PROBLEM TO BE SOLVED: To provide a multiprocessor system which efficiently decides a processor processing an interrupt request from a plurality of processors. SOLUTION: When an interrupt signal T<SB>2</SB>corresponding to the first interrupt request S<SB>1</SB>is accepted by a processor 2<SB>2</SB>, a storage content of a register 14<SB>1</SB>is rewritten from data '1111' of an initial value to data '0001' showing the number of the processor 2<SB>2</SB>. Next, the second interrupt request S<SB>1</SB>is inputted to a decoder 15<SB>1</SB>. Because the data '0001' are stored in the register 14<SB>1</SB>, an assignment part 10A selects an output part 11<SB>2</SB>from a plurality of output parts 11<SB>1</SB>, 11<SB>2</SB>, and inputs an interrupt signal V<SB>2</SB>corresponding to the second interrupt request S<SB>1</SB>.
