PROBLEM TO BE SOLVED: To prevent data held by a latch prior to the start of interrupting processing from being lost due to the interrupting processing generated in a data processing system where a data bus and a data processing part are each constituted of a dual system. SOLUTION: In this data processing system 10, data processing parts 12a and 12b are able to acquire a pair of reference data(data A and data B) from two data buses 14a and 14b in parallel, and to successively store those data into memories 16a and 16b. Thus, it is not necessary to arrange a latch to temporarily hold data before the data processing parts 12a and 12b like a conventional system. That is, this data processing system 10 is configured to solve a problem wherein data held by a latch prior to the start of interrupting processing are overwritten by the data of interrupting processing like a conventional system.
