Introduction of Complier Design:- Unit :- 1
Compiler design is a branch of computer science and engineering focused on creating compilers, which are programs that translate high-level source code written by programmers into low-level machine code understood by computers. It involves lexical analysis, syntax analysis, semantic analysis, optimization, and code generation to ensure efficient and correct code execution.

Lexical Analysis (scanner): Unit:- 1
Lexical Analysis, or scanning, in compiler design, is the process of converting a sequence of characters from source code into a sequence of tokens. These tokens represent meaningful symbols, keywords, identifiers, and operators, which are used by the parser in the next phase of compilation. The lexical analyzer removes whitespace and comments, simplifying the syntactic analysis.

Syntax Analysis (Parser):- Unit :- 2
Syntax Analysis, or parsing, in compiler design is the process of analyzing a sequence of tokens to ensure they follow the grammatical structure of a programming language. It constructs a parse tree or syntax tree, representing the hierarchical structure of the source code according to the language's rules. This phase detects and reports syntax errors, facilitating correct code generation in subsequent stages.

Semantic Analysis:- Unit 2
Semantic analysis in compiler design is the phase where the compiler adds semantic meaning to the parsed syntax tree, ensuring the program adheres to language rules. It involves checking for type errors, variable declarations, and function calls, ensuring logical correctness beyond syntactic structure.

Intermediate Code Generation:- Unit 3
Intermediate Code Generation in compiler design involves translating high-level source code into an intermediate representation (IR). This IR acts as a bridge between the source code and machine code, optimizing the program and making it easier to translate into different target languages or architectures.

Code Improvement (optimization):- Unit :- 3
Code improvement (optimization) in compiler design refers to the process of enhancing the performance and efficiency of the generated code by making it run faster, use fewer resources, or consume less power without altering its output or functionality. This involves techniques like loop optimization, dead code elimination, and instruction scheduling to achieve a more efficient executable program.

Target code generation:- Unit:- 4
Target code generation in compiler design is the phase where the intermediate representation of a source program is translated into the target language, typically machine code. This step involves mapping high-level constructs to low-level instructions, ensuring optimization for performance and resource utilization, and generating executable code for the target hardware.
