Description

Technical method to realize Chinese sound-data coding

The present invention relates to a kind of harden software method, especially in order to realize the technical method of Chinese coded sound scheme.

Number of patent application is that 85100087 Chinese coded sound scheme is after identifying, because of its scheme simply, easily learn, need not memory coding planning and liked by the amateur typing personnel at different levels, age and accept, simultaneously, for professional typing personnel provide Chinese character input method fast, thereby applied very soon.But increase along with the user, a large amount of appearance of new architecture and improving constantly of customer requirements, originally be comprised totally of software " Chinese coded sound " method that realizes, expose its defective and deficiency gradually, big as taking up room of internal memory and hard disk, display speed is slow, and hard disk serious wear etc. cause degree of being practical not high.

The objective of the invention is to improve the implementation method of " Chinese coded sound " scheme,, avoid the wearing and tearing of hard disk, reduce taking up room of internal memory and hard disk, enlarge the scope of application of original system, improve its degree of being practical to improve the display speed of words.

The present invention is developed into a cured plate with Chinese coded sound scheme Chinese information processing system, cured plate is made up of a Chinese Card (TM sound is counted the Chinese system card) and corresponding support programs, and Chinese Card is then by storer, and storer is deciphered and control, I/O decoding, element circuits such as memory-mapped sector address constitute.Each ingredient to Chinese Card is illustrated below;

1. reservoir part; 8 28 pin sockets are arranged on the plate, can hold the storage capacity of maximum 512K byte, solidified all desired datas, comprise the word table of Chinese coded sound scheme with 8 27512EPRON chips, the disyllabic word table, the triphone vocabulary, the quadrisyllable table is failed to see forms such as word table.。Two 40 pin sockets are used for GB character library (whole Chinese characters of 16 * 16 GB GB2312-80 basesets) or expansion, see Fig. 1, and after the address bus was stable, its control line was opened the control end of corresponding data place chip, finishes reading of its data by CPU.

2. reservoir decoding and control: see Fig. 2, latched the most-significant byte of address bus among its LS373, when reading of data, just chosen corresponding storage chip like this, during afterwards data processing, its corresponding data-bias address and latch address addition, just can obtain the corresponding data in this memory chip, wherein two LS283 are address adder, address after adding is directly deciphered to chip by address wire, or convert the chip controls line to by LS138, control corresponding selected chip.

3.I/O decoding part: Fig. 3 circuit has been formed the code translator of I/O, and wherein the purpose of LS85 is in order to make used I/O address carry out necessary adjustment by the people easily, clashes with the system I/O address avoiding, and increases the suitable ability of Chinese Card.The decoding output of I/O address removes to control the data latching of LS373, under the cooperation of this decoding scheme, can be latched among the LS373 by the most-significant byte of data bus with the address, and the mapping that is used for the back is read.

4. memory-mapped sector address: Fig. 4, for fear of the conflict that the application heap address takies, this circuit can be selected different memory-mapped sector addresses by switch, thereby makes circuit more perfect.

5. also be added with on the plate buffer compartment from, decoupling filtering and some other control bus and data bus.These functions are used for improving stability and the antijamming capability and the correct transmission of control data on bus of Chinese Card.

From the above, this Chinese Card characteristics are:

1. the mode that reads because of Chinese Card has adopted the memory-mapped mode, makes its reading speed reach the fastest.

2. character library decoding part need not to adopt special-purpose decoding scheme chip, and velocity ratio is also faster, and the same with other data read mode, has both simplified circuit, has reduced cost again.

3. character library can arbitrarily be matched as required.

4. capacity has bigger expandability.

Be made up of three parts with the corresponding support programs of Chinese Card, it is respectively system software, and indexed table generates software and assistant software, is respectively described below:

By last figure as can be known, software Development is actually former western language DOS(disc operating system (DOS)) transformation of Chinesizing, mainly contain demonstration, keyboard, three interrupt modules of printing, they have finished the input of western language and Chinese character respectively, processes such as demonstration and printout.Because the quality of these modules is directly connected to the efficient of system, speed and capacity are had relatively high expectations, so part is worked out with assembly language.

2, indexed table generates software: the effect of these softwares is that raw data is carried out various processing, and being transformed at last can be for all kinds of form of system program retrieval usefulness, and this process workload is big, and is miscellaneous and easily make mistakes.Raw data is revised this process of back and also can be repeated to do, so with manually can't accomplishing, but owing to less demanding to speed and EMS memory occupation amount, so mostly adopt BASIC to write.By original spreadsheet, ordering software, indexed table generates software and merges software to be formed.

3, assistant software: make speech software for the user provides an environment of making the speech word simply and easily, can make things convenient for the special requirement of all types of user.

By the new system that Chinese Card and respective support software constitute, optimize transformation and enlarged former software systems, hardware supported is provided, brought plurality of advantages and good effect:

1, simplified and traditional body word code is unified, owing to be the input of pure tone sign indicating number, so can accomplish that for the simplified Chinese character or the complex form of Chinese characters coding is unified, the demonstration restoring function (Chinese phonetic alphabet and phonetic symbol) no matter simplified and traditional body type families system has all improved when Two bors d's oeuveres is imported also can be changed by a key, thereby it is readable accurately that its group code and prompting are all had, the user can accomplish: see that word knows sign indicating number, see the sign indicating number character learning "; group code nature; easily; can make human brain to the thinking of language and the key entry activity of staff, organically molten is one has alleviated the burden of typing personnel inputs greatly.

2, Chinese character input speed is fast: double spelling key-position input method (concrete strong position design is seen Fig. 5) has been adopted in strictness during owing to input, and three words, four words, multi-character words and 240 high frequency words only are to be imported with the initial consonant of word, shorten its code length greatly, through a large amount of vocabulary (120,000) that optimizing the arrangement of in addition, input is selected in multi-level prompting, improved the input speed of phonetic transcription greatly, through actual measurement, giving birth to (the former machine of not going up) the fastest input speed through graduating from junior middle school of training in three months reaches more than per minute 400 words, general speed is between per minute 200 to 300 words, has broken to it is believed that sound sign indicating number phonetically similar word is many and traditional concept that input speed can't increase substantially.

3, easy and simple to handle: the native system operation is basic consistent with CC-DOS, has used the people of Chinese information processing system to be convenient to operation, and front and back page operations word preface is constant, convenient memory is suitable for touch system, is suitable for listening beating, the function that automatic repetition the last character is arranged in the system, convenient tabulation or pleonasm input.

4, expandability: arbitrary input mode all can be seted out arbitrarily in the native system, and expands other input method easily.

5, can import illiterate: one of weakness of sound sign indicating number is, if the word of this input is not familiar with, then can't import.To be head it off carried out decomposing the coding of importing with initial consonant of font to GB secondary word (primary word one dish all can be familiar with) to native system, thereby solved illiterate input problem.If input " distant and out of sight word ", the initial consonant of then available " wood " word and " day " word is imported, and coding is " NR ".The new system of Chinese Card the key technical indexes:

1, Chinese Card reading speed: 65536 bytes/14 machine cycle (T)

2, Chinese Card memory capacity:

The 512K byte is used for the store various kinds of data form.

The 256K byte is used to store GB I and II Chinese character base and symbol.

The 256K byte is left for to expand and is used.

3, Chinese Card is 62 buses, is applicable to: various original-pack and compatible PC/XT machines, 0520 family machine; Various original-pack and compatible AT machines, 0530 family machine; 386 machines, 0540 family machine.

4, software can be finished demonstration, and prompting shows, functions such as making speech is printed in input, and making the speech capacity is 60K byte (as if about about 5000 of 4 words).
