你可以任意输入合法文法，给定任意的句子，将会分析出这个句子是不是文法的的句子...

一般的FOrtran程序编译器只能检查一般的错误，而这个软件可以起到一般编译器不能起到的错误检查、程序优化作用。-Ftnchek (short for Fortran checker) is designed to detect certain errors in a Fortran program that a compiler usually does not. Ftnchek is not primarily intended to detect syntax errors. Its purpose is to assist the user in finding semantic errors. Semantic errors are legal in the Fortran language but are wasteful or may cause incorrect operation. For example, variables which are never used may indicate some omission in the program uninitialized variables contain garbage which may cause incorrect results to be calculated and variables which are not declared may not have the intended type. Ftnchek is written in C. To build ftnchek, you must have a C compiler for the machine on which you wish to build it. The URL for ftnchek s home page is http://www.dsm.fordham.edu/~ftnchek. Source code, binary executables for some platforms, and other information are available there.

语义分析的功能： 第一，审查每个语法结构的静态语义，即验证语法结构合法的程序是否真正有意义。有时把这个工作称为静态语义分析或静态审查。第二，如果静态语义正确，语义处理则要执行真正的翻译，即，或者将源程序翻译成程序的一种中间表示形式（中间代码），或者将源程序翻译成目标代码。 有报告-Semantic analysis of the functions: First, review each of the grammatical structure of the static semantics, that is, the grammatical structure to verify whether the procedures legally meaningful. Sometimes this is called static or static semantic analysis review. Secondly, if the correct static semantics, semantic processing should be the implementation of a genuine translation, that is, or will be translated into procedures source an intermediate representation (intermediate code), or source code translated into object code. There are reports

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

中山大学编译原理课程的一个实验，根据OPP(算符优先)做的一个表达式计算器。 内有实验的设计文档。 实验要求支持sin,cos,max,min,power,mod,boolean,?:,等运算。 这个代码可以为学习编译原理的同学参考。-Principles of Sun Yat-sen University to compile an experimental course, according to OPP (operator priority) to do an expression calculator. There are experimental design documents. Experimental requirements to support the sin, cos, max, min, power, mod, boolean,?:, Such as computing. This code can be compiled for study and reference principles classmates.
