PROBLEM TO BE SOLVED: To obtain a data processor capable of executing by the number of times of a designated instruction unit while repeating an instruction included in a prescribed instruction column. SOLUTION: When a repeat finishing flag 903 is not asserted (the unattained state of the instruction execution of the number of execution instructing times), an execution control signal generating part 910 successively generates execution control signals based on an instruction code 907 given via the group of data latches 908 to execute an instruction regulated by the code 907. When the flag 903 is asserted (the attained state of the instruction execution of the number of execution instructing times), the part 910 negates all the execution control signals regardless of the contents of the code 907 to invalidate all the instructions executed in the period in which the flag 903 is asserted. |
