1 will be described as an example. The data processing device 41 is initialized when the power is turned on, and thereafter the algorithm data reading means 4111 reads the algorithm data from the algorithm file 211 in the external storage device 21,
This is transferred to the storage unit 413. Also, the receiving means 411
2 is waiting for an instruction from the host device 1. Host device 1
Transmits a data processing instruction to the processing target data group 212 in the external storage device 21 to the data processing device 41 via the processing instruction path 31. The data processing instruction is received by the receiving unit 4112 of the control unit 411 and transmitted to the data processing control unit 4113. Data processing control means 4
The 113 controls each means as follows in accordance with the data processing instruction. First, the algorithm data stored in the storage unit 413 is extracted and transferred to the processing unit 412. Then, the processing target data reading unit 4114 reads the processing target data from the processing target data group 212 in the external storage device 21 and transfers it to the processing unit 412.
Upon receiving the algorithm data and the processing target data, the processing unit 412 selects the algorithm designated by the algorithm data from the prepared algorithms and processes the processing target data according to this algorithm. The processing result reading unit 4116 reads the processing result after the processing in the processing unit 412 is completed. Then, the processing result is temporarily stored in the processing result reading means 4116, converted into a predetermined format, and then transmitted to the transmission means 4.
It is transmitted to the higher-level device 1 via 115. After that, the receiving means 4112 waits for an instruction from the host means 1. After receiving the processing result from the data processing device 41, if there is another data to be processed, the higher-level device 1 instructs the data processing device 41 to perform data processing in the same manner as the above processing.

Next, the algorithm data reading means 4
The detailed operation of 111 will be described with reference to the flowchart of FIG. First, the operation of the algorithm data reading unit 4111 is started by the initialization when the power is turned on.
First, the algorithm data loaded flag in the algorithm data reading means 4111 is reset (17
001), the algorithm data is read from the algorithm file 211 in the external storage device 21 (1700
2) and stores it in the storage unit 413 (17003). After that, the algorithm data loaded flag is set, and the process ends. Also, when the receiving unit 4112 receives the algorithm data load instruction from the higher-level device 1 and thus activates the algorithm data reading unit 4111, the same processing is performed.

Next, the detailed operation of the receiving means 4112 will be described with reference to the flowchart of FIG. First, the operation of the receiving means 4112 is started by the initialization by turning on the power source, and the waiting state for receiving the instruction from the higher-level device 1 is set (18).
001). When the instruction is received, the instruction received flag in the receiving means 4112 is set (18002), and then the received instruction is checked (18003). If the received instruction is an algorithm data load instruction, the algorithm data reading means 4111 is activated (18005), the instruction reception completion flag is reset (18009), and the instruction reception standby is entered (18001).
On the other hand, if the received instruction is a data processing instruction, it is checked whether or not the algorithm data loaded flag in the algorithm data reading means 4111 is set (18004). If it is not loaded, the algorithm data reading means 4111 is checked. After starting (180
07), and activates the data processing control means 4113 (18008). If the algorithm data has been loaded, the data processing control means is immediately activated (18008). Then, the instruction reception completion flag is reset (18009), and the instruction reception waiting state is set to wait for the next instruction (18001).

Next, regarding the detailed operation of the data processing control means 4113 activated by the reception means 4112,
This will be described with reference to the flowchart of FIG. When the data processing control unit 4113 is activated by the reception unit 4112, first, the algorithm data is read from the storage unit 413 and transferred to the processing unit 412 (1900).
1). Then, the processing target data reading unit 4114 is activated to send all the processing target data instructed by the higher-level device 1 to the processing unit 412 (19002). Then, after the data processing in the processing unit 412 is completed, the processing result reading means is activated to read the data processing result (19003).

Although the data processing device 41 has been described as an example here, in the other data processing devices 42 to 44 as well, the algorithm data is centrally stored in the algorithm file 211 of the external storage device 21, and the higher order. The device 1 delivers to each data processing device. However, since the data to be processed is different in each data processing device, it is distributed and stored in each external storage device.

As described above, in the fifth invention of the present application, in addition to the second invention of the present application, the algorithm data is resident only in one external storage device 21 in the system, and the algorithm data is stored in each The algorithm files are read by the algorithm data reading means of the data processing device and stored in the storage unit of each data processing device, so that the algorithm files are duplicated in all the external storage devices in the system as compared with the second invention. Therefore, it is not necessary to hold the data and the algorithm data is not read from the external storage devices 21 to 24 as compared with the fourth aspect of the present invention, so that the process can be performed at high speed.

[0052]

As described above, according to the present invention, the algorithm file for storing the algorithm data is made resident in the external storage device so that the file can be created every time the host device gives a data processing instruction. It can be omitted. Further, since it is not necessary to newly create a file each time, it is not necessary to duplicately hold data having similar contents, and the external storage device can be efficiently used. Further, by providing a dedicated storage unit in each data processing device to store the algorithm data in advance, the operation of reading the algorithm data from the external storage device at the time of processing can be omitted.
