5509开发板测试程序,通过观测XF引脚是否有方波来初步估计试验板硬件是否有问题...

叟皆了51的汇编代码，希望读大家有所帮助-Minds are 51 assembly code, I hope everyone reading help

构造实验一所给文法（应考虑改造）的FIRST集合和FOLLOW集合；构造LL(1)分析表；构造预测分析的总控程序；利用分析表、分析栈和总控程序对源程序进行自上而下的语法分输出整个语法分析过程中栈的变化过程及分析结果，如符合语法规则输出“正确”，否则输出“错误”。 -Experiment to construct a grammar (should consider the transformation) of FIRST and FOLLOW set of the collection construct LL (1) analysis table structural prediction analysis of the master control procedures the use of analytical tables, analyze the stack and the total source code control procedures carried out since the last sub output down syntax parsing process of the whole stack and analysis of the results of the change process, such as the grammatical rules out the " right" , otherwise output " error."

编译原理实践教程PL0语言编译程序源代码。参考书：清华大学出版社的《编译原理》作者吕映芝、张素琴等。 实现主要功能有：对使用PL0语言编写的程序进行词法分析，查看词法分析的结果，语法分析， 生成中间代码并可供查看，以及解释执行。 压缩包中含有实验报告文本，其中有程序中各功能模块及主要功能的详细说明。-Compilation Principle Practice Guide PL0 source language compiler. Reference: Tsinghua University Press, Compiler Construction Principles author Lu Ying-chi, such as Su-Qin Zhang. The realization of the main functions are: the use of language PL0 lexical analysis procedure to see the results of lexical analysis, syntax analysis, intermediate code generation and will also be available to view and explain the implementation. Experimental package contains the text of the report, including detailed description of every functional process modules and main functions.
