<p>A multi-processor system includes at least a first processor and a second processor one of which performs data processing of successive processing steps. The processing processor transfers result data to the other processor each time a data processing step is completed, and the latter processor stores the transferred resultant data. Programs are segmented by respective predetermined breakpoints for a job. When the processing processor is in an abnormal condition, the other processor takes over the job from the nearest breakpoint by utilizing the last transferred result data. The arrangement requires a simpler interface than a fully duplicated redundantly operated system whilst providing rapid transfer when a fault occurs.</p> |
