Abstract
PURPOSE:To easily perform the debugging of a program, by holding not only the address of a jump destination but that of a jump instruction at the time of executing the jump instruction. CONSTITUTION:The address of the jump destination is stored in a next program counter 1 by the jump instruction. When the jump destination is not program area and an operation code is undefined, interruption is generated in a control unit 7, and an interruption operation is executed. In such a case, an address indicating the jump destination is stored in a current program counter 2, and the address of the jump instruction is stored in a previous program counter 3. In such a way, it is possible to refer to the previous program counter 3 in performing the interruption processing, and to inform the address to be debugged accurately to a user.
