编译原理实验中的工具FLEX,可以再windows或者DOS下使用

CRC码的几种编码程序，但缺少一种VHDL的，还望大家补充下联系我。-thanks

可以求你需要的汇率转换- May you need in order to the exchange rate transforms

目的：通过编写简单的YACC程序熟悉YACC词法分析工具的基本用法，及词法分析器的设计思路。编写包括赋值语句、if语句以及含有加合乘运算的表达式等语法结构的pascal子集语言的语法分析器。 功能：程序由两个模块LEX和YACC构成，YACC使用LEX分析后的正规单词输出流-Objective : to prepare a simple procedure with YACC YACC lexical analysis of the basic tools to use, and the lexical analyzer designs. Preparation including assignment if statements containing Addition and multiplication of expressions such as grammatical structure of the pascal subset of the language syntax analyzer. Function : procedures by the two modules constitute LEX and YACC, YACC LEX analysis using the formal word output streams

一个语法分析，能实现SLR语法分析，是一个好的语法分析器-A parsing,which can realize SLR parsing,is a good parsing analyzer.

avr 程序开发中可以用到BOOTLOADER程序、ISP汇编程序ISP C程序-avr program development process can be used BootLoader, ISP assembler procedures ISP C

编译原理词法分析，将源文件分类存入文件，供语法分析使用-Compiler Construction Principles lexical analysis, classification of documents into the source document for the use of grammatical analysis

实现NFA确定化子集算法程序。DFA是NFA的特例。对每个NFA 　N一定存在一个DFA　Ｍ ，使得 L(M)=L(N)。对每个NFA N存在着与之等价的DFA M。从NFA的矩阵表示中可以看出，表项通常是一状态的集合，而在DFA的矩阵表示中，表项是一个状态，NFA到相应的DFA的构造的基本思路是：1.DFA的每一个状态对应NFA的一组状态. 2. DFA使用它的状态去记录在NFA读入一个输入符号后可能达到的所有状态.。-achieve NFA Number algorithm to determine procedures. DFA NFA is a special case. NFA N for each must exist a DFA M, makes L (M) = L (N). N for each NFA exist with the DFA M equivalent. NFA from the matrix can be seen, tables are usually set of a state, and in the matrix DFA said, Form is a state of the corresponding NFA DFA basic structure of ideas : 1.DFA each one corresponds to a group of NFA state. 2. DFA use it to the state records in NFA Reading input into a symbol after all reach the state. .

Fenris是一个检测并把高层次的语言结构做成文档的多功能故障检测器、调试器、代码分析工具。它能回复符号，把程序执行流绘成图，检查内部运行情况，恢复符号表，并处理反调试保护。它有一个命令行接口和一个类似SoftICE的GUI与Web前端-Fenris is a detection and high-level language structure made of multifunctional document fault detection, debugging, code analysis tools. It can restore symbols, compose program execution flow map, check their internal operations, restoration of the symbol table, and to deal with anti-debugging protection. It is a command line interface and a similar SoftICE with the GUI front-end Web

一个程序，用于判定给定的文法是否为LL（1）文法。 实现了：1．文法的机内表示；2. FIRST集和FOLLOW集的计算； 3. LL（1）预测分析表的构造。-a procedure for the determination of grammar to whether LL (1) grammar. Realized : 1. Grammar said the machines; 2. FIRST FOLLOW sets and set computing; 3. LL (1) Forecast and Analysis table structure.
