(57) Abstract On-chip trace cash in order to bring software efficiency profiling information (200) and the processor based device which installs the support circuit (102) is offered. The trigger control register (219a), it initializes the 1st on-chip counter the occasion where it enters to the procedure which is selected in order the trigger (start) to do, it is constituted. The 2nd trigger control register (219b) although the 1st counter is stopped the occasion where it enters into the procedure prolog of the procedure which is selected it is used. The count value which reflects the execution time when the procedure which is selected elapses there store is done in on-chip trace cash. Also the 2nd counter is provided. The 2nd counter operates continuing, but it is reset to zero after the stop trigger event which it occurs with the 2nd trigger control register. In addition, on-chip trace cash (200) you can insert inside value of the 2nd counter due to the stop trigger event. Although from value of this 2nd counter, frequency of occurrence of the procedure which is the object of interest is brought the 1st counter brings the information regarding the execution time of procedure. Although the profile data is analyzed, being executed vis-a-vis the target system the after-treatment software, making use of either host system or ohuchitsuputoresukiyapuchiyahadouea which utilizes the debugging port it is good.
