Unit 2.5 - Translators & Facilities

1. Key Words

   • Compiler
   • Interpreter
   • Assembler
   • Source Code
   • Object Code
   • Excecuteable Code
   • Debug
   • Translator
   • IDE (Integrated Development Environment

2. Assemblers

   • Translate Assembly Code into Machine Code
   • Used for device drivers
   • Used when fast execution is required or limited memory/file size
   • Difficult to write in
   • An assembler's purpose is to turn a second gen assembly code into machine code

3. Compilers

   • Translate entire source code all in one go into machine code
   • Optimise code
   • Used at he end of development
   • Error reports created along with object code

4. Interpreters

   • Translate & Execute source code
   • Line by line
   • Source Code is checked for syntax - if correct, code is executed. If incorrect, interpreting is stopped
   • Used for developing (aid debugging)

5. IDE (Integrated Development Environment)

   • Editor (for writing the code)
   • Error diagnostics
   • Runtime environment
   • Translators
