1. Real-time application architectures

1.1 Hardware architecture

The type of hardware architecture used to run a real-time application has a major impact not only on the application's software architecture, but also on the means used to temporally validate this system. Systems can be divided into two categories: centralized systems, running on a single chip, and distributed systems, running on a number of remote computers.

Software tools

Various scheduling tools are available, some of which can be downloaded free of charge from the Internet. The two most widely used free tools are :

MAST (Modeling and Analysis Suite for Real-Time Applications) is a tool developed by the University of Cantabria in Spain. In particular, it can be used to calculate worst-case response times on single-core, centralized or distributed...
