Study Notes
Assembly Language Overview
- Assembly language simplifies machine level language by using mnemonic symbols instead of binary codes.
- Mnemonics resemble English words, making instructions more understandable (e.g., ADD, SUB, COMP, MOV).
- Example of an assembly instruction: A add B = C, illustrating how operations are represented in a readable format.
Translation Requirement
- Assembly language programs require translation into machine language for execution by the hardware.
- This translation is achieved using assemblers, which convert mnemonics to corresponding machine code.
Compiler Overview
- A compiler translates high-level programming code into machine language.
- The original code written in a high-level language is referred to as the source program.
- The converted code in machine language is called the object program.
Error Detection and Handling
- Compilers perform comprehensive error checking throughout the source code.
- All detected errors are listed for the programmer to address before execution.
- Only if the program is free of errors will the compiler proceed to translate it into machine code.
Execution of Programs
- Once successfully compiled, the executable machine code can run independently of the source program.
- This separation allows for more efficient execution and debugging processes.
