PROBLEM TO BE SOLVED: To provide a vector interrupt system for a reduced instruction set pipelined microprocessor capable of predicting a response time to an interrupt which does not permit prior use. SOLUTION: In a priority vector interrupt system, a priority vector interrupt unit 28 comprises a vector interrupt mask unit 40, a vector interrupt sampler unit 42, a vector interrupt priority filter unit 44, a vector interrupt reset unit 46, a vector interrupt decoder 48, a vector interrupt control unit 50, and a supervisor mode control unit 52.
