<p>PROBLEM TO BE SOLVED: To selectively and efficiently supply a clock to a functioning block in a processor for executing an instruction by pipe-line processing. SOLUTION: This processor is provided with plural functioning blocks whose operations are controlled by a clock signal while at last one of the plural functioning blocks is constituted as an instruction execution functioning block for executing an instruction so that the instruction can be processed by pipe-line processing. This processor is provided with a number of execution clock judging part 8 for judging the number of clocks necessary for operating the instruction execution functioning blocks as the number of execution clocks and a block selecting part 5 for inputting the number of execution clocks judged by the number of execution clock judging part 8, and for selecting the functioning block which supplies the clocks based on the inputted number of execution clocks, and for selecting the instruction execution functioning blocks the number of times of the number of execution clocks when operating the instruction execution functioning blocks.</p> |
