JPS6025622Y2 - Decimal-n-ary data mutual conversion device - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an indicium-n-adic data mutual conversion device that can effectively convert the expression forms of data having different expression forms, such as indicative numbers or hexadecimal numbers.

In general, for example, by converting 6 cans of angle data expressed in degrees, minutes, and seconds into impression data, or conversely, by converting angle data expressed in impression into ω-adic data. , it is converted into a format suitable for the purpose and used for various calculations.

For example, in companies, etc., management of employees' bone movement time,
Or, when calculating wages, bone movement time (6 tatami data)
This is converted into impression data to calculate bone movement time and wages.

Therefore, small-sized electronic computers incorporating such a device for mutually converting data of print numbers and 6 bits have been put into practical use.

However, with this type of calculator, for example, if you want to convert injin data to 6 jo data, you must operate the + key, and conversely, if you want to convert 6 jo data to decimal data, you must press the INV key followed by the E luck 1 key. I was trying to operate it.

For this reason, the key operations and number of operations for each conversion of decimal - 0 base, 6 bits → Kawashin are different, which may lead to incorrect key operation, or when converting alternately such as Injin → 6 bits → Kawashin. The disadvantage was that it required complicated key operations and was not easy to operate.

This idea was made in consideration of the above-mentioned circumstances, and it is an injin-n-adic system that allows data with different expression forms to be mutually converted interactively by simpler key operations. The present invention provides a data mutual conversion device.

An embodiment of this invention will be described below with reference to the drawings.

In FIG. 1, a key input unit 1 is equipped with a number key 2 for setting keys □□□, a conversion key fF3a, a normal function key 3b, and the like.

Numerical data obtained from the numeric key 2 is input to the register 4 via an AND gate 5 and an OR gate 6 that operate on the input gate of the register 4.

Further, the operation signal of the conversion key date 3a is inputted to the control section 7 and the pinal counter 8.

The binary counter 8 is triggered by the operation signal of the conversion key 23a, and its contents are ro, →r 1. + $ r O yo → 11 yo song.

The operation signal of the function key 3 is input to the control section 7 via the pass line B.

The control unit 7 includes various micro-instructions that control the operation of each circuit.
For example, it outputs the microinstructions a''d shown in the figure.

Microinstruction a is input as a control signal to AND gate 9 which controls the input gate of register 4.

The output data of the data conversion circuit 10, which will be described later, is input to the second input terminal of the AND gate 9, that is, the microinstruction a is being outputted (the ``1'' signal at the binary logic level).
When the output data of the data conversion circuit 10 is input to the register 4
The information is entered and stored in the .

The micro-instruction is inputted to the AND gate 5 as a control signal, and therefore the numerical data is written into the register 4 only during the output of this micro-instruction.

Microinstruction C is input as a control signal to AND gates 11 and 12, and the AND gates 11 and 12
The output of the pinal counter 8 is inputted directly or via the inverter 13 as another control signal to each of the terminals.

Further, data in register 4 is supplied to both AND gates 11 and 12.

Therefore, when the content of the binary counter 8 is r()J during the output of the microinstruction C, only the AND gate 12 out of the AND gates 11 and 12 is deregulated;
The data in the register 4 is inputted via an AND gate 12 to a sexagesimal-decimal conversion circuit 14 in a data conversion circuit 10.

On the other hand, when the content of the binary counter 8 is rIJ, only the AND gate 11 is deregulated, and the data in the register 4 is inputted to the 1-jo→input conversion circuit 15 in the data conversion circuit 10 via the AND gate 11. It looks like this.

The microinstruction d is input as a control signal into the AND gates 16 and 17, and the output of the binary counter 8 is input to the AND gate 16 via the inverter 13, and the output of the binary counter 8 is input to the AND gate 17.
The output of is input directly.

Therefore, the content of the binary counter 8 is 10. When microinstruction d is output when , AND gate 16,1
7, only the AND gate 16 outputs a "1" signal, and this "1" signal is input to the 604+decimal conversion circuit 14 as an operation command.

On the other hand, when the microinstruction d is output when the content of the binary counter 8 is rl, the "l" signal is output only from the AND gate 17, and this "1" signal is sent to the inshin-6 pass conversion circuit 15 for calculation. It is now entered as a command.

In other words, in this data conversion circuit 10, when the content of the binary counter 8 is r
A data conversion operation is executed to convert the data into decimal data, and when the content of the pinal counter 8 is rl y, only the impression → 6 mallet conversion circuit 15 operates, and the impression data sent from the register 4 is converted to 0. The data converter is configured to perform a data conversion operation to convert to binary data.

