that can be defined as fixed time constraints.

A real-time operating system RTOS is an operating system OS intended to serve real-time applications that process data as it comes in, typically without buffer delays. Processing time requirements including any OS delay are measured in tenths of seconds or shorter increments of time. A real-time system is a time-bound system which has well-defined, fixed time constraints. Processing must be done within the defined constraints or the system will fail. They either are event-driven or time-sharing.

This book is a rich textbook for introducing diverse aspects of real-time systems including architecture, specification and verification, scheduling and real world applications. It is useful for advanced graduate students and researchers in a wide range of disciplines impacted by embedded computing and software. Since the book covers the most recent advances in real-time systems and communications networks, it serves as a vehicle for technology transition within the real-time systems community of systems architects, designers, technologists, and system analysts. Real-time applications are used in daily operations, such as engine and break mechanisms in cars, traffic light and air-traffic control and heart beat and blood pressure monitoring. This book includes 15 chapters arranged in 4 sections, Architecture chapters , Specification and Verification chapters , Scheduling chapters and Real word applications chapters

 Привет, это Дэвид.  - Он замолчал, не зная, что сказать. Беккер терпеть не мог говорить с автоответчиком: только задумаешься, а тот уже отключился.

 Диагностика, черт меня дери! - бормотал Чатрукьян, направляясь в свою лабораторию.  - Что же это за цикличная функция, над которой три миллиона процессоров бьются уже шестнадцать часов. Он постоял в нерешительности, раздумывая, не следует ли поставить в известность начальника лаборатории безопасности.
