Description

Detailed Description of the Invention (Technical Field) The present invention provides a computer that can perform exponent processing by representing a numerical value with a mantissa part and an exponent part, and is capable of outputting a voice that takes into account the scale of the numerical value of the exponent part. Regarding computers.

(Prior art) Generally, in a computer capable of performing exponent processing, the numerical state of the exponential method is represented by a mantissa and an exponent, and the mantissa and exponent are distinguished by a Planck sign or a negative sign. Is displayed.

Since the numerical value in the exponent part is not displayed together with its scale, it would be extremely convenient to use it if it were possible to make a computer say the numerical value in the exponent part, taking the scale into account, without increasing the number of keys. (Objective) The present invention has been made in view of the above-mentioned conventional calculator, and provides an audio calculator that can output audio in the form of adding scale to the numerical value of the exponent part in exponent processing without increasing the number of operation keys of the calculator. The purpose is to

(Example) Fig. 1 is an external perspective view of a voice computer used in the present invention, in which 1 is the computer main body, 2 is a display section, 3 is a power switch, 4 is a speaker, and 5 is a voice generator. key, and by pressing this key, the contents of the calendar number and the calculation results are outputted by voice from the speaker.

6 represents a numerical value or a function key.

Figure 2 is a block diagram for controlling the voice calculator. KB is a keyboard section that has a group of numeric keys (10K) and a group of function keys (FK), and signals corresponding to keys operated on this keyboard section are Code conversion is performed by encoder EC. The output of this encoder EC is sent to the arithmetic control unit CPU and the output register OR, and the information and the arithmetic result obtained by the keyboard unit KB are sent from the output register OR to the address counter AC via the arithmetic control unit CPU. Sent. Address counter A
One end of C is connected to a storage ROM, and a storage ROM
Digital code words to be extracted as phonetic information are hidden in advance, and the address counter AC addresses specific parts of these code words in a predetermined order. The storage device ROM uses a read-only memory, and by addressing this memory, a desired digital code word corresponding to the above-mentioned tatami number information or operation result information is retrieved, and digital/analog (D/A )
The code word is converted into audio information using a converter, a low-pass filter LPF, a driver, and a speaker. Next, a method for outputting numerical information using the exponential method by voice will be described.

In general, in a computer that can perform exponent processing, numerical information in the exponential system is represented by a mantissa and an exponent, as shown in Figure 3 (a). The divisions are 1 and 2 (that is, 12 proposals out of 10).

These pieces of information are stored in the output register OR, and a discrimination signal such as Planck or negative sign information is introduced between the two assigned pieces of information (between the mantissa part and the exponent part) to distinguish between the two pieces of information. Ru. Now, let's set the Planck information to 5 bits "01111" to distinguish it from other numerical information.
”, negative sign information is also assumed to be “11111”. A code signal representing this blank or negative sign information is sent to the address counter AC, and if the blank code is “01111”, the mantissa part stored in the storage device is sent to the address counter AC. and the exponent separator (
For example, “bee”, “kakeru” or “silence for a certain period of time”)
After addressing the digital code word indicating 1 of 10
Address the code word that corresponds to "Juno", which represents a miniature garden.

The addressed code words are sequentially output from the storage device,
After generating the mantissa part from a speaker via a D/A converter, the numeric value of the exponent part and its scale are uttered as "ju/, junijou". In the case of the mouth, the same goes for ``Go ten san roku nana kakeru (or bee) jiyuno minus juichijo.'' FIG. 4 shows a circuit device 4 for differentiating between a mantissa part and an exponent part and outputting different sounds, and the same parts as in FIG. 2 are designated by the same reference numerals. In the case of numerical information in the exponent format, the numbers in the mantissa part need only be uttered one digit at a time, regardless of the scale, whereas the numbers in the exponent part need to be uttered with the scale taken into account. There is. Therefore, as mentioned above, in order to distinguish between the mantissa part and the exponent part, the register 0R is provided with the Planck code "0".
1111" or the negative sign code "11111" is stored, so either of these codes is detected through the AND gate g or g2, and the power of this world is detected through the OR gate ○ and the AWARD gate scale, The flip-flop F, is set by the detection force. When the flip-flop F, is set, the set output ■ is generated, and from then on, it is determined that the value of 0 is the exponent part, and the contents of the address counter AC are the mantissa part. Even if it is the same as in the case of generation, by applying the set signal @ of the flip-flop F to the storage device ROM and addressing it, information with the scale taken into account is selected. After uttering information, jo (multiplication) must be uttered.In other words, set output a is generated when the content of the third digit of the output register OR is 01111 or 11111.The generation of this set output signal a causes 3rd digit of output register OR, 2
To make the audio output of the first digit different from the audio output of other digits. The CPU outputs the contents of the output register OR one digit at a time starting from the most significant digit, and outputs the address information of the storage device ROM corresponding to the code to the address counter. If the set output signal a is generated, for example,
Address information indicating "beep", "kakeru", or silence for a certain period of time is output to address counter AC, and then address information corresponding to "juno" is output to address counter AC. After that, the third digit code of the output register OR
Do'ko compatible audio (e.g. silence or "minus")
Outputs the address information of 2 to the address counter, then 2
The address information is sequentially outputted to the address counter AC so that the first digit is outputted as a voice with the voice of the word representing the scale added. Furthermore, the address information of "Jew" is output to the address counter AC. Further, in the above embodiment, numerical information of an exponential method having a mantissa part and an exponent part was described, but of course it is also possible to output in voice the n plan of An, A, which has only an exponent part, such as in a power calculation. be.

(Effects) As explained above, according to the present invention, there is provided a register that stores numerical information representing a mantissa and an exponent, discrimination information that distinguishes the mantissa, and first audio information corresponding to the numerical information. and second voice information corresponding to additional information for adding a scale to the numerical value of the exponent part. Since it is provided with an output control device for reading out separately and a means for selecting the address of the second voice information stored in the storage device based on the discrimination information, the place value is added to the numerical value of the exponent part. A small computer can be obtained without increasing the number of operation keys of the computer.

It is particularly suitable for use in functional voice calculators.
