PROBLEM TO BE SOLVED: To provide a microprocessor provided with high processing capacity at low power consumption. SOLUTION: Program counters (PCs) in the same number as that pipelines or more are prepared, and processing for successively fetching instructions of the address 0 of the PC 1 up to the address 0 of the PC 6 is performed. Then, the processing of fetching an instruction from the address 1 of the PC1 and so forth is performed. By the constitution and the processing, a pipeline stall is not generated in principle.
