MICRO PROCESSOR SYSTEM, MICRO PROCESSOR OPERATION ANALYSIS PREVENTING METHOD, AND RECORDING MEDIUM RECORDED WITH MICRO PROCESSOR OPERATION ANALYSIS PREVENTING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a micro processor system by which the analysis of a program on a memory and a bus is difficult so that the operation of the micro processor is not analyzed even if the program is read, and to provide a micro processor operation analysis preventing method and a recording medium in which a micro processor operation analysis preventing program is recorded. SOLUTION: This system is constituted of a micro processor 40, a memory 10 preserving at least a program or data which can be executed by the micro processor 40, and address bus/data bus 20 connecting the micro processor 40 to the memory 10. The bit order of the terminal of the data bus 20 of the micro processor 40 and the bit order of the terminal of the data bus 20 of the memory 10 are changed.