The pinal counter 8 is reset by a reset signal output from the control unit 7 when a clear key (not shown), which is one of the function keys 3b, is operated or when the power is turned on, and its contents are changed to rJ. Set.

Further, the data in the register 4 is sent to the display unit 18 and displayed.

Next, with reference to FIG. 2, an example of the operation of this embodiment is shown in which, for example, the impression data '4.26 degrees yo is converted to the 6 stroke data 14 degrees 15 minutes a second yo, and this inverse conversion is performed. The explanation will be based on.

First, the binary counter 8 is reset in advance and its content is rOJ, and the printing data "4.26 degrees yo" is input into the register 4 by operating the number key 2 of the key input section 1.

In this case, number key 1, decimal point key country, number key 12
! When v.Raku is operated in sequence, a microinstruction is output at a predetermined timing, the AND gate 5 is deregulated, and the numerical data "4.261" is written into the register 4.

The written numerical data '4.261 is then displayed on the display section 18.

FIG. 2a shows the contents of the binary counter 8, register 4, and display section 18 at the end of this key operation.

Next, when the conversion key [m3a is operated, the operation signal causes the content of the pinal counter 8 to increment to 1L.

Therefore, the AND gates 11 and 17 to which the output signal of the binary counter 8 is directly applied are deregulated.

Then, microinstructions C, d, and a are output from the control unit 7 at predetermined timings, and the data in the register 4 is
4.26 yo is input to the impression-to-input conversion circuit 15 via the AND gate 11, and an arithmetic command is output from the AND gate 17 to the W-adism to 6-bit conversion circuit 15.

Therefore, in the printing to sexagesimal conversion circuit 15, the decimal data "4.26 degrees yo" is converted to sexagesimal data r4 degrees 1 powder 36 seconds.

And this conversion data is AND gate 9, OR gate 6
via the register 4 and stored therein.

FIG. 2 shows the contents of the register 4 at this point.

Next, when the conversion key 23a is operated again, the operation signal causes the content of the binary counter 8 to change from 71 to rO, and the output signal is inverted by the inverter 13, so that the AND gates 12 and 16 are released from regulation.

Then, microinstructions c, d, and a are output from the control unit 7 at predetermined timing, and the sexagesimal data 1 in the register 4 is outputted from the control unit 7.
4 degrees 15 minutes a second yo is input to the print-to-print conversion circuit 14 via the AND gate 12, and at the same time, an arithmetic command is output from the AND gate 16 to the sexagesimal-to-zero conversion circuit 14.

For this reason, in the 6-jo → print/input conversion circuit 14, the 6-jo data r
4 degrees 1 minute a second yo is converted into decimal data "4.26 degrees yo", and this converted data is sent again to the register 4 via the AND gate 9 and the OR gate 6 and stored therein.

FIG. 2C shows the contents of the register 4, etc. at this point.

Next, when the conversion key [←3a is operated again, the content of the binary counter 8 changes from r''OJ to rIJ, and in the same manner as described above, the impression data '4.26 degrees Yo is changed to 6 (2) data 1.
It is converted to 4 degrees 15 minutes 36 seconds yo.

FIG. 2d shows the contents of register 4, etc. at this point.

On the other hand, when inputting ω-adic data first and converting this data to W-adic data, first set the contents of the pinal counter 8 to 11 yo, then input the data of the incinal number from the key human power section 1, When the conversion key 1-+j3a is operated, the 6-bit data is converted to 0-decimal data in the same way as described above.

It should be noted that the data conversion circuit 10 is not limited to the above-mentioned embodiment, but may be one that is capable of converting time (hours, minutes, seconds) into a notation number, or the inverse conversion thereof, or a radian, Dalacian, etc. Any device that can mutually convert data having different expression forms, such as having a function of converting data other than hexagonal numbers and 0-base data, may be used.

In addition, in the above embodiment, the decimal → 6-jo conversion circuit and the ω-adic →
Although the 1-book conversion circuit is provided separately, a conversion circuit that performs mutual conversion using an accumulator register and an arithmetic circuit may be configured, and various application forms are possible without departing from the gist of this invention. It is.

As explained in detail above, this device can be used in data conversion operations by making it possible to mutually convert data representation forms that have at least two types of representation forms in a binary manner according to the operation of a conversion key. This method has various advantages, such as requiring fewer keys than in the past, making key operations easier and preventing erroneous key operations, and being very convenient in practice.
