Laboratory Works:
The laboratory work includes Assembly language programming using 8085/8086/8088 trainer kit. The programming should include: Arithmetic operation, base conversion, conditional branching etc. The lab work list may include following concepts:
- Assembly language program using 8085 microprocessor kit.
- Use of all types of instructions and addressing modes.
- Arrays and the concept of Multiplications and Division operations on Microprocessor.
- Assembly language programming, using any types of Assembler, including the different functions of Int 10h, and 12h
