PROBLEM TO BE SOLVED: To provide a processor which holds compatibility with a general processor by means of a former technology, which can flexibly correspond to system extension and which speeds up a processing corresponding to interrupts. SOLUTION: In a processor 100, an interrupt execution control part 103 analyzes an interrupt cause, outputs information showing the storage position of a corresponding processing procedure and an entry address holding part 106 holds it as an entry address. When an instruction execution control part 101 gives an instruction to use the entry address, a selector part 108 selects it and outputs it to an instruction address holding part 109 and a corresponding processing is caused to be executed.
