Abstract

The invention discloses a method for judging and storing concatenation of Uyghur based on an embedded system; the method comprises the steps of: constituting character sets according to Uyghur head parts, Uyghur middle parts and Uyghur tail parts based on a Uyghur unicode extended code according to language characteristics of Uyghur, judging whether a word is connected with a front one, a back one or both front and back ones or is an independent word according to variations at the head part, middle part or tail part of the word, and deforming; by taking a standard 8*16 word stock as a criterion, taking out actually used Uyghur characters displayed in an intelligent terminal interface to generate a new simplified Uyghur literal pool. According to the method, the problem that at present Uyghur is low in inputting efficiency and storing speed and requires large storage space can be solved, and a spelling and storing method applicable to the characteristics of Uyghur is provided.

Description

The judgement of Uighur write the two or more syllables of a word together and storage means based on embedded system

Technical field

The present invention relates to Uighur areas of information technology, particularly the judgement of the Uighur write the two or more syllables of a word together based on embedded system and storage means.

Background technology

In recent years, along with the development of ethnic group's informationization and automatic field, smart machine in Xinjiang based on embedded system has also had application more widely in ethnic group, but the educational level between each department, various nationalities differs greatly, apply intelligent terminal to the user of ethnic group and brought certain difficulty.

Summary of the invention

The object of the present invention is to provide a kind of judgement of Uighur write the two or more syllables of a word together and storage means based on embedded system, can solve that current Uighur input efficiency is slow, memory rate is slow, the problems such as required storage space is large, and proposed according to the spelling and the storage means that are applicable to Uighur language feature.

The object of the present invention is achieved like this: a kind of judgement of Uighur write the two or more syllables of a word together and storage means based on embedded system, according to Uighur language feature, taking Uighur unicode extended code as basis, and according in Uighur prefix, word, suffix forms separately character set and it is at prefix, different with the position of suffix in word, judge whether to connect before word rear company, middle (connecting) or an independent word, be out of shape; Taking standard 8 × 16 character libraries as benchmark, take out the intelligent terminal interface display actual Uyghur Character of using, generated a new Uighur character library of simplifying.

Uighur transformation rule processing: Uyghur Character belongs to Arabic word series, arabian writing spreads very wide under Mohammedan impact.Farsi, the Wu Er kinds of words such as Kazak, kirgiz in the Xinjiang of literary composition and China adopts Arabic alphabet.The letter of Uighur does not have the differentiation of upper case and lower case, but has the difference of block letter and clerical type, and removes

beyond these five letters, other 27 letters can with alphabetical write the two or more syllables of a word together below, and different with the position of suffix in prefix, word because of it, font also changes to some extent.

The presentation direction of Uyghur Character is different with Chinese, it is that right-to-left is write sidewards, therefore, the books of Uighur and book are all right formats, in line feed, usually, need to judge whether be whole word, carry out the line feed of whole word, and word can not be splitted into two parts, the numeral of Uighur the inside still adopts display mode from left to right.According to point-score above, be divided into first, last, middle, alone, and judge whether to connect before word (above character set 1 in), rear company (character is in set 2 below), middle (, connect, before character in gathering 1, character is in set 2 below) or an independent word, be out of shape.According to above-mentioned analysis, provide the array of distortion: corresponding situation above respectively.For other, not in array, its distortion is identical with self.For example: program execution step of the present invention is as follows:

const WORD Arbic_Position[][4]= // first, last, middle, alone

{

{ 0xfe90, 0xfe91, 0xfe92, 0xfe8f}, // 0x628

{ 0xfe94, 0xfe93, 0xfe93, 0xfe93},

{ 0xfe96, 0xfe97, 0xfe98, 0xfe95}, // 0x62A

{ 0xfe9a, 0xfe9b, 0xfe9c, 0xfe99},

{ 0xfe9e, 0xfe9f, 0xfea0, 0xfe9d},

{ 0xfea2, 0xfea3, 0xfea4, 0xfea1},

{ 0xfea6, 0xfea7, 0xfea8, 0xfea5},

{ 0xfeaa, 0xfea9, 0xfeaa, 0xfea9},

……

}

Judge whether to connect above, adopt and judge that the decision method of the previous character of this character, method are, see that previous character is whether gathering in set1.If, there is connection above.Gather 1 as follows:

static U16 theSet1[23]={

0x62c， 0x62d， 0x62e， 0x647， 0x639， 0x63a， 0x641， 0x642，

0x62b， 0x635， 0x636， 0x637， 0x643， 0x645， 0x646， 0x62a，

0x644， 0x628， 0x64a， 0x633， 0x634， 0x638， 0x626};

Judge whether to connect below, adopt the decision method that judge a character after this character, method is, sees that a rear character is whether gathering in set2.If, there is connection below.Gather 2 as follows:

static U16 theSet2[35]={

0x62c， 0x62d， 0x62e， 0x647， 0x639， 0x63a， 0x641， 0x642，

0x62b， 0x635， 0x636， 0x637， 0x643， 0x645， 0x646， 0x62a，

0x644， 0x628， 0x64a， 0x633， 0x634， 0x638， 0x626，

0x627， 0x623， 0x625， 0x622， 0x62f， 0x630， 0x631， 0x632，

0x648， 0x624， 0x629， 0x649};

Hyphen is that character string is below 0x622,0x623 with 0x644 beginning, 0x625,0x627, and according to circumstances take off the character array 0 or 1 of face, if the previous character of 0x644 is the set 1 on set 1(is same) in the middle of, peek group 1, otherwise peek group 0.

Array is as follows: static U16 arabic_specs[] [2]=0xFEF5,0xFEF6},

{0xFEF7，0xFEF8}，

{0xFEF9，0xFEFA}，

{0xFEFB，0xFEFC}，

};

For example: 0x064A, 0x0644,0x0622

A character 0x0644 below of 0x064A, in set 2, show that according to coding rule 1 it is rear hyphen (last), therefore convert to: 0xFEF3. and 0x064A are in set 1, therefore substitute these two codings of 0x0644 0x0622 with 0xFEF6.

In order to save storage space, design a kind of character library extraction procedure, taking standard 8 × 16 character libraries as benchmark, take out the intelligent terminal interface display actual Uyghur Character of using, generated a new Uighur character library of simplifying.For example, show the Uighur of " voltage ", its corresponding extended code is " FE97; FEEE; FED9; FE91, FBE7, FEB4; FEE4; FEF0 ", and the character library generating according to Uyghur Character extended code is found out the dot matrix font that this word shows, wherein the computing formula of dot matrix font address is Uaddr=zkfile+uiger_length × 2+x × 16, wherein, zkfile is the first address of Uighur font file in storer, and uiger_length is the sum of Uyghur Character in character library, and X is its position in character library.The present invention can solve the problems such as current Uighur input efficiency is slow, memory rate is slow, and required storage space is large, and has proposed according to the spelling and the storage means that are applicable to Uighur language feature.
