PURPOSE:To facilitate an easy detection for occurrence of a loop in debug and to quickly find out the cause of a fault, by attaining the loop state when the number of times accesses arranged to a loop deciding point provided at an optional point of a process program, reaches a prescribed level. CONSTITUTION:A breaking point BP is provided at an optional area of a program RPRO to be debugged. When the program TPRO reaches the point BP, the state inside a processor that is executed by the program TPRO is stored in a storage device or displayed at a display device DISP. In this case, a loop deciding point LP is set at an optional area of the program, and the number of times of accesses that is given to addresses ID0-IDn of each LP by a CPU is detected at a tracer part TRC. Then the executing frequency of each LP is counted by a loop counter CTR, and a loop state is realized when the counting of the counter CTR reaches a prescribed value. |
