PURPOSE:To simplify automatic fault processing operation and to facilitate easy confirmation of fault processing function, by producing a pseudo machine error at a time point designated previously within a program. CONSTITUTION:A program instruction given from a main memory 1 is decoded and executed by an arithmetic control circuit 2. A control register 3 receives a control register set signal from the circuit 2 and controls the generation of a machine error. Then a machine error generation control circuit 8 produces a report on said machine error when an overflow detection signal is supplied while the control register output signal given from the register 3 is kept effective. A fault processor 9 performs the error processing in response to the machine error report signal given from the circuit 8. |
