摘要

Access monitoring unit (11), the access signal that is output to the (3) peripheral device from (1) CPU, the access information includes an address that matches the address stored monitoring address setting unit (10) Get access determination unit (13) compares the access information received access monitoring unit (11), and the access information immediately before the stored access storage unit (12), the access information received immediately before if different from the access information, stores access memory unit (12) to access information acquired, and requests the transmission of the exception occurrence notification exception generating unit (14), the access information received is identical to the access information immediately before For, it is excluded from the comparison of the last access information stored access storage unit (12). With this configuration, it can be possible to reduce the amount of processing to be emulated, and to emulate the peripheral devices efficiently.
