PURPOSE:To obtain an interruption processor having a freedom degree without fixing a specific priority with respect to plural interrupting signals by starting a prescribed interruption processing program in accordance with the combined state of interrupting signals from plural interrupting means causing interruptions. CONSTITUTION:The interrupting means M1 generates the interrupting signal under the prescribed conditions, transmits it to an interruption data output means M5, and simultaneously sends it to an interruption request signal output means M2 in order to report which interrupting means M1 issues the interruption among plural ones. When the interruption data input means M6 of a microprocessor M4 receives the request from said interruption request signal output means M2, it fetches interruption data from the interruption data output means M5. On the basis of the inputted interruption data, a memory means M3 where the execution start addresses of plural interruption processings are previously stored is accessed to select the start address corresponding to the interruption means M1.
