Abstract

PURPOSE:To simply deal with the change of the number of file data or the change of the file size just with correction of the file name data by producing automatically the control information and the size information on all file data which are written into a ROM in accordance with retrieval of the file data. CONSTITUTION:Each file data to be written into a PROM 4 is retrieved out of a storage 8 by a control information production means 5 based on a file name at input of the file name data. Then the means 5 produces the control information in response to each file data. A size information production means 5 produces the information on the size of a storage area set in the PROM 4. Then the file data are successively transferred to a writing device 2 after both the control information and the size information on all file data to be written into the PROM 4 are transferred to the device 2. Thus it is possible to easily deal with the change of the chamber of file data or the change of the file size.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention processes file data into a format that can be read in the same format as that read from a disk and transfers it to a writing device, so that data can be written by a user. Possible read-only memory (Progra+nmableRead 0n
The present invention relates to a data processing device that allows data to be written to a memory (hereinafter also abbreviated as PR or OM).

Conventional technology Conventionally, file data is processed into a format that can be read in the same format as that read from a disk, and transferred to a writing device (hereinafter also referred to as a PROM writer).
A data processing device that allows data to be written to M is well known.

In conventional examples of such data processing devices, management information that should be added to file data in order to make it readable in the same format as read from the file is not created within the device.
Management information created in advance by an operator is read into the device and then transferred to the PROM writer.

Similarly, regarding the information regarding the size of the storage area to be set in the PROM according to each file data, the size information created in advance by the operator is read into the device together with the above management information, and this information is transferred to the PROM writer. After this information was written in the first storage area of the ROM, each file data was transferred to the PROM writer.

Problems to be Solved by the Invention However, it is difficult to read management information and size information created in advance as in the conventional data processing device described above.
There is a problem in that when the number of file data to be written to the PROM or the size of each file data changes, the management information and size information must be re-created each time.

Therefore, an object of the present invention is to create a simple file that lists the file names of file data to be written, without having to recreate management information or size information even if the number of file data or the size of file data changes. It is an object of the present invention to provide a data processing device that can easily handle the data by reading the data separately.

Means for Solving the Problems The present invention includes a disk-type storage device that stores input file data, and makes it possible to read the file data stored in the storage device in the same format as read from the file. In a data processing device, the data is processed into data in a format with management information added thereto, transferred to a writing device, and written to a read-only memory in which data can only be written by a user. When file name data listing the file names of file data to be written is input, each file data to be written to the read-only memory is searched from the storage device based on the file name, and management corresponding to each file data is performed. A management information creation means for creating information, and a size information creation stage f for creating information regarding the size of the storage area to be set in the write-only memory according to each file data based on the file data search, and read. This data processing device is characterized in that after the management information and size information created for all file data to be written in a dedicated memory are transferred to the writing device, each file data is sequentially transferred to the writing device.

According to the present invention, the management information and size information regarding all the file data to be written to the read-only memory are acquired along with the file data search within the take processing device based on the read file name data. Since it is automatically created, there is no need to re-create management information and size information in response to changes in the number or size of file data.

Embodiment FIG. 1 is a block diagram schematically showing a t/4 configuration of a data processing apparatus which is an embodiment of the present invention.

This data processing device includes a computer 1 and a PROM 4.
A communication line 3 connects the PR'○M-like 2 which writes data to the PR'○M-like 2.

The computer 1 has a central processing unit (Central'r).
occessiB Unit (hereinafter abbreviated as CPU), an input device 6, a display device 7, and a disk-type external storage device for temporarily storing file data input from the input device 6 and to be written to the PROM 4. It has 8 built-in.

In this data processing device, as a premise for transferring file data to be written to PROM 4 to PROM writer 2,
File name data as shown in Figure 2 is stored on the computer 1.
is created using the input device 6 and stored in the external storage device 8. The above file name data is a list of file names of each file data to be written into the PROM 4.

FIG. 3 is a flowchart I showing the procedure of data processing performed in the data processing apparatus.

