Abstract: Method of processing several computer-controlled technical applications. The applications are executed within the same computer working in successive work cycles by allotting thereto during the work cycles at least one time slot of a previously fixed duration. At the end of the time slot allotted to a technical application, a start interrupt is generated which is aimed at starting the execution of another technical application. Each technical application has allotted thereto at least one memory space slot for writing data. The memory space slot is write-inaccessible to the other technical applications so that a technical application which during execution possesses a given level of criticality does not disturb another application having a higher or equal level of criticality.
