PROBLEM TO BE SOLVED: To reduce an imitating scale, and to shorten a processing time in a system of a host processor imitating a target processor. SOLUTION: When checkpoint execution which means a hardware resource update is performed in processing after code conversion, a checkpoint detecting part for detecting the checkpoint execution is provided, and the processing is performed by converted the code (S6) while the execution of the checkpoint is performed. When the host processor detects unexpected exception processing, processing (S8) for restoring the checkpoint immediately before the detected point is performed. COPYRIGHT: (C)2004,JPO
