Abstract

PURPOSE:To store the ROM data or programs with reduction of the storing space by using a data register processing means which registers the data into a floppy disk together with file names in a prescribed structure of data and takes the data of a specific file name out of the floppy disk for output of this data. CONSTITUTION:A 1st operation is carried out, that is, a mode key, a 1-key and a set key, for example, are successively pushed and then the set key is pushed again after inputting a file name. Thus the storage contents of a ROM is putted to a ROM writer are supplied from a terminal 1 and the file name is registered into a floppy disk via a floppy disk memory 5. In the same way, the data on the floppy disk are written into the ROM put into the ROM writer. In such a way, a large quantity of ROM data can be stored safely with reduction of the storing space with no back-up received from another computer system.

Description

Detailed Description of the Invention -1-' (Industrial Application Field) This invention provides ROM data or programs that are necessary for normal operation of electronic equipment equipped with a microprocessor, etc. It relates to ROM data storage devices for storage.

(Prior Art) Conventionally, in order for electronic devices equipped with microprocessors and the like to operate at relatively high speeds, the necessary data or programs have been stored in a form that operates at high speed and cannot be erased when the power is turned off, that is, ROM. (Read 0nly Mem
For example, a P-ROM in which the data is written is installed in the electronic device, and the electronic device is operated. When it is necessary to change or revise the operation of the device operated as described above, the P-ROM is generally replaced with a P-ROM in which new data has been written. A ROM writer was used to create the data. In other words, by manually inputting data or programs via a ROM-like human key,
M is created, this master ROM is used for storage, and the data of this master ROM is transferred to the RAM of the ROM writer at any time.
A ROM necessary for the operation of the electronic device was created by transferring data from this RAM area to a P-ROM to be installed in the electronic device and being replaced, and then burning and writing the data.

(Problem to be Solved by the Invention) However, in the case of data or programs stored in the master ROM as described above, the data or program is stored in the physical form of the master ROM, that is, in a dual inline package. When the number of ROMs increases, there is a problem that a considerable amount of storage space is required, and there is a risk of damaging the master ROM, making management cumbersome.

In order to solve the above problems, the present invention provides a ROM data storage device that stores and manages ROM data or programs in a space-saving manner.

(Means for Solving the Problems) The ROM data storage device of the present invention includes input/output data converting means for converting serial data into parallel data and converting parallel data into serial data, and a file name for assigning a file name to the data. data registration processing means for registering data with a predetermined data structure on a floppy disk, and extracting and outputting data with a specific file name from the floppy disk; and human power means such as processing instructions for inputting file names, etc. to the data registration processing means. The present invention is characterized in that it includes a liquid crystal display means for displaying matters related to the data registration processing means, and a floppy disk storage device for storing the output of the data registration processing means.

(Function) In order to write data or programs necessary for the operation of an electronic device equipped with a microprocessor or the like into a ROM, the data is first stored in a floppy disk, and then the data is read out and written into the ROM.

That is, a ROM writer manually writes data or programs into its memory through its keys and display. This data is then taken in by the ROM data storage device of the present invention via the R8-232G signal line. Next, this received data is stored or stored on a floppy disk. R
To write data to the OM, the data stored on the floppy disk as described above is transferred to the R5-232.
Sends it to the ROM writer via the C signal line and stores it in its RAM.
The memory contents are stored in the ROM using the ROM writer function.

(Embodiment) Next, an embodiment of the ROM data storage device of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a ROM data storage device of the present invention, and FIG. 2 is a flowchart showing an operation algorithm of an example of the ROM data storage device of the invention.

In Figure 1, I is the RR5-232CI child,
This is R3-232G of ROM writer or programmer etc.
Connected via a terminal and its signal line or cable. R
The data or program of the OM writer is input via the R3-232C terminal 1 or output thereto. 2 is input/output data conversion means, and the R5-232G terminal I
Converts manually input serial signals to parallel signals.

Further, for example, a parallel signal outputted from the I10 port described later is converted into a serial signal and outputted to the R3 to 232C terminals I. Reference numeral 3 denotes a processing command input means, which is specifically formed to include, for example, a key matrix, from which various processing commands to be described later and, for example, file names for the data registration processing means to be described later, are input manually. Reference numeral 4 denotes a liquid crystal display means for displaying necessary items related to the input means 3, such as the processing commands. Reference numeral 5 denotes a floppy disk device, which is, for example, a 3.5-inch floppy disk drive, and is used with a 3.5-inch floppy disk loaded therein. 6 is a microprocessor, for example, an 8-bit microprocessor, which processes the above-mentioned means and I.
10 are connected via port 7. Reference numeral 8 denotes a ROM area of the ROM/data storage device of the present invention, in which, for example, a program for executing the algorithm shown in FIG. 2 is loaded. Reference numeral 9 denotes a RAM area, which is a memory for working purposes, etc.

The data registration processing means is mainly formed of the microprocessor 6 and a program that executes the algorithm shown in the flowchart of FIG. The file name inputted from means 3 is given and registered on the floppy disk in a predetermined data structure. Further, when a specific file name is entered manually from the processing command etc. input means 3, the data of that file name is read from the floppy disk.

Next, to explain the operation of the ROM data storage device of the present invention, as shown in FIG. When a key is pressed, the stored contents of the ROM inserted into the ROM writer are input from the R5-232C terminal 1, and are registered in the floppy disk by the floppy disk storage device 5 with the file name. When the second operation is executed in the same way, the data on the floppy disk is written to the inserted ROM in a ROM-like manner. Thereafter, each operation is similarly executed, for example, in the third and tenth operations shown in FIG.

(Effects of the Invention) The ROM data storage device of the present invention includes an input/output data conversion means for converting serial data into parallel data and vice versa, and a floppy disk with a file name attached to the data and a predetermined data structure. a data registration processing means for registering data with a specific file name from a floppy disk and outputting it; a processing command input means for inputting a file name, etc. to the data registration processing means; and a data registration processing means related to the data registration processing means. An industry in which the output of the data registration processing means and the liquid crystal display means for displaying information to be stored can be stored safely in a space-saving manner without the support of a data system, and the stored data can be retrieved or read out quickly. It has a remarkable effect.
