One power supply unit is to provide electric power to use for total system;

It is characterized in that also comprising a system conversion treating apparatus, it is connected on the above-mentioned micro processor, the data of importing a certain system when above-mentioned keyboard is to this micro processor, when being stored in above-mentioned random access memory simultaneously, this system conversion treating apparatus is promptly by this micro processor, carry out the computing conversion with the data that captures in this random access memory, other other three hex value that to change gained then is presented on the LCD by the LCD driver of this microcomputer controller again, reaches to show four kinds of different system scaled values simultaneously on the display screen of LCD.

Now conjunction with figs. has one of the computing machine that can show four a kinds of different system scaled values simultaneously preferred embodiment with of the present invention, is described in detail as follows, and in the hope of to advantage of the present invention, purpose or feature can obtain further fully to understand.

Fig. 1 is the hardware system calcspar that the present invention has the computing machine that can show four kinds of different system scaled values simultaneously.

Fig. 2 be the present invention have can show four kinds of different system scaled values simultaneously computing machine wherein program when treatment conversion, the view of institute's foundation.

Fig. 3 is that the present invention has the program control flow chart that can show the computing machine of four kinds of different system scaled values simultaneously.

Fig. 4 (a)～(c) is that the present invention has the computing machine that can show four kinds of different system scaled values simultaneously, the wherein example schematic on the display screen.

See also Fig. 1, the present invention has can show four kinds of different systems but equivalent computing machine simultaneously.Mainly be to utilize advanced electronic technology to add that microcomputer program control develops to form, comprise a micro processor 1, one finger-impu system 2, one LCD 3, one random access memory, 4, one power supply units 5 and system scalers 6; This micro processor 1 control core that is total system wherein, include the running of procedure code with the control total system, and the driver of a LCD is also contained in this micro processor 1 inside, and the data that can directly export the desire demonstration is in above-mentioned LCD 3; 4 numerical value that store input of this random access memory can be for reading at any time or writing; 2 devices that provide as data input of this finger-impu system, but by these finger-impu system 2 user's input data and operational orders; 5 of this power supply units provide electric power to use for total system, to keep the normal operation of system; And this system scaler 6, it is to be connected with above-mentioned microcomputer controller 1, carrying out the conversion of scale-of-two, scale-of-eight, the decimal system and sexadecimal equivalence, and four kinds of different hex value after will converting see through this microcomputer controller 1 and are shown in LCD 3 simultaneously.

By above-mentioned structure, when the user desires converting data in input, above-mentioned micro processor 1 will be obtained the numerical value of input by keyboard 2, and it is put into random access memory 4, simultaneously the data of input is delivered to LCD 3, for process of checking input data and correctness; And after this random access memory 4 was deposited the data that finishes of input, micro processor 1 was promptly done computing and conversion according to this system scaler 6 of value order of this input data; Then, resulting other other three hex value of conversion is presented on the LCD 3 by the LCD driver of microcomputer controller 1 again.

Moreover, how obtaining different system conversion values for further specifying the present invention, the spy illustrates in detail as the back:

Now be example to import one with metric numerical value 125, when micro processor 1 is received the instruction number that begins to change by keyboard 2, judge earlier that promptly the numerical value 125 of input is decimal value just now, calculating hexadecimal value in the mode of division then is 7D, and formula is as follows:

125 ÷ 16=7 remove 13, and wherein divisor 13 is to be D in sexadecimal, are gained so be combined as 7D with 7 with D.

The scale-of-eight value is that per three bits (Bit) are combined into a units in the sexadecimal again, therefore utilizes this mode that 7D is expressed as 01111101, is begun by lowest order digit then, takes out three bits at every turn and comes out to be combined into octadic figure place, promptly 101 draws 5; 111 draw 7; Reach 01 and draw 1, therefore can draw the scale-of-eight value is 175.Along with obtaining of scale-of-eight value, then binary value also can be used its mode and obtains, and difference goes out a bit and represents a units as long as move (Shift) at every turn only when the conversion binary value.Therefore changing binary value into by hexadecimal 7D is 1111101.

Now with above-mentioned mode, cooperate micro processor 1(8 Bit) and the data structure of inner formula as follows:

Because this computing machine is the show state that is designed to tens, therefore cook up a block space in random access memory 4, do storage for the value of computing gained.The data formats of inventor's design respectively occupies 8 bit groups (Byte) for each numerical value, and its form is as follows:

Wherein the 0th bit group is positive number or negative with this number of noting down, if the 0th bit group is 1, represents that then this number is negative; If the 0th bit group is 0, represent that then this number is positive number.

The 1st bit group is in order to represent the exponential quantity of this number.

The 2nd bit group system is used for when computing, makes the temporary usefulness of Carry.

The 3rd bit group to the 7 bit groups then are the place of numerical value, wherein [10] are the most significant digit number, and [1] is lowest order digit, promptly represent a units with per four bits, because in these four kinds of systems, maximum bit value is " F ", therefore only needs to get final product with the plain expression of four bits, so just can not waste storage space.

Now again with above-mentioned example, promptly metric 125 equal hexadecimal 7D equals octadic 175 and equals binary one 111101 and be example, illustrates in the record situation of random access memory 4 as follows:

See also shown in Figure 2ly again, be the basic transition status synoptic diagram of the present invention, wherein mainly be with the decimal system to the sexadecimal heart that is as the criterion, scale-of-eight and scale-of-two then framework under sexadecimal.For example, when input scale-of-eight value is asked other three hex value, at first obtain its hexadecimal value, obtain decimal value and binary value with this hexadecimal value respectively again, and then utilize micro processor 1 to read the numerical value of operand by random access memory 4, it driver by LCD is simultaneously displayed on four groups of different data on the display 3.Its operational flowchart promptly as shown in Figure 3.

See also Fig. 3 and cooperate shown in Figure 4ly, after this computing machine one start, on the display screen of aforementioned display device 3, promptly occur as the demonstration of Fig. 4 (a) example; At this moment, the user can select cuit with the index " ← " on the mobile display screen by [↑] [↓] button, then with regard to the item selected input value, shown in figure (b); Numerical value can [be imported] button and carry out conversion process after keying in and finishing, and shows the relative value of other three systems simultaneously in display screen, shown in figure (c); And reach the present invention is handled easily, can show the purpose of four kinds of different system scaled values again simultaneously.

In sum, of the present invention have a computing machine that can show four kinds of different system scaled values simultaneously, really can reach the application target of expection by the technology of above-mentioned exposure; And this case does not see publication or public use formerly before application, meets described novelty of Patent Law and practical spirit fully, and the whence proposes novel patented claim in accordance with the law.
