PURPOSE:To grasp the execution condition of a program accurately by displaying numerically the execution start time, execution end time, and execution time of each task of the program which operates on real-time basis. CONSTITUTION:A means of displaying numerically the execution start time, execution end time, and execution time of each task of the program which operates on real-time basis is provided. For example, a program counter 1 is stored with the address of the program being executed, and a start address setting circuit 2 and an end address setting circuit 3 are stored with a start and an end address. Then, a start address comparing circuit 6 and an end address comparing circuit 7 compare the contents of the program counter 1 with pieces of address information in the address setting circuits 2 and 3, and when coincidence is obtained, the value of a timer 5 is given to the start time setting circuits 8a-8g or end time setting circuits 9a-9g for the execution task specified by a task setting circuit 4. |
