PROBLEM TO BE SOLVED: To facilitate a high-level data analysis by accessing a storage means for various data and an execution result of a CPU and simulating the operation of the CPU, and allocating this storage means in the storage space of a host computer. SOLUTION: A host interface 22a and a communication are tried and when they are normal, a 1st allocating process is performed which allocates an emulation area generating circuit (storage means) 24 to part of the memory space of the host computer 20. Further, a 2nd allocating process is performed which allocates the emulation area generating circuit 24 to the ROM area of a memory map of a target and then a control program for an emulation CPU 24B is loaded from the host computer 20 to the emulation area generating circuit 24. Then a specific command is sent from the host computer 20 to an emulation control part 22 to enter an analytic mode, and then the operation of the target 27 is analyzed under the control of the emulation control part 22b. |
