PURPOSE:To provide assistance in investigating the cause of deterioration in the performance of a specific routine by providing a storage part which records a routine consumed time and bus address information in an address indicated by address information from an address generation part. CONSTITUTION:A bus cycle comparison part 12 compares the bus cycle information with routine start/end comparison information and outputs a routine start/ end signal when they match each other. The routine start/end signal is inputted to a RAM address generation part 14, which generates a RAM address increasing when the signal becomes active. Further, a difference calculation part 15 inputs the routine start/end signal and calculates the routine consumed time. In a RAM 16, the routine consumed time outputted from the difference calculation part 15 and the bus address information supplied from a CPU 21 at this time are recorded as data by specifying the RAM address supplied from the RAM address generation part 14. |
