のデータ伝送方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data transmission method for transmitting data in a front end section of an information processing network connecting a plurality of information processing devices.

処理データとが混在している。Conventionally, this type of data transmission method uses FIFO when exchanging data between information processing devices, regardless of the content of the data.
The transmission was taking place. On the other hand, if we focus on the nature of the data, there are two types of data: immediate processing data with a strong real-time nature, such as alarm notifications or CRT screen display signals, which are related to man-machine interfaces, and logging data, which do not need to be processed in real-time. There is a mixture of delay processing data that is good, that is, delay processing data that can be processed with delay.

ヘッドが増加するという欠点があった。In the conventional data transmission method described above, transmission processing is performed in the order of arrival regardless of the nature of the data, so data that can be processed immediately and data that can be processed with a delay are sent at random during times of high school and high school. However, as a result, the transmission processing of immediately processed data is delayed, and the overhead associated with data transmission increases.

段を片んで構成される。Means for Solving the Problem] The data transmission system of the present invention includes a data processing means for generating data, and a data discrimination method for receiving data from the data processing means and discriminating whether the data is immediately transmitted data or delayed transmitted data. means, data storage means for temporarily storing the delayed transmission data from the data discrimination means, and transmission for transmitting the immediate transmission data received directly from the data discrimination means and the delayed transmission data received from the data storage means. means, overflow detection means for transmitting the data in the data storage means to the transmission means when the data storage means overflows; and overflow detection means for transmitting the data in the data storage means to the transmission means; The overflow detecting means is configured to transmit the data of the data accumulating means to the transmitting means when a predetermined time has elapsed after the data is received by the data accumulating means.
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.

In general, the data from each of the processing units (each consisting of a large number of processing units) is discriminated by the data discrimination circuit 3 as whether it is immediate processing data or delayed processing data.If it is immediate processing data, it is immediately sent to the transmitting circuit 5, and if it is delayed processing data, it is sent to the transmission circuit 5. data buffer 4
At the same time, the timer 6 is started. The size of the data buffer 4 is equal to the maximum length of the transmission record, and the number of data items that can be stored is the value obtained by dividing the transmission record length by the data length.

。When the frequency of occurrence of delayed processing data in the data processing section 2 increases, the data buffer 4 sequentially stores data, and when it becomes full, the overflow detection circuit 7 outputs an overflow notification to the data discrimination circuit 3. Upon receiving this overflow notification, the data discrimination circuit 3 outputs a transmission request to the transmission circuit 5 to transmit the contents of the data buffer 4. The data discrimination circuit 3 outputs a transmission request for transmitting the contents of the data buffer 4 to the transmission circuit 5, and at the same time resets the timer 6. The transmission circuit 5 performs batch transmission of the contents of the data buffer 4 as one transmission record.

効果がある。As described above, the present invention distinguishes between immediate processing data and delayed processing data depending on the content of the data, and transmits immediate processing data without any time delay while storing delayed processing data in the data storage means. Batch transmission increases the number of data items that can be transmitted in one transmission timing, reduces overhead, and increases data transmission efficiency without multiple processes.
This has the effect of increasing the transmission time allocation for the axiomatic processing data.
