Thiết kế trình biên dịch: Nguyên lý, Kỹ thuật và Công cụ

Course Objectives:

1. Introduce the major concepts of language translation and compiler design and impart the knowledge of practical skills necessary for constructing a compiler.

2. Topics include phases of compiler, parsing, syntax directed translation, type checking use of symbol tables, code optimization techniques, intermediate code generation, code generation and data flow analysis.

Course Outcomes:

1. Demonstrate the ability to design a compiler given a set of language features.

2. Demonstrate the the knowledge of patterns, tokens & regular expressions for lexical analysis.

3. Acquire skills in using lex tool & yacc tool for developing a scanner and parser.

4. Design and implement LL and LR parsers

5. Design algorithms to do code optimization in order to improve the performance of a program in terms of space and time complexity.

6. Design algorithms to generate machine code.
