Important Characteristics Of Real Time Software Architecture

Software architecture is for us the continuously evolving set of decisions and architectural patterns that structure our software tools enable transversal attributes such as scalability performance maintainability usability and quality and upon which we can base the efficient development of the best functionality to address the needs of the radio planning market in general and of our customers in particular.

Important characteristics of real time software architecture.

Basically a real time system is characterized by correctness that involves both the logical outputs correctness and timeliness. Environmental control the system analyzes information from a set of sensors that collect data from the system s environment. Key words and phrases. Hard real time system.

It also presents an overview of the specific functions ahd pro cesses of the moss operating system. The design decisions support a desired set of qualities that the system should support to be successful. A generic architecture is derived for four major categories of real time systems. These stakeholders all have their own concerns with respect to the system.

Real time systems architectures are process architectures the system is composed of a number of concurrent processes 9. This paper discusses the principles of software architectures for real time systems. A generic architecture is derived for three major categories of real time systems. The fundamental idea of a real time architecture is based on the concept of feedback used in control engineering.

A critical real time system requires adequate time for processing an external stimulus. Real time system means that the system is subjected to real time i e response should be guaranteed within a specified timing constraint or system should meet the specified deadline. Operating system design real time operating system layered operating system software architecture and process communication. In the end this is the way we view it at mentum.

This paper discusses the principles of software architectures for real time systems. The software architecture of a system or a collection of systems consists of all the important design decisions about the software structures and the interactions between those structures that comprise the systems. Software architecture exhibits the following. Burglar alarm system 11.

This is known as the response time and it lies within a predetermined value in all possible situations. Types of real time systems based on timing constraints. Observe and react process structure 10. Flight control system real time monitors etc.
