A real-time system is any information processing system which has to respond to externally generated input stimuli within a finite and specified period — the correctness depends not only on the logical result but also the time it was delivered — failure to respond is as bad as the wrong response! Hard real-time systems. Soft real-time systems.

Real-Time Systems

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. In this type of system, processing must be done inside the specified constraints. Otherwise, the system will fail. Why use an RTOS? Here are important reasons for using RTOS: It offers priority-based scheduling, which allows you to separate analytical processing from non-critical processing.

Real-time operating system (RTOS): Components, Types, Examples

Real time system is defined as a system in which job has deadline, job has to finished by the deadline strictly finished. If a result is delayed, huge loss may happen. Hard Real Time System : Hard real time is a system whose operation is incorrect whose result is not produce according to time constraint. For example,. Soft Real Time System : Soft real time system is a system whose operation is degrade if results are not produce according to the specified timing requirement.

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. Event-driven systems switch between tasks based on their priorities, while time-sharing systems switch the task based on clock interrupts. Most RTOSs use a pre-emptive scheduling algorithm.


Hard real time is a system whose operation is incorrect whose result is not produce according to time constraint. 2. Soft Real Time System: Soft real time system is a system whose operation is degrade if results are not produce according to the specified timing requirement.

The Linux kernel, even at its most extreme, uses only soft real-time. This means that, while processor and other scheduling algorithms may be optimized to give preference to higher-priority processes, no absolute guarantee of performance can be made.

Real-Time Systems

Real-Time systems are becoming pervasive. In a Real-Time System the correctness of the system behavior depends not only on the logical results of the computations, but also on the physical instant at which these results are produced.

Что ж, попробуйте! - Он начал нажимать кнопки мобильника.  - Ты меня недооценил, сынок. Никто позволивший себе угрожать жизни моего сотрудника не выйдет отсюда.  - Он поднес телефон к уху и рявкнул: - Коммутатор. Соедините меня со службой безопасности.

 С какой целью. - Танкадо мог посылать фиктивные сообщения на неиспользованный адрес в надежде, что мы его обнаружим и решим, что он обеспечил себе защиту. В таком случае ему не нужно будет передавать пароль кому-то. Возможно, он работал в одиночку. Стратмор хмыкнул.

Клушар увидел яркую вспышку света… и черную бездну. Человек ослабил нажим, еще раз взглянул на прикрепленную к спинке кровати табличку с именем больного и беззвучно выскользнул из палаты. Оказавшись на улице, человек в очках в тонкой металлической оправе достал крошечный прибор, закрепленный на брючном ремне, - квадратную коробочку размером с кредитную карту. Это был опытный образец нового компьютера Монокль, разработанного ВМС США для проверки напряжения аккумуляторов в труднодоступных отделениях подводных лодок - миниатюрный аппарат, совмещенный с сотовым модемом, последнее достижение микротехнологии.
