DEVICE FOR INPUT/OUTPUT EMULATION, METHOD FOR EMULATING INPUT/OUTPUT DEVICE AND STORAGE MEDIUM WHICH STORES INPUT/OUTPUT EMULATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To make whole system's operation verification possible under the configuration which does not have any input/output device specified by a microcomputer application system to run debug.;SOLUTION: In the case that an application program issues an instruction to access the input/output device on the reference program which does not have the specified input/output device, the instruction generates interruption on the microcomputer by using a device access detecting means and is transferred to the host computer, and then the input/output emulator simulates the action.;COPYRIGHT: (C)2001,JPO
