The report recorded a big operation principle compile process and different stages of the design, including lexical analysis, syntax analysis, semantic analysis and compilation of code generation in four stages, in grammatical analysis, I have used two types of syntax analysis, that is, a self- top-down method of syntax analysis- LL (1) analysis, and the other is bottom-up grammar analysis- SLR (1) analysis, so that it can be seen that the basic analysis of two different methods, such stage in the semantic analysis of these two methods to deal with sub-semantic actions, and to the preparation of a generative semantics movement, respectively.
