PURPOSE:To analyze an optional program, by previously saving the relevant program or data in an auxiliary storage device and detecting the difference between the stored content and a program or data executed and processed on a main storage device. CONSTITUTION:The content (program or data) of a main storage device 10 is previously transferred to a fixed area of an auxiliary storage device 20 and an analyzer 30 compares the program or data of the main storage device 10 with a program or data saved in the auxiliary storage 20. The compared result is outputted to an output device 50 through an output controller 40. The relative address of a program and data to be analyzed is held in an address register 301 and is converted into the address of the main storage device 10, and then, a relevant program or data is fetched into a register 304. Simultaneously, the program or data previously saved in the auxiliary storage device 20 is fetched into a register 305 and compared by a comparator 306.
