Abstract

PURPOSE: To improve the processing capability of a control unit by tabulating an interrupt address determination matrix according to numbers indicating processing request classes from an external unit and state indication numbers designated by a program, by the operation of hardware.
CONSTITUTION: When a processing request occurs in external unit 1, processing request contents discrimination part 4 analyzes processing request contents to generate a processing request indication number after the external unit which generated the processing request is discriminated by processing request unit discrimination part 2. State information storage part 5 reads out a state indication number designated by a program. Combination interrupt address determination part 6 determines an interrupt address on a basis of the inputted processing request indication number and the state indication number and sets the interrupt address to address register 8 to interrupt the program. The interrupted program executes successively instructions, which are stored in memory 9, from the interrupt address. As a result, the load of the program can be reduced to improve the processing capability of the control unit.
