Abstract

PURPOSE:To improve the operability of data correction by a simple constitution by storing inputted data, displaying the data together with data position information and processing and outputting the stored data. CONSTITUTION:In the case of editing binary data, the data are stored from a ROM writing device 6 into a data storing means 2 through a data input means 1 and displayed on a display means 4 from the head of the data at first. A cursor is set up to the head of the screen of the means 4 by an integrated control means 5 and then moved in the horizontal/vertical direction by an arrow key in an operating means 3 so as to be moved to the position of data to be changed. The data on the cursor are inputted by the means 3. The control means 5 replaces the data pointed out by the cursor on the means 4 by the inputted data and rewrites the display of the changing part on the means 4. The function of editing processing is transmitted to the means 5 by a control key on the means 3 and the means 5 outputs the editing processing and the request to the means 1, 2, 4.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a binary data editing device for editing data in any format used in fields such as converters.

2. Description of the Related Art Conventionally, as devices for editing data, there are those called line editors and screen editors that handle only character data, and those that can edit binary data such as debuggers.

The former handles only data in a certain area defined as characters in a system-dependent manner, and performs editing using a wealth of editing functions such as search, deletion, insertion, and replacement. The latter calls binary data such as programs and numerical data using position information, unique symbol information, etc., and processes the data.

Problems to be Solved by the Invention However, in the above conventional method, the program is
When writing to a computer, the program often needs to be modified and transferred many times. To modify the program during this process, it was necessary to either modify the source code and recompile each time, or to manipulate data on a debugger or ROM writer that was difficult to read and had poor editing capabilities. . In other words, with an editor that handles only character data, when editing data that includes data other than characters, the data cannot be displayed and editing operations cannot be performed. If you are still using a debugger, you cannot use editor functions such as specifying display addresses or searching. Therefore, to change the binary data, it was necessary to either change the NNU code and edit only the C character data as described above, or to perform processing using a debugger or the like.

Means for Solving the Problems The binary data editing device of the present invention replaces all numerical data with character data representing a numerical value in units of 1 byte, and if the data falls within the range of the character data and the position information of the data, Along with the characters, a certain amount of data is displayed on the screen in an orderly manner. A cursor representing the position of data that can currently be changed is placed on this screen, and the cursor is moved in response to a Kahnle movement signal from an input device such as a keyboard to move the data position to be changed.

It also provides functions such as searching, inserting, deleting, and replacing data using character strings and numerical values, allowing data to be edited freely.

Function: This configuration provides a practical data editing device that allows binary data editing work to be easily performed and allows the output timing and version to be freely selected.

EXAMPLES Hereinafter, examples of the present invention will be described using FIGS. 1 to 3.

FIG. 1 is an overall configuration diagram of an embodiment of the present invention.

In FIG. 1, data is input from the ROM writing device 6, external storage device 7, communication port ff58, etc. through the data input/output means 1, and is stored in the data storage means 2. After the data is stored in the data storage means 2, the general control means 6
displays a certain amount of data in the data storage means 2 on the display means 4.

After displaying on the display means 4, the general control means 6 waits for an operation or a data signal from the operation means 3, and upon receiving the operation signal, performs an editing operation on the data in the data storage means 2 according to the signal, and converts the data signal When received, the value of the data currently indicated by the cursor is changed and displayed on the display means 4 again. Similarly, various editing operations are performed, and the output control function causes the general control means 6 to output the data in the data storage means 2 at that time through the data input/output means 1 to the target output light.

FIG. 2 shows detailed display contents of the display means 4 in one embodiment of the present invention.

FIG. 2 specifically shows the process in which the data in the data storage means 2 is displayed on the display means 4. In this example, the data in the data storage means 2 is expressed in hexadecimal by the comprehensive control means 5. The character data is converted into ASCII characters O~9, &~f, and the start address of the line is displayed in hexadecimal on the left side of the data so that the position of each data can be known. Furthermore, binary data often contains character strings, and if the data is ASCII characters or Schiff) JIS kanji code, the characters are displayed on the screen cloth. The character display corresponds to the data in the - line in order (Oshi, non-ASCII and non-shift) JIS data is 1
．． (dot). A cursor indicating the position of data that can be currently changed by the comprehensive control means 6 is displayed on the data display section at the center of the screen.

FIG. 3 shows the operation means 3 that transmits operation signals and data signals to the comprehensive control means 6, and is composed of operation keys for executing operation functions, a numeric keypad for inputting data signals, and alphabet keys. has been done.

The details of the operation of the embodiment of the present invention will be described below.

When actually editing binary data such as data or programs on a ROM, data is stored in the data storage means 2 from the ROM writing device etc. through the data input/output means 1, and is first displayed on the display means 4 from the beginning of the data. indicate. The general control means 5 places a cursor at the beginning of the data on the display means 4, and the cursor is moved up, down, left and right using the arrow keys of the operation means 3 to move to the data position to be changed.

For the data on the cursor, use the numeric keypad of operation means 3 and the character of alphabet key IL % f to 1
Enter data in hexadecimal. The general control means 5 replaces the data at the position indicated by the cursor in the data storage means 4 with the input data, and rewrites the display of the change section on the display means 4. In the display means 4 of FIG. 2, the cursor is placed at the beginning 0 of the data, and the cursor is moved to the right four times using the arrow keys on the operation means 3 of FIG. At this time, the cursor is 3
If you enter 4 at 2 of the 2th data 2G, and enter 4 using the numeric keypad of the operating means 3, 2 will be replaced by 4, and the 3rd dot in the character display will be changed to the ASCII character L.

In addition, the control keys of the operation means 30 include insertion, deletion, string search, numerical search, string replacement, output control, page turn,
Comprehensive control means 6 for page return and designated address display functions
The general control means 5 sends processing and requests to the data storage means 2, the display means 4, and the data input/output means 1 according to their respective functions.

The editing work is completed by pressing the end key.

Effects of the Invention As described above, the present invention stores data in any format input from the data input/output means in the data storage means, displays it on the display means together with data position information, and displays the data on the operation means. The characters and arbitrary data in the data storage means can be processed and output by performing processing corresponding to data movement and editing instructions from the data storage means. By employing the above configuration, the operability when restoring data on the ROM writing device, external storage device, and communication line can be significantly improved with a simple configuration.
