1.1 引言 1.1.1 设计目的 本次课程设计是在完成一个学期的编译原理课程之后，为了进一步加深对编译原理相关知识的理解，培养实际解决问题的能力而进行的。结合本学期所开设的软件工程课程，本次课程设计实验过程要求按照软件工程的思想来组织开发过程，按照软件生命周期的阶段划分来进行。由于课程设计规模较小，所以对软件生命周期进行适当的合并，简化为五个阶段，即需求分析、总体设计、详细设计、编码实现和测试。 1.1.2 设计任务 针对本次课程设计我们设计了一个简化的pascal语言，称为mini-pascal。设计的任务就是开发出针对mini-pascal语言的编译程序。标准的编译程序结构分为五部分，分别是词法分析、语法分析、语义分析和中间代码生成、优化和目标代码生成。由于时间和能力所限，我们的编译程序只包括前三个部分，最后生成四元式形式的中间代码。 -1.1 Introduction 1.1.1 design purpose of this course is designed to complete a semester of compiler theory courses , in order to further deepen the knowledge of compiler theory understanding, develop practical problem-solving skills into practice.
