Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a micro combicoater, and particularly to one having an operation function for inputting a program and a monitor function.

[Background technology]

Generally speaking, this type of microphone-in-the-mouth computer uses the alphabet 2 as the operating section for inputting programs.
A keyboard with at least 40 keys, including 6 characters and 10 numbers, was required. An operation section having such a large number of keys inevitably occupies a large amount of space, and this has been a major impediment to miniaturization of this type of microcomputer. Further, as the keyboard as the operation unit is miniaturized, the individual keys become smaller and more difficult to use, and this aspect also limits the miniaturization of the micro combicoater. Further, as described above, a keyboard having a large number of keys is not necessarily easy to use, and requires considerable practice to become accustomed to operating it. Furthermore, even if you are used to it, in principle, you must use both hands to operate this type of keyboard. Therefore, it is very easy to operate it with one hand or while holding a pencil. However, the input operation for a program is completely different from normal typing, in that it is performed while referring to materials with one hand, and while thinking while holding a writing instrument such as a pencil in the hand that operates the keys. Therefore, the multi-key keyboard described above tends to significantly impede the efficiency of program input.

[Purpose of the invention]

This invention was made in view of the above problems.
The purpose of this is to provide a microphone that can perform program input operations and monitor functions while achieving significant miniaturization, as well as improve program creation and input efficiency. There is a need to provide computers.

The above and other objects and novel features of this invention can be found in the description of this specification and the attached drawings [Summary of the Invention] A brief overview of typical inventions disclosed in this application is as follows: That's right.

That is, in a microcomputer equipped with an operation section for inputting a program and a display device for monitoring, the first method is to display a plurality of command words of a programming language on the display device while alternating them in a predetermined order. It has an operation section and a second operation section that performs an operation for specifying the instruction word displayed on the display device by the first operation section, and the instruction word specified by the second operation section is programmed. By storing it in a storage device as a part of the program, it is possible to provide program input operation and monitoring functions while achieving significant miniaturization, and also to achieve the purpose of increasing program creation and input efficiency. It is something to do.

〔Example〕

Hereinafter, typical embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference numerals.

FIGS. 1 and 2 show a microcomputer according to the present invention.
An example of one embodiment is shown below. The -r4 black computer 10 shown in the figure first has a CPU (
central processing unit)12. System ROMI 4,R

, a main body portion 30 including a display controller 20, etc.
has. A display device 22 and a keyboard 24 are connected to this main body portion 30, forming an integrated microcomputer system as a whole. Further, if necessary, it is configured so that an external storage file 26 such as a tape recorder, a tote recorder, or a floppy disk drive can be connected.

Here, the main body portion is integrated into a single semiconductor chip as a single-chip microfist computer.

The system ROM 14 also contains an assembler program, a disassembler program, and a BASIC program, in addition to an operation program for causing the micro combinator to perform the operations described below.
Boot programs are written to run high-level programming languages such as In the assembler mode, the 21 monics corresponding to the machine language are alternately displayed one by one on the display device 22.

As shown in FIG. 2, the display device 22 serving as a monitor includes a bimonic display section 22a that displays only one monic corresponding to a machine language in the assembler mode, and a bimonic display section 22a that is attached to the bimonic. It has a data display section 22b that displays data. In this embodiment, the keyboard 24 as an operation section includes two keys 24a and 24b as a first operation section, one key 24C1 as a second operation section, and a micro-controller such as an assembler or disassembler. It only has a function key 24d for switching the operating mode of the computer.

The keys 24a and 24b of the first operation section are connected to the display device 2.
An operation is performed in which the two-monics and data displayed on 2 are alternately displayed one instruction word at a time. That is, first,
When the key 24a is pressed once, the next monic appears, and when the key 24a is pressed once more, the next monic appears, and in this way, multiple types of monics are alternated one after another. will be displayed. Further, if the key 24a is held down, the displayed 21 monics change continuously and stop when the suppression operation is stopped. The adjacent key 24b can also be used to similarly change the displayed two-monics one by one. In this case, the alternation order of the twenty-one monics is carried out in the alphabetical order of the twenty-one monics, and when the key 24a is operated, the alternation order is from A to Z, and when the key 24b is operated, the alternation order is from Z to A. They are scheduled to be replaced sequentially.

Therefore, by operating the two keys 24a and 24b, it is possible to select any one of the two-monics and display it on the two-monics display section 22a of the display device 22.

As described above, once an arbitrary binary has been selected and displayed using the two keys 24a and 24b, the key 24c of the second operating section is depressed. Then, the machine language corresponding to the selected 21 monic is input and stored in the above 1 (AM16). Then, if the machine instruction corresponding to the 21 monic is a one-word instruction, the first operation is performed again. keys 24a, 24b and # of the second operation section.
-24c, repeat the same operation. Further, if the input command is a command of two or more words accompanied by data, the first operation section 24a, 241) will display the data display section 22. The mode is automatically switched to a mode for selecting data displayed in b. That is, in the embodiment, first, one of the characters representing a hexadecimal number from 0 to F is displayed in the leftmost column of the data display section 22b, and by operating the keys 24a and 24b, that character can be changed from 0 to F or It is possible to sequentially change from F to 0 one by one. When an arbitrary character is displayed and the key 24C of the second operation section is operated, the character selected and displayed on the left end is input and stored in the RAM 16. After that, select and input the hexadecimal characters displayed in the display column 9 to the right in the same way, and repeat the same operation for the required number of digits to input any hexadecimal data. Perform the operation. When the data input operation is completed in this manner, the mode returns to the mode for displaying the above-mentioned two-monics as a selection and inputting them again. Therefore, the three keys 24a, 24b.

Programs in assembly language can be input simply by operating the 24C. Further, when the function key 24d is depressed, nine modes are alternately displayed in the display column above the key 24d. Then, select and display any mode and press the key 24C of the second operation section.
When the mode is suppressed, the control of the microcomputer shifts to the selected/displayed mode. Therefore, in order to debug an input program, for example, any part of the program can be disassembled and viewed.

As described above, in this embodiment, the operating function for program input and the monitoring function can be provided with only four keys 24a, 24b, 24c, and 24d. Therefore, a large reduction in size can be easily achieved, and for example, a wristwatch type can be easily constructed. Furthermore, it is worth noting that the mnemonics are displayed one at a time in turns, so for example, beginners can recall the 21st mnemonics they have forgotten by looking at the 21st mnemonics that are displayed in turn. , this makes it possible to create or learn programs more efficiently 4
That's what it means. Since the number of keys to be operated is extremely small, programs can be created and entered while referring to documents or smoking a cigarette with one hand, or while holding a writing instrument in the operating hand. can be done comfortably and efficiently.
