PURPOSE:To recognize an operation with high accuracy on the timing or the waveform of a system to be developed by validating only an address signal corresponding to an address in a page of the address signals outputted through an incorporated MMU at the time of switching from a user space to a system space. CONSTITUTION:Only the address signals A0-A11 corresponding to the addresses in the page of the address signals outputted from the incorporated MMU at the time of switching from the user space to the system space are validated. Therefore, a restart in a fixed address space irrespective of the operating mode of the MMU can be attained. Thereby, since the emulation of a user program can be executed by the use of the MMU, a high speed emulation can be attained and the operation recognition with high accuracy on the timing or the waveform of the system to be developed can be executed. |
