PROBLEM TO BE SOLVED: To prevent an oversight of original interrupt processing after completing a later interrupt. SOLUTION: This data processing system uses multiple operating systems, and receives service by the different operating systems. When an original interrupt receives an interrupt by the later interrupt, before executing a main treatment routine in the original operating system, the original interrupt guards itself so that the original interrupt is not overlooked when completing later interrupt treatment by starting a stub interrupt treatment routine in another operating system. Thus, the stub interrupt treatment routine is recognized in the another operating system regardless of the other possible interrupt event, and thus, the interrupted original interrupt treatment can be restarted.
