PROBLEM TO BE SOLVED: To attain the efficiency of the processing of an asynchronizing signal arriving from a source system in an emulation system. SOLUTION: A comprehensively assigned branch - target register including the address of a code for processing an asynchronizing signal is prepared, and a comprehensively assigned predicate register in which a flag indicating a waiting state for the transmission of the asynchronizing signal to a proper handler can be risen is prepared. When the asynchroniying signal arrives, emulation is interrupted, information related with the asynchronizing signal is recorded, and the flag is risen in the predicate register. Afterwards, the emulation is resumed, and the emulation is stopped when it reaches a point at which the state can be restored, and branching to an asynchronizing signal processing routine is operated by referring to the branch - target register, and the operation of the asynchronizing signal is executed.
