PROBLEM TO BE SOLVED: To provide an instruction scheduling device for generating an instruction string to prevent delay of processing so as to reduce register use time.SOLUTION: The instruction scheduling device includes: an instruction grouping part 2 for grouping instructions in an instruction block into instruction groups each of which includes a series of instructions in dependence relation; a priority setting part 3 for setting an instruction unit priority that shows processing priority in the instruction groups including the instructions with respect to each instruction, and setting the instruction group-based priority which shows the processing priority in the instruction block with respect to each instruction group; and an instruction scheduling part 4 for scheduling the instructions included in the instruction groups, on the basis of the instruction unit priority, in order from the instruction group with the higher instruction group-based priority, and arranging the instructions included in the instruction groups with the second higher instruction group-based priority, on the basis of the instruction unit priority, in a processing cycle for performing parallel execution of the instructions of other instruction groups by a real machine among the processing cycles with the instructions in the instruction groups arranged therein. |
