PROBLEM TO BE SOLVED: To provide an interruption discrimination circuit by which time to be spent on discrimination of interruption factors can be shortened and interruption levels can be simultaneously selected by every interruption factor. SOLUTION: In a sequential instruction reading type computer, it is provided with a correlation means for correlating a plurality of branching destination information registers with a single address in a program memory space, a branching destination information register switching means for correlating the branching destination information registers with the single address by switching them, an interruption input means, and an interruption flag means for setting an interruption flag by interruption input. The branching destination information registers are switched by the interruption flag. In addition, branching instructions are stored in the branching destination information registers. Furthermore, branching destination addresses are stored in the branching destination information registers. COPYRIGHT: (C)2003,JPO
