<p>PURPOSE:To change the measuring point of the execution time of a program without changing the program. CONSTITUTION:The program is executed repeatedly at every definite period time TS, and the count data 31 of a timer 30 is reset before the execution of the program. When addresses A1 to A4 set in debug registers 11 to 14 are intended to execute during the execution of the program, the processor 10 generates debug interruption. Then, it reads the count data 30 of the timer 30 and stores it in a memory 20 as the execution time T1 to T4. A monitoring device 2 reads the execution time T1 to T4 out of the memory 20, and displays it on a display screen.</p> |
