Abstract

PURPOSE:To improve the debug processing efficiency of a program by providing a reference register saving means to which the contents of the register are saved after the execution of the program to be debugged. CONSTITUTION:The contents of a register are stored into an initial value setting register saving means 3a before the execution of a program to be debugged. While the contents of the register are stored into a reference register saving means 3b after the execution of said program. Then an exclusive OR, for example, is secured between both registers 3a and 3b and saved in a register non- coincidence information storing means 5. Thus it is possible to retrieve the bit positions of the changed register contents by reference to the means 5. As a result, the register contents can be confirmed before and after the execution of the program to be debugged. Furthermore the bit positions can also be confirmed when the register contents have changes. In such a way, the time needed for the program debugging jobs can be shortened and the debugging processing efficiency is improved.
