Abstract

PROBLEM TO BE SOLVED: To relieve the load on a CPU and then to improve the processing performance as a result by allowing a process monitor means to monitor the result of a 1st processing means as preprocessing and judges whether or not a 2nd processing means is executed according to the confirmation contents. SOLUTION: The process monitor means 22 which detects the process result when the 1st process means 21 is executed is not actuated at the same with the 1st processing means 212, namely, only the 1st processing means 21 is executed. Then when the 2nd processing means 23 is executed, the process monitor means 22 is executed to confirm the result of the 1st processing means 21 as preprocessing. According to the confirmation contents, it is judged whether or not the 2nd processing means 23 is executed. Thus, the process monitor means 22 which detects the process end of the 1st processing means 21 is not always executed, but executed when the 2nd processing means 23 is executed to monitor the result of the 1st processing means 21, so the load on the CPU of a data processor is relieved.
