PURPOSE:To obtain a distributed multiprocessor system which can be coped with various types of applications by transferring and recognizing a handler selection code between an interrupter and an interruption handler in an interruption control sequence. CONSTITUTION:The interrupter 12 detects the 'LOW' of an interruption acknowledge daisy chain line IACK*. After the code of the low order 3 bit of an address line AX coincides with the priority level of an interruption request which said interrupter drives to 'Low' and the 'Low' of a data strobe signal DSO is recognized, the status/ID byte of 8 bits is outputted on a data bus DX. Thereby, the interruption handler 11 reads the status/ID byte from the data bus and opens a reading data transfer bus. |
