Grammar said the machines; 2. LASTVT FIRSTVT sets and set computing; 3. Operator precedence relations of the matrix structure.

philips的lpc2131工程模块,需添加到ads1.2下的工程模块目录下,不知道有没有人需要-Philips lpc2131 the project modules, that should be added to the project ads1.2 module directory, we do not know whether any of them need

该项目的目的是设计和实施，为的沟通通过其JTAG接口和控制是通过设置断点和寄存器和存储器访问程序的执行能力ATmega644调试。-The purpose of this project was to design and implement a debugger for the ATmega644 that communicated through its JTAG interface and was capable of controlling program execution by setting breakpoints and accessing registers and memory

编译原理程序by me.- Translation principle procedure by me.

词法分析程序，是一个词法分析程序，可以分析单词，指出错误。-lexical analysis procedure is a lexical analysis procedures can be analyzed word that mistake.

这是一份实验报告，目的是掌握YACC的使用方法，了解YACC处理二义性的方法。 用YACC等工具生成如下文法表示的表达式对应的计算器 exp->exp + exp | exp - exp| exp * exp |exp / exp |exp ^ exp | - exp |(exp) |NUM 对于输入的表达式，能输出结果。比如: 3 +(4 *5)结果应为23 当出现错误时可以进行错误处理。 -This is a test report, the purpose is to master the use YACC to learn YACC handling of the ambiguity approach. Using tools such as YACC grammar that generates the following expression for the corresponding calculator exp-> exp+ exp | exp- exp | exp* exp | exp/exp | exp ^ exp |- exp | (exp) | NUM expression for the input type, can be output. For example: 3+ (4* 5) the result should be 23 when the error can be error-handling.

一个简单的解析器，可以对四则运算和if语句进行解析，利用简单扫描的方式词法解析，和压栈方式解释运算，可以帮助学习编译原理-a simple parser can be four operators and if statements for the analysis, simple scanning the lexical analysis, and interpretation Yazhan Operators can help compiler theory

本代码为根据老师的课程设计要求做的小编译器的词法分析部分和语法分析部分，附件中有老师的要求文档，还有语法分析时使用到的分析表-This code is based on the teacher" s curriculum design requirements to do a small part of the compiler" s lexical analysis and syntax analysis section, in the annex to the request of the teacher documents, as well as the use of grammatical analysis to the analysis table

max-log-map算法的C语言的实现，能计算出所需要的LLR，做出软判决和硬判决。-max-log-map algorithm for the realization of the C language, can be required to calculate LLR, make a hard decision and soft decision.
