本発明は所要時間測定方式に関し、特に電子計算機によ
るデータ処理における特定区間の所要時間の測定に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for measuring required time, and particularly to measuring the time required for a specific section in data processing by an electronic computer.
従来、この種の時間測定に関しては、システムが内蔵し
ている時刻装置やインターバルタイマを使用する方式や
、高精度の外部測定装置を使用する方式等の２種類の方
式があった。Conventionally, there have been two types of methods for this type of time measurement, such as a method that uses a time device or interval timer built into the system, and a method that uses a high-precision external measuring device.
上述した従来の所要時間測定方式においては、内蔵装置

ずその測定装置を設置する必要があり、測定時期や測定
場所が限定される等の問題点があった。In the conventional time measurement methods described above, methods that use built-in devices have low accuracy in measuring time, and methods that use high-precision external measuring devices require that the measuring device be installed at the time of measurement. However, there were problems such as limitations on the timing and location of measurements.

有メモリ上の制御指示子とを有している。The required time measurement method of the present invention is applicable to a multiprocessor system that shares memory, in which a processor under test executes a program under test that includes a specific section in which the required time is to be measured, and a and a control indicator on a shared memory for notifying the measurement program of the start and end of a specific section of the program under test.
次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

２）を終了すると、制御指示子４に終了値を格納する。In FIGS. 2 and 3, in this embodiment, the program under test 2 stores a start value in the control indicator 4 at the start of a specific section (processing 1). As a result, the measurement program 6 repeats the process of adding 1 to the repetition counter 4 as shown in FIG. When the program under test 2 finishes the specific section (processing 2), it stores the end value in the control indicator 4.
これにより測定プログラム６は繰返しカウンタ７への加
算を中止する。この時、繰返しカウンタ７に格納されて
いる値が特定区間（処理２）の所要時間である。As a result, the measurement program 6 stops adding to the repetition counter 7. At this time, the value stored in the repetition counter 7 is the required time for the specific section (processing 2).
測定プログラム６内の測定時の繰返しを構成している処
理（第３図ａ、ｂ間の処理〉は非常に少ない命令（数命
令程度）で構成されており、所要時間の精度は数命令の
処理時間程度となる。The processing that constitutes the repetition during measurement in the measurement program 6 (the processing between a and b in Figure 3) consists of very few instructions (about a few instructions), and the accuracy of the required time is as low as a few instructions. It will take about processing time.

る。As described above, one embodiment of the present invention has a processor under test having a program under test, a measurement program measurement processor, and a control indicator on a shared memory, and the program under test specifies a specific interval in the control indicator. Provides a required time measurement method in which the number of repetitions of a specific process within a measurement program from storing a start value indicating the start to storing an end value indicating the end of a specific section is the time required for that specific section. do.

。As explained above, in the present invention, after the program under test stores a start value indicating the start of a specific section in a control indicator,
By setting the number of repetitions of a specific process in the measurement program until the end value indicating the end of the specific section is stored as the required time for that specific section, the required time can be obtained with relatively high accuracy. Furthermore, since no external measuring device is required, there is an effect that there are no limitations on the timing or location of measurement.
