In recent years, with the development of information processing equipment, especially personal computers, data processing systems have been developed that utilize these devices to centrally control various manufacturing equipment, or to connect multiple control devices for central management control. has been done.

For example, a data processing system that centrally manages and controls LSI process steps, etc. consists of a main data processing device that centrally manages manufacturing data, etc. related to one process, and a data processing system for manufacturing equipment based on the manufacturing data, etc. It consists of multiple sub-data processing units.

According to this, when there is a change in the data centrally managed by the main data processing device, the changed part of the data is transferred to each sub data processing device, or conversely, the data is changed when starting each sub data processing device. All data including parts were received.

For this reason, systems connected via communication lines require complicated software to manage data in the secondary data processing equipment, and it takes a lot of time to transfer the latest data for revision processing. There is a problem.

Also, in systems that are not connected via communication lines,
There is a problem in that revised data and the like must be supplied via a floppy disk, resulting in a decrease in functionality and speed of a data processing system that is centrally managed and controlled.

Therefore, when there is a change in the data centrally managed by the main data processing device, a device and method are proposed that can perform revision processing in a short time based on the changed data by performing the minimum data exchange processing. desired.

It consists of an n-th sub-data processing device 4 that processes data of other devices based on other data Dc.

The purpose of this system is to easily and quickly grasp the status of a series of processes, such as LSI manufacturing processing, testing processing, and production volume, by centrally managing LSI processing processes, etc. .

This makes it possible to improve LSI production management.

In addition, in this system, for example, when a change occurs in the manufacturing data Da, test data Db, and other data Dc due to the development of a new LSI, etc., each of the sub data processing devices 2 to 4 has a method for changing the data. Existing data Da,
It is necessary to perform revision processing for Db and Dc.

The revision process at this time is a system in which the main data processing device 1 and each of the sub data processing devices 2 to 4 are connected via a data bus 8, etc., and a method in which only the data of the changed part (hereinafter referred to as revised data) is rewritten. According to , this is performed by selecting the sub data processing devices 2 to 4 that correspond to the revised data and transferring the latest data related to the sub data processing devices 2 to 4 to the sub data processing devices 2 to 4. Moreover, according to the method of rewriting all data, when each of the sub data processing devices 2 to 4 starts data processing, it is possible to receive the latest data including the changed part stored in the main data processing device 1. It is carried out by

In either case, the main data processing device 1 performs data management processing that constantly monitors the presence or absence of revision processing in each of the sub data processing devices 2 to 4 and whether or not the latest data necessary for the revision processing has been transferred.

In addition, the main data processing device 1 and each of the sub data processing devices 2 to 4

When starting up the secondary data processing device, all data including changed portions are transferred.

For this reason, systems connected via communication lines require complicated software to manage data in the secondary data processing equipment, and it takes a lot of time to transfer the latest data for revision processing. Sometimes. For example, according to the former method, a main data processing device manages all connection states of multiple sub data processing devices connected to a communication line, and determines the transfer destination and whether old and new data has been transferred. Requires complex data management to understand.

Furthermore, according to the latter method, even if there is a large number of data items to be managed and the revised data involves revising a portion of the data in each sub-data processing device, all of the data will be transferred and processed. Therefore, a long time is required for the transfer. In addition, in systems that are not connected via a communication line, revised data etc. can be sent via a floppy disk.
+ Due to the indispensable kneading, there is a problem that the functionality of the data processing system that centrally manages the LSI process steps etc. deteriorates and information transmission lacks speed.

Next, the data processing method according to the first implementation side of the present invention will be explained while supplementing the operation of the device.

FIG. 5 shows a flowchart of the revision process of the main data processing system according to the first embodiment of the present invention.

For example, data D1 having a sequential file data structure that is centrally managed by the main data processing system M as shown in FIG.
, D2. Based on Di, Dn, one or more sub data processing systems S1. S2. In the case where the data processing systems Si and Sn perform data processing, the data revision processing of the sub data processing systems S1, S2, Si, and Sn based on the data change of the main data processing system M is performed by the sub data processing systems S1, S2. From Si and Sn to the main data processing system M, data D1. D2. This is performed based on the inquiry process of version number data H1, H2, and Hi assigned to Di and Dn.

That is, in FIG. 5, first, in step P1, the latest data D1 is inputted. At this time, the data Di, D are sent from the data storage section 24 through the data input/output section 26B.
2. Di and Dn are read and transferred to the pig display section 21B and the data storage section 25. Here, the read data is assumed to be old data. Further, the latest data Di is input using the keyboard 21A. The old data and the latest data Di are displayed on the data display section 21B.

Next, in step P2, a comparison process between new and old data is performed based on the input process. At this time, the version number assignment processing section 22 compares the old data temporarily stored in the data storage section 25 with the latest data D1 inputted using the keyboard 21A.

Thereafter, in step P3, it is determined whether or not the data has changed. Here, if the data has changed (YES)
, move to step P4, and if it does not change (
If NO), the revision process ends.

Therefore, when performing revision processing, version number counting and amplification processing is performed in step P4. At this time, the version number assignment processing unit 22 takes out the version number data Hi, and, for example, the version number 1 is incremented by one count (↓1) to become the version number 2. As a result, the latest data D1 is given the version number 2, which serves as a code to distinguish between the new and the old data.

Next, in step P5, new and old version number data H1, H2, H
Performs storage processing for i. Here, the data input/output unit 26B transfers the old and new version number data H1, H2Hi to the data storage unit 2.
5 and is transferred to the version number data storage section 23. At the same time, the latest data D1 is stored in step P6. At this time, similarly to step P5, the latest data D1 is transferred from the data storage section 25 to the data storage section 24 by the data input/output section 26B.

Thereafter, in step P7, a process for selecting a standby process/simultaneous notification process mode is performed. At this time, in the case of the standby processing mode W, the process moves to Step P8, and in the case of the simultaneous notification processing mode A, the process moves to Step P9.

Therefore, in the case of standby processing mode W, standby processing related to inquiry processing from the sub data processing systems 51 to Sn is performed in step P8. At this time, the system control unit 26C temporarily stores the latest version number data and the latest data related to the revision process in the data storage unit 25, and the king data processing system M shifts to other data processing.

In addition, in the case of simultaneous notification processing mode A, step 7 P9
Then, a simultaneous notification process is performed to the sub data processing systems 81 to Sn. The simultaneous notification process at this time is because there is a data change in the main data processing system M, and revision processing occurs in the data managed by it, and revision processing is also required in each of the sub data processing systems Sl to Sn. This is the content of the announcement.

Thereafter, in step PIO, data transfer processing is performed based on the inquiry processing from the sub data processing systems 31 to Sn. At this time, the data communication processing unit 26A transfers the latest version number data H] and the latest data Di via the communication line 33 to the relevant sub data processing system S1 where the inquiry process was performed.

No. 60 shows a flowchart of revision processing of the sub data processing system according to the first embodiment of the present invention.

In the figure, first, in step P1, the version number management file of the main data processing system M is inquired. The inquiry process at this time is performed at any time or periodically.

Further, it is performed based on a simultaneous notification process from the main data processing system M. For example, the version number % [0 record of the main data processing system M file is queried and compared with the self-managed version management file. That is, 1.
