Problems solved by technology

[0003] The basic set of 6763 Chinese characters is often used in embedded computer systems. When the Chinese character code represented by the 14-bit binary number of GB2312-1980 is used to exchange information containing Chinese characters in serial mode in the embedded computer system, the information exchange efficiency is low, and the information exchange longer time

Embodiment 1

[0033] The Chinese character "good", the 14-bit code found in Fig. 1-2 is 0x3A43, namely A=0x3A, B=0x43. Substitute into formulas 1 and 2 to get:

[0034] a=(0x3A-0x30)*4+|0x43 / 0x20|Take the quotient

[0035] = 0x2A,

[0036] b=0x43%0x20

[0037] = 0x03;

[0038] That is, the 13-digit code converted from "good" is 0x2A03. Check Figure 2-8 to know that the conversion is correct.

Embodiment 2

[0040] The Chinese character "齄", the 14-bit code found in Figure 1-15 is 0x777E, that is, A=0x77, B=0x7E. Substitute into formulas 1 and 2 to get:

[0041] a=0x77-0x40

[0042] = 0x37,

[0043] b=0x7E;

[0044] That is to say, the 13-digit code converted from "齄" is 0x377E. Check Figure 2-14 to know that the conversion is correct.

[0045] 2. The method of converting the 13-digit Chinese character code into the 14-digit Chinese character code of GB2312-1980

Embodiment 3

[0047] The Chinese character "good", in Figure 2-8, finds that the 13-bit code is 0x2A03, that is, a=0x2A, b=0x03. Substitute into formulas 3 and 4 to get:

[0048] A=0x30+|0x2A / 4|Take the quotient

[0049] = 0x3A,

[0050] B=0x03+(0x2A&3)*0x20

[0051] = 0x43;

[0052] That is, the 14-bit code converted from "good" is 0x3A43. Check Figure 1-2 to know that the conversion is correct.

Abstract

The invention is concerned with the 13 bits coding method of basic Chinese character that uses to exchange information, the characteristic is: uses the 13 bits binary system numeral to express the Chinese characters set for GB2312-1980 information exchanging, the set uses 14 bits binary system numeral to express the Chinese characters code. The advantages of the invention are: saves one bit binary system numeral bit, and the invention gives the simple arithmetic of the two codes. The invention can improve the information exchange efficiency and saves the information exchange time.

Description

technical field [0001] The invention relates to a 13-bit encoding method of basic set Chinese characters for information exchange, which is used in the technical field of information exchange in information technology, that is, communication, computer information exchange and processing, and belongs to the technical field of Chinese character encoding methods. Background technique [0002] GB2312-1980 "Basic Set of Coded Chinese Characters for Information Interchange" provides a coding method for the 6763 Chinese characters in the basic set. The Chinese character area shown in Figure 1 is given in "Table 1 Graphical Character Code Table" The code of these Chinese characters, its code is made up of first byte and second byte, uses 14 binary numbers. This Chinese character area starts from 0x3021, which is the Chinese character "ah" to 0x777E, which is the Chinese character "齄". 0x means that there are hexadecimal numbers after it, the first two digits are the first byte, and ...
