unix v6 的c compiler 很老了 ，但很有研究价值

编译原理课程设计，词法分析，语法分析，语义分析等。-compiler theory curriculum design, lexical analysis, grammar analysis, semantic analysis.

语法分析器 完成从c/c++向C++转变-parser from complete c/c to C change

多功能运算器- Multi-purpose logic unit

编译原理词法分析器,生成二元式的代码！适合于大学计算机科学与技术实验设计。-compiler

#include "define.h" #include #include #include #include FILE *fp /*////////////////////////////////////////////////////////////////////////////// This is a pretreatment. /////////////////////////////////////////////////////////////////////////////*/ void readIntoBuffer(char buffer[256]) { char ch1 char temp int i for(i=0 i

状态转换矩阵 用来判断运算符的正确性- The phase transition matrix uses for to judge the operator the accuracy

上个用VHDL语言写的音乐程序,希望对大家能够有帮助-In the use of VHDL language music program, and they hope to have everyone be able to help

一个用LISP语言编写的语法分析器。使用Bottom-up Chart Parsing算法，程序非常的简单高效，只有二百多行。另外可以自己定义文法和字典。 源代码公开，主要供对语法分析算法和LISP编程感兴趣的人学习使用，也可以使用在自然语言处理的各种实际研究当中。-A language with LISP parser. The use of Bottom-up Chart Parsing algorithm, the procedure very simple and efficient, and only more than 200 lines. In addition to its own grammar and dictionary definition. Open source code, mainly for syntax analysis of the LISP programming algorithms and people interested in learning to use, you can also use natural language processing in a variety of actual studies.

按递归下降方式设计其编译程序，生成PL/0栈式指令代码，然后解释执行。用(a=1)+2*(b=3+4*5)/2+2*a*b-(a=a+5)/ (c=2) 测试-dropped by recursive approach to design their own compiler, generating PL/0 Stack-code instructions, and then the interpretation and implementation. Using (a = 1) 2* (b = 3 4* 5)/2* a* b- (a = 5 a)/(c = 2) Testing

实现词法分析,用VB写的对结果进行分类显示-achieve lexical analysis using VB wrote to the classification results show
