DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an electronic device interconnection system according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows the configuration of an interconnection system for electronic equipment according to an embodiment of the present invention. The electronic device interconnection system includes a computer 1, a printer 3, and a word processor 4.

The computer 1 has a source program whose function is improved (upgraded) as compared with the program of the printer 3, and also translates various program languages and rewrites them into a predetermined program language (the present embodiment). In this case, for example, it is connected to the language conversion device 2 (for converting Fortran, Kobol, etc. into C language) (may be built in).

The printer 3 includes a head drive unit 5 and a print head 6 for performing a printing operation in accordance with an image signal (usually a code signal) from a word processor 4, and an I / O for inputting and outputting signals to and from a control unit. An interface 7, a ROM 8 storing a predetermined program, and a C that performs various controls by executing predetermined calculations based on the program in the ROM 8
PU9, a compiler memory 10 storing a compiler for converting a C language source program into an object program, and a rewritable EEPROM storing the object program converted by the compiler memory 10 as appropriate
An OM (flash ROM) 11 is provided.

The operation of the electronic device interconnection system of the present invention will be described below with reference to the flowchart of FIG.

First, the program of the printer 3 (ROM 8
A program with improved functions, that is, an upgraded source program is stored in, for example, a memory of the computer 1 from a floppy disk or the like.

Next, a source program transfer mode is input from a keyboard (not shown) of the computer 1. When the transfer mode is input, the printer 3 requests the computer 1 to transfer the source program (step 50).

When the computer 1 receives the transfer mode request from the printer 3, it asks the printer 3 about the program language of the printer 3 (step 51). On the other hand, the printer 3 answers the computer 1 in the programming language of the printer 3 (C language in this embodiment) (step 52).

When the computer 1 inputs the program language of the printer 3 from the printer 3, the computer 1 determines whether or not the program language is the same as the program language of the source program (step 53). As a result, if they are common, the process directly proceeds to step 55, and if they are not common, the process proceeds to step 54.

In step 54, the source program is once transferred to the language converter 2 connected to the computer 1, where the source program is translated, rewritten into the program language (C language) of the printer 3, and returned to the computer 1 again. .

When the source program becomes common with the programming language of the printer 3 in this way, the computer 1 transfers the source program to the printer 3 in step 55.

When the transfer is started, the source program is inputted to the control means via the I / O interface 7 of the printer 3, and the C language source program is converted into the object program by the compiler stored in the compiler memory 10 here. (Step 56).

When the upgraded source program is converted into an object program, this object program is converted into a CP based on a program in ROM 8.
The data is stored in the EEPROM 11 under the control of U9 (step 57), and the transfer of the source program is completed.

When the source program is transferred to the printer 3 and the source program is stored in the EEPROM 11, the printer 3 stores the program in the ROM 8 and the EEPROM.
A predetermined operation is performed based on the upgraded program stored in the PROM 11. Therefore, it is possible to improve the function of an old product that has been used without replacing it with a new product.

The printer 3 is equipped with a CPU 9 having higher performance than the word processor 4 and the like, despite being an electronic device having a low operating rate. Therefore, the printer 3
If the word processor 4 is operated using the CPU 9 and the upgraded program stored in the EEPROM 11, the high-performance components of the printer 3 can be used effectively.

On the other hand, in the electronic device interconnection system shown in FIG. 1, the printer 3 receives the program and data from the computer 1 and stores the program and data in its own large-capacity memory, and then performs high-speed search or high-speed sorting of the transferred data. Is performed by the CPU 9. Here, the printer 3 functions as one computer.

As a matter of course, the printer 3 may be replaced by one computer. The result of the high-speed search is printed by driving the print head 6 or returned to the computer 1.

If the data transferred from the computer 1 is image data, the image data is rotated, enlarged, reduced,
Processing such as rendering is performed, and the result is returned to the computer 1. Thus, when the printer 3 is not operating as a printer, the processing capability of the computer 1 can be enhanced by utilizing the resources of the printer 3.

When data is transferred from the computer 1 to the printer 3, the computer 1 can compress and transfer the data. The compressed data is expanded by the printer 3. As a result, the transfer speed can be increased.

When the printer 3 has a scanner, image data read by the scanner can be stored in a large-capacity memory, and then the data can be compressed and transferred to the computer 1. At this time, the transfer speed can be increased.

FIG. 3 shows a second embodiment of the present invention. The electronic device interconnection system according to the second embodiment is configured by connecting a computer 1 and a word processor 4.

The word processor 4 includes a head drive unit 12 for reading / writing image information from / to a floppy disk 13A, a magnetic head 13, a display 14 for displaying images, and a keyboard for inputting sentences and various commands. 15, an I / O interface 16 for inputting / outputting signals to / from a control unit described later, a ROM 17 storing a predetermined program, and performing predetermined calculations based on the program in the ROM 17 to perform various controls. A CPU 18, a RAM 19 for temporarily storing information read from the floppy disk 13 A, a compiler memory 20 for storing a compiler for converting a C language source program into an object program, and an object program converted by the compiler memory 20. Rewriting to store as appropriate It is configured to include a capability of EEPROM 21.

With such a configuration, it is possible to improve the functions of the word processor of the old product that has been used without replacing the word processor of the new product that has been upgraded by transferring the program described in the first embodiment. it can.
