Abstract

An emulator for use in a multi-process environment for simulating a computer and supporting testing of software, where the emulator detects a first event corresponding to a desired process on the basis of process information; detects a second event corresponding to a desired address on the basis of address information; stores in a memory the output of the first event and sets the output of the first event in the memory, when the desired process is being operated and resets the content in the memory, when a process, which is not desired, is being operated, such that the emulator can detect a final desired event on the basis of both the process information and the address information.
