Abstract

The invention relates to a synchronisation and/or data exchange method for secure, fault-tolerant computers. The method enables the synchronisation of or the exchange of data between several individual computers working in parallel. The synchronisation or exchange of data is carried out with interrupt signals and using standard components. The invention also relates to a device for carrying out the inventive method.
