PROBLEM TO BE SOLVED: To easily obtain a source code suitable for a new CPU even when there is no replacement instruction for an assembly language of a changed CPU in creation of the source code of the CPU after alteration from an assembly language source code of the CPU before the alternation in replacement of a CPU in a microcomputer or even when replacement is carried out to a CPU having a less number of registers from that with a larger number of registers. SOLUTION: The assembly language 2 source code 15 is not created directly from an assembly language 1 source code 11, but a C language or C ++ language source code 13 is created once by a decompiler 12. When the created C language or C ++ language source code 13 is compiled by a compiler 14 of the CPU 2 to be changed, an assembly language 2 source code 15 suitable for the new CPU 2 can be easily obtained early.