Next, the procedure of file data processing by the data processing apparatus will be explained with reference to the flowchart of FIG.

First, in step n1, the file name data shown in FIG. 2 is read from the external storage device 8.

Prior to this, a plurality of file data are stored in the disk type external storage device 8 in the computer 1.

Based on the read file name data, the next step r
File data to be stored in PR○M4 is searched from among the file data stored in the disk-type external storage device 8. If the desired file data is found as a result of the search, proceed to step r+3.
In 77 file data search, information about the size of the searched file data is read based on the file data stored as an index together with the file data in the disk type external storage device 8. step n2
If the target file data cannot be retrieved, the process returns to Star 1 to point 1 and waits for the operator's decision.

In step n4, based on the information printed in step n3, read the management information corresponding to the retrieved file data, that is, the file data written to F ROM 4 in the same format as data read from the file. Management information to be written to the PROM 4 is created in order to ensure that the information is correct. In this case, creation of management information specifically means P.
R,0M4f file data storage area and its file 7
・There is no need to create an allocation map with a one-to-one correspondence between the index of the file data and the index. Therefore, not only management information for data retrieval in PROM 4 is created, but also storage area size information corresponding to each file data to be integrated into PROM 4 is created. Creation of this management information is done in the previous step r.
+ 2 to the next step n5t is repeated for all file data to be written to PROM 4 in sequence.

The management information created in this way is used in the next step n.
6, the data is temporarily stored in an empty area of the disk-type external storage device 6 in the combination 1-1.

Next, PR of the management information of the file data created earlier
The transfer to the OM writer 2 and the subsequent transfer of each file data to the PRORη writer 2 are carried out in step D7.

When one transfer of data to the PR, 0M writer 2 is completed, the data transfer is temporarily stopped at the next step n8. At this point, if there is still data to be transferred, wait for instructions from the operator, and when the operator gives an instruction to start transfer, the P ROM is transferred in the next step E]9.
Recognition information is transferred.

In this case, the P ROM recognition information refers to the P ROM 4 in which file data is written, or when it is installed in another data reading device.
There is information to let you know that the OM4 is installed, and it is written to the PROM4 at the same time as the file data is written. In this case, the PROM recognition information may be specially created within the computer 1, but the
It is also possible to use a data error check code added to each chip of the ROM 4 when writing data. Also, the size of the PR, OM recognition information is sufficient to be several bytes, or if the efficiency when accessing the PR, OM 4 is achieved, the sector rank = J, f
S is preferably an allocation map.

After the transfer of the PR, OM recognition information, the remaining file data is transferred in the next step E]10.

Next, it is checked in step r]1]-4 step 1) whether or not the data transfer for each PROM 4 unit has been completed. will be held.

P R, (:) M When the data transfer of 4 units is completed, it is checked in the next step n12 whether or not there is any remaining data to be transferred, and if there is, the process is further performed in step n7. The remaining data is written to another PROM 4 by repeating the execution of nl,2.

In this way, all the file data is transferred to the PR○M writer 2, and the transferred file data is written to the PR,OM 4 along with double management information and PROM recognition information. .

In this case, as mentioned above, there is a transfer of PROM recognition information during the transfer of file data, but the discontinuity of file data in PROM 4 due to this is prevented by the PROM writer 2 hetator by the program implementing the present invention. Automatically supplemented during transfer.

Furthermore, the number of times the PROM recognition information is written in the PROM 4 is basically the same as the number of times that the PROM recognition information is written in the PROM 4, even if one piece of ROM recognition information is written in one ROM, as another embodiment of the present invention.
Since the size increases or decreases depending on the storage capacity of the PROM 4, the PROM recognition information can be used instead of the size information without specifically writing size information indicating the storage capacity in the PROM 4.

According to the data processing apparatus of the present invention, management information and size information regarding all file data to be written to the read-only memory are processed based on the read file name data. Since it is automatically created when file data is searched within the device, management information,
There is no need to recreate the size information, and it can be easily handled without modifying the file name data.
