Zusammenfassung:PROBLEM TO BE SOLVED: To reduce the utilization of a RAM and a ROM for issuing a system call without using hardware resources by issuing the system call using an emulator at a system call issue request. SOLUTION: When a target program 8 is executed by a microcomputer in an emulation pod controlled by the emulator 2, the emulator 2 and the system clock interrupting process of an OS kernel as a constituent element of a target program 8 are used through a memory area to send and receive data, and it is determined whether or not there is a system call issue request. When there is a system call issue request, the emulator 2 issues a system call. A user's request to issue a system call is inputted to the front end 10 of a host computer and transmitted to a program on a target by using a RAM area 9 as a memory area.
