Abstract

The distributed computer systems applied in industry are usually of the real-time type. In those systems the maximal system response time has to be always well known in order to ensure the functional as well as the safety parameters of the system. However, the system response time may be subject to change as a result of system development during its life cycle. As the given system grows, the response time lengthens. So it happens that in order to satisfy the real-time constraints, the response time TRES has to be reduced after the system development. One of the factors that have an influence on the TRES time, is the automata cycle of the communication system nodes. The shorter the automata cycle is, the more frequent is the data exchange between the CPU module and the communication module of the given system node, which improves the TRES value. However, having the node’s application well implemented, shortening of the automata cycle may seldom be done by the application optimization. Then, the only solution would be to temporary shorten the automata cycle by execution of some of the most crucial parts of the user application. In this paper, a method for shortening the automata cycle is described.
