The communication system side (21) calculates the input time using the child clock η, calculates the transmission completion time of the packet, and calculates the processing time from the input time and the transmission completion time using the input time. It has become.

The invention was made in order to eliminate the drawbacks of the conventional ones as described above, and it is possible to calibrate the clock between processes, eliminate unnecessary overhead time opening from the transmission device, and calculate the internal processing time. It provides a packet transmission value # that can be set to be suitable for this purpose.

る。N21 An embodiment of the present invention will be explained based on FIG. 2, in which the same parts as in FIG. 1 are denoted by the same reference numerals. The pulse output device is designed to output a pulse when the communication control device completes sending a packet, and the internal processing time is calculated based on the time difference between these two pulses. The measurement is becoming unstable.

送値#を得ることができる。That is, in FIG. 2, when the processor (1) receives specific information, it first performs processing to output a pulse from the pulse output device 03, and then processes the information and outputs a packet. 1st communication flll111@
When the W position (21 inputs a packet and completes sending the packet to the transmission line), the pulse output device A performs the process of outputting the pulse. Therefore, the measurement of the processing time of the information 41!1 can be easily carried out by directly determining the time difference between these two pulses using an externally connected measuring instrument such as a synchroscope. The complicated process of checking each clock and calibrating the clock is a military document, but it is possible to obtain the packet transmission value # suitable for determining the internal processing time.

Of course, it can also be used to measure the distance between words processed up to the output of information.
