PURPOSE:To perform a program interruption processing without interposing a pre-processing, by starting up a program interruption processing program automatically by referring to an interruption vector area based on a required leading address set at a vector address register and interruption detecting information. CONSTITUTION:The leading address in a program interruption vector area set at the vector address register 1 in a dedicated instruction word and the interruption detecting information from an interruption detection circuit 2 are computed by a computing element 3. The interruption vector area 5 of a main memory 9 corresponding to the program is referred from a computed result via an interruption address fetching part 4. And the area 5 is supplied via a selection circuit 7, and an interruption processing program is taken out from the main memory 9, then, the program interruption processing program is started up automatically. By employing such system it is possible to perform the interruption processing directly and at high speed without interrupting the program and interposing an operating system. |
