Zusammenfassung:	PURPOSE:To attain a more detailed analysis of a hardware error which is under emulation by outputting the information obtained at linkage secured to the emulation together with the information obtained at occurrence of the error. CONSTITUTION:When an exception is produced by a misalignment access instruction, the information on a user task is saved. This information is read out when an error occurs during the emulation. If a programming error is confirmed, the information on this error is replaced with the saved information. Meanwhile the information of a hardware error and the saved information are outputted if a hardware error is decided. Thus the abundant information can be acquired even with a hardware error occurred in an emulation state.
