8086 Microprocessor Architecture: Assembly Language, Memory Interfacing, and I/O

8086 Microprocessor Architecture

Assembly Language Programming

Assembly language uses mnemonics to represent low-level instructions understood by the microprocessor. The assembler converts these instructions into binary code (0s and 1s) for execution. Here are some key rules for 8086 assembly language programming:

  • Code must be written in uppercase letters.
  • Labels must be followed by a colon (e.g., label:).
  • Labels and symbols must begin with a letter.
