Compiler Design is the structure and set of principles that guide the translation, analysis, and optimization process of a compiler. A Compiler is computer software that transforms program source code that is written in a high-level language into low-level machine code. It essentially translates the code written in one programming language to another language without changing the logic of the code. The Compiler also makes the code output efficient and optimized for execution time and memory space. The compiling process has basic translation mechanisms and error detection, it can’t compile code if there is an error. The compiler process runs through syntax, lexical, and semantic analysis in the front end and generates optimized code in the back end. This course plan has been designed keeping all kinds of learners in mind. The detailed course is specially planned for all the colleges and university students, also the required numerical problems from various PYQs pertaining to respective topics are to be included to provide clearer insight to any of the exam aspirants. The list of topics to be covered in order of top to bottom is as follows: 1. Introduction a. Symbol table b. Lexical analyzer 2. Syntax Analyzer a. Ambiguous & Unambiguous Grammar b. Left recursive & Right recursive Grammar c. Non-deterministic & Deterministic Grammar 3. Parsers-Top down a. Recursive Descent Parsers b. LL(1) Parsers 4. Parsers-Bottom up a. Operator Presence Parser b. LR Parsers 5. SDTS: Syntax-Directed Translation Scheme a. Top-down & Bottom-up Parsing b. Syntax Trees c. S-Attributed & L-Attributed SDTs 6. Intermediate Code Generation a. Three Address Codes 7. Runtime Environment & Code optimization a. Loop optimizations https://www.nesoacademy.org/cs/12-compiler-design
