2. Description of the Related Art Conventionally, as a performance measurement system of this type, as shown in FIG. 7, a data processing device (particularly a device having a firmware mechanism) 5 includes a timer 51 for controlling sampling timing and a timer 51. A performance measurement control unit 52 that performs overall execution control for measuring the performance of a program in response to an interrupt; sampling period information 53a and performance measurement item information 5 that perform performance measurement;
Measurement control table 53 for managing measurement control information such as 3b
And a performance measurement unit 54 composed of firmware having a performance of collecting performance measurement data according to the performance measurement item information 53b of the measurement control table 53, and a log area 55 for storing the collected performance measurement data. is there. This system is disclosed in JP-A-1-1457.
No. 36 discloses this.

In the data processing device 5, a program 56
When the performance measurement is performed, the performance measurement control unit 52 starts or ends the sampling period of the sampling period information 53a of the measurement control table 3 if there is an interrupt from the timer 1 that controls the sampling timing during the execution of the program 56. Is determined by the determination unit 52a.

When the determination section 52a of the performance measurement control section 52 determines that the sampling period has started, the performance measurement start control section 52b executes one instruction when each instruction of the program 56 is executed in the setting state of the performance measurement environment 57. Every time the execution of the instruction is completed, a hardware interrupt is issued to the performance measuring unit 54.

[0005] The performance measuring unit 54 analyzes the hardware interrupt, and according to the performance measuring items designated by the performance measuring function of the firmware, the simulation unit 5 performs the following.
At 4a, a simulation of instruction execution is performed, etc., and predetermined performance measurement data is collected at the data collection unit 54b, and stored in the log area 55. Thereafter, control is returned to the program 56 to execute the next instruction.

When the determination section 52a of the performance measurement control section 52 determines that the sampling period has ended, the performance measurement end control section 52c releases the performance measurement environment 57 for the program 56. As a result, the program 56 executes instructions under a normal execution environment until the next performance measurement environment 57 is set.

In the above performance measurement system, the performance evaluation information to be collected when executing the firmware program is diversified without using a dedicated circuit by hardware, and the collection items can be set arbitrarily, so that the dynamic state can be controlled.
