Method of operating a data processing system

摘要

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.
