Study Notes

Computer System Components

A computer system consists of hardware and software components.

Compilation Process

Lexical analysis is the first phase of compilation, which breaks the source code into a series of tokens.
The purpose of lexical analysis is to identify the keywords, identifiers, and symbols in the source code.

Compiler Role

A compiler translates source code into machine code, allowing the computer to execute the program.
The main function of a software compiler is to translate high-level language code into low-level machine code.

Binary Code

Binary codes are difficult to work with because they are represented as a series of 0s and 1s, making them hard to read and understand.

Hardware Component Role

The hardware component of a computer system executes the machine code generated by the compiler.

Syntax Analysis Phase

The purpose of the Syntax Analysis phase is to check if the tokens produced by the lexical analyzer follow the rules of the language.

Semantic Analyzer Phase

The Semantic Analyzer phase checks the meaning of the source code, ensuring that it is semantically correct.

Intermediate Code Generator Phase

The Intermediate Code Generator phase produces an intermediate code, which is independent of the target machine.

Cross Compiler

The primary function of a cross compiler is to compile code for a different platform or architecture.
Retargeting in the context of cross compilers refers to the process of generating code for a different target machine.

Code Generation Phase

The Code Generation phase produces the final machine language code.

Synthesis Phase

The Code Generation phase bridges the analysis and synthesis phase of translation.

Code Optimizer Phase

The primary function of the Code Optimizer phase is to improve the efficiency and performance of the generated code.

Parse Tree Construction

The Syntax Analysis phase takes tokens produced by the lexical analyzer as input and constructs a parse tree.
The Syntax Analysis phase checks whether the parse tree constructed follows the rules of the language.
