Abstract: Seizable, connection-associated switching devices of various types emit processing requests with different urgency degrees to a central sequential logic system for information which are to be processed with different urgency dependent on type. A limit value which may be set in an occupation rejection device based on the measure of a continuously-measured, momentary sequential logic system load serves as a comparison normal and effects that processing requests are rejected (accepted) when the urgency value is lower than (greater than) the limit value.

Abstract: A method of operating a data processing system having at least two real-time data processors is described. The method permits the processing of tasks with minimal delay. Given tasks may be coupled to one of the data processors, depending on the type of task and which of the processors has been preselected to operate on such tasks. Each of the data processors is continuously monitored for the purpose of continually determining the utilization ratio for each processor. Each processor is assigned a predetermined upper limit value for its utilization ratio, which value lies below the processor's overload limit. If the upper limit value is exceeded, tasks coupled to one data processor are diverted to another data processor. In the other processor the diverted tasks are processed after the program switchover.
