Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a program processing method for a computer-equipped device that reads and executes a program selected from a plurality of programs by human power or the like.

[Prior art] A CPU (central processing unit) as a main body of a control unit,
Conventional computer equipment equipped with memory sections of ROM (read only memory) and RAM (random access memory), and input/output circuits that connect various input/output devices such as a keyboard, display, and floppy disk driver. When a floppy disk containing various program data is inserted into the floppy disk driver, by manually typing a program number on the keyboard, the program data corresponding to that program number is read from the floppy disk and executed. It is known what made it so. With this configuration, it is no longer necessary to store a part of the programs necessary for the computer-equipped device in the memory section, and the capacity of the memory section can be reduced.

By the way, in the conventional computer-equipped equipment in which an arbitrary program is selectively loaded and executed by keystrokes or the like, as mentioned above, the program is not loaded until all the information necessary for selecting the program has been input. It was about to start. For example, program number 1
To select program number 0, use the numeric keys to select “1”.
After setting the number "0", the reading of the corresponding program is started when a key, for example, the input key, for determining the numerical data is input, and after the reading is completed, the corresponding program is executed.

[Problems to be Solved by the Invention] As described above, in conventional computer-equipped equipment in which arbitrary programs are selectively read and executed by key personnel, etc., the information necessary for selecting a program is not determined. After that, loading of the corresponding program was started, and the program was executed after loading was completed. For this reason, the entire time required to read the program is spent waiting for the operation, which has the disadvantage of poor processing efficiency.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a program processing method that can shorten the waiting time from program selection information determination to program execution and improve processing efficiency.

[Means for Solving the Problems] The present invention has a storage unit that stores a plurality of programs and an input unit that inputs program selection information, and a program that corresponds to the program selection information that is input via the input unit. When program selection information is input from the input section, reading of the corresponding program from the storage section is started based on the program selection information, and the program selection information is executed by selectively reading from the storage section. If the next program selection information is input from the human resources section without being instructed to confirm, the current program reading operation is stopped and the corresponding program is read from the storage section based on the program selection information input so far. This is a program processing method in which a program is started, and when an instruction to confirm the program selection information is given, a program that has been read from a storage unit is executed.

[Operation] With the program processing method having such a procedure, reading of the predicted program is started at the time when the program selection information is input from the input section.

If the next program selection information is input without being instructed to confirm the program selection information, the current program reading operation is stopped and another program is started based on the program selection information input so far. Loading begins. Therefore, since the reading operation of the corresponding program has already started when the determination of the program selection information is instructed, the waiting time until the reading of the program is completed and the program is executed is shortened.

[Example 1] An example of the method of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of computer-equipped equipment to which the method of the present invention is applied. In the figure, 1 is a CPU as the main body of the control unit, and 2 is a ROM in which fixed data such as programs are stored.

3 is a RAM in which various memory areas such as a number register 31, a program area, 732, etc. are formed as shown in FIG.
, 4 is a keyboard controller to which key signals are input from a keyboard 5 as an input section, 6 is a display controller that outputs display data to a CRT display 7, and 8 is a storage section that accesses a floppy disk 9 to read and write data. The I10 port exchanges signals with the floppy disk driver 1. Here, the keyboard 5 is provided with various keys such as a number key for inputting numerical data such as a program number, and an input key for instructing confirmation of the programmed program number. Further, the floppy disk driver 10 is loaded with a floppy disk 9 or the like on which various program data having program numbers that can be entered using the keyboard 5 are recorded.

” 1 CPUI is the above ROM 2. RAM3. Keyboard controller 4. Display controller 6 and I1
0 ports 8 are electrically connected via pass lines 11, respectively. When a power source (not shown) is turned on, the CPUI controls the ROM 2 and is configured to execute the processing shown in FIG. 3 based on the program stored in the ROM 2. That is, first, in ST (step) 1, the CRT display 7 is drive-controlled to display a preset initial screen (menu screen). Next, in ST2, a key input from the keyboard 5 is waited for.

In this state, if a numeric key is pressed manually, the numerical data corresponding to the numeric key is set in the least significant digit of the numeric register 31 in the RAM 3.

Next, the floppy disk driver 10 is driven and controlled via the I10 port 8 to access the floppy disk 9. Then, reading of program data in which a program number matching the contents of the number register 31 is set is started from the Nobby disk 9. Note that the read program data is stored in order from the top address of the program area 32 in the RAM 3. Also,
This program reading operation continues until the next keystroke is performed.

If the numeric key is pressed again during the program data reading operation, the program reading operation currently being executed is stopped, the contents of the numeric register 31 are shifted upward one digit at a time, and the numeric key is pressed again. Set the numeric data corresponding to the input numeric key in the lowest digit that becomes the area.

Then, in the same manner as described above, reading of program data in which a program number matching the contents of the number register 31 is set is started from the floppy disk 9.

In this case as well, the read program data is stored in order from the top address of the program area 32 in the RAM 3. Further, the program reading operation continues until the next keystroke is performed.

On the other hand, during the program data reading operation, the keyboard 5
If the input key is entered manually, the number register 31
Since the program number corresponding to the numerical data in is determined, the program reading operation currently being executed is continued. When the reading is finished, processing based on the read program is executed. At this time, CRT display 7
Update the display screen to one that corresponds to the program in question.

Note that if the reading of the corresponding program has been completed before the input key is input, the initial screen remains in the preparation state, and in response to the input of the input key, execution of processing based on the corresponding program is started.

In this embodiment having such a configuration, reading of the predicted program is started when the program number as the program selection information is entered using the number keys on the keyboard 5. If a program number is inputted without being instructed to confirm the program number, the current program reading operation is stopped and another program is started based on the program selection information input so far. Loading begins. Therefore, when the confirmation of the program selection information is instructed by the input key on the keyboard 5, the reading operation of the corresponding program has already started, so it takes longer than before to complete the loading and execution of the program. Waiting time will be reduced.

For example, when selecting the program with program number "10", the operator presses the number keys on the keyboard 5 to select rlJ,
The user then enters rOJ and finally operates the input key to instruct to confirm the program selection information (program number). In this case, first, when the number key "1" is operated, the floppy disk driver 10 accesses the floppy disk 9 and starts reading the program data to which the program number "1" is set. Next, when the number key "0" is operated, the reading operation of the program with the program number "1" is stopped. Then, reading of the program data to which the program number "10" inputted up to that point is set is started.

That is, at this point, the reading operation of the desired program is started. Thereafter, when the input key is operated, the reading operation of the program data of the program number "1o" is continued, and upon completion of the reading, the corresponding program is executed.

Therefore, the reading of the desired program has already started before the confirmation of the program number, which is the program selection information, is issued, so the waiting time from the confirmation of the program selection information until the program is executed is shortened. . As a result, the processing efficiency of the system is improved.

Note that the method of the present invention is not limited to the above embodiments. For example, in the embodiment described above, the floppy disk 9 was shown as a medium on which various programs are recorded, but the medium is not limited to this (for example, a hard disk or the like may also be used. In addition, in the embodiment described above, the program selection information is Although input is performed manually, it can also be applied to input using an input device other than a keyboard.It goes without saying that various modifications can be made without departing from the gist of the present invention.

[Effects of the Invention] As described in detail above, according to the present invention, it is possible to provide a program processing method that can shorten the waiting time from after program selection information is determined until program execution, and can improve processing efficiency.
